Types of material handling equipment’s










elevator

- Bucket elevator (or elevating conveyors)

are used for transporting dry granular materials in the vertical direction with help of buckets and trays.

- There also known as bucket elevating conveyors and carry the material in bucket to vertical or near vertical positions.

- There are (i) either chain bucket elevator in which buckets are attached to one or two chains which move one two end wheels or (ii) belt bucket elevators in which buckets are attached to the belt moving on pulleys provided at two ends. 






- Bucket elevator are operated between head and foot terminal machinery in a supporting frame. The bucket are loaded by scope action at foot end or by a chute above.

- Belt type have higher speed and capacity smoother and quieter which chain types are heavier duty and suitable for abrasive material bucket elevators are sometime used as portable elevators which are known as stackers consists of a base on wheels a vertical frame a lifting or lowering mechanism and a load carrying platform.

- Lifting of such elevators is accomplished by hydraulic or mechanical action.

- Bucket elevator are consists of an endless chain of buckets which bucket elevators the material. Theel evator is usually enclosed in a sheet of metal casing with necessary inlet and out let openings and chutes. They are widely used in handling cools chemicals cement etc.

- Bucket elevators consist of a line of pivoted buckets end mounted between two strands of rivet less chains so that the center of gravity is below the pivot in every bucket.

- As a results buckets travel in stable equilibrium and automatically drop back into the horizontal position after being discharge by tilling.

- Normal operating speeds of those conveyors is between 0.15 and 0. 40 m/sec. these conveyors are available up to 400 tons/ltr.

- Normal lifts of those range up to 30 meters but in special cases may range up to 100 meters.

- For unloading tripping arrangement are used in the form of fixed or moveable devices. On being overturned as the point of discharge buckets become back into the original position.

- In a bucket conveyors freely swinging (pivoted) buckets are carried between a parallel endless chains which follow any path vertical horizontal or inclined.

- The bucket are loaded by a specially designed feeder and are unloaded when they are tripped or inverted at set point these are rugged slow running and capable of providing trouble free service. 




- Screw conveyors also known as spiral conveyors consist of a screw rotating in a stationary through or tube. As the shaft on which screw type spiral blade causes the material to be pushed forward along the through.

- Screw conveyors can be operated in a horizontal inclined or even vertical upward direction while the materials are being moved the screw conveyors can also be used to perform the process of blinding and mining of materials.

- These are used to move materials over a through by rotating screw. This is formed by a helical blade attached to a drive shaft which is coupled to a drive and supported by end bearings and by inner bearings.

- The through of the round bottom shape is topped by a cover plate with an opening for loading the conveyor.

- A similar unloading opening is provided in the bottom of the through. The helical blade forcing the load along the through when the shaft is set rotating is made of 4- 8 mm steel plate and attached to the shaft by welding.

- Helical spiral blade are used for dry materials ranging in size from powder to lumps ribbon spiral blades are used to handle coarsely broken and sticky loads. Paddle spiral and cut flights are adopted to convey flow resistant solids tending to cake.

- Screw conveyors are widely used to handle dusty or hot loads liberating harmful gases these are also used for handling powders foods products pulverized coal (for feeding into the furnace) or other granular materials.

- Screw conveyors can also operate vertically lifting material up to 150 m. screw feeder or a horizontal screw conveyors which serve to create a thrust at the food of the lifting 




Vibratory conveyors

- In vibrating conveyor vibrations are created at high frequency and small amplitude. The vibration are induced electrically or mechanically.

- These conveyors are rugged require low maintenance.

- These conveyors are generally used as a feeder and for screening blending or separating.

- These conveyors are fitted with metal or plastic through over which materials consisting of fragments of varying size are kept which while moving are separated at a high speed.

- For designing a vibratory conveyor it is essential to specially nature of material to be handled indicating density grain size and other characteristics. 

Feeders and screw

- During processing in any industry it is essential for effective and efficient performance to have uniformly controlled feed.

- Uniform feeding operation and its control is obtained either by mechanical or electrical means.

Mechanical feeders are generally of 3 types:-

1. Adjustable feed opening.

2. Adjustable speed

3. Vibratory.

- In order to control the feeding rate or to achieve the varying feeding requirements mechanical feeders ( generally hoppers) are equipped with provision of adjusting the gates at feed opening or variable speeds drives.

- Selection of the type and size of the feeder depends upon capacity requirement material characteristics and size flow ability moisture contents etc. commonly used feeding

 arrangements are:-

1. Belt feeders

These are the short belts and feeds the material

at a uniform rates. These are provided at the

 bottom of the hopper and extracts the material

from it. For varying the rate of discharge the

 speed of feed belt is varied as per requirement.




2. Hoppers with adjustable gates and

chutes

- These are used for feeding the material to the belt conveyors. These are used for uniform loading the running belt through a chute and the rate of material flow is controlled through the gates at the month of the chutes.

- These gates can be controlled either manually or hydraulically or electrically or by means of compressed air chute is used to discharge the material on the conveyor belt in its direction of movement so as to reduce the impact of material on belt.

- The size of the chute opening should be designed in such a way so as to avoid blockage of opening by lumpy materials if any. The inner walls of the chute should be lined with the anti-a brasive material.

- To avoid the spillage of material and guide. The material or belt two rubber pads are also provided on the sides at the loading point.



3. Vibrating feeders

- When loading non free flow material vibrating feeder are used. Vibrations are produced by electromagnet means are mechanical means. This feeding system is most suitable for all types of bulk materials may it be dry or damp hot or cold fume or coarse size grains.

- The vibrating mechanism is fitted either on wall of the hopper above the chute or in case of rectangular container the device is fitted at the bottom plate to produce vibrations. 

Drag chains & cable  ways 
Drag chains 
- These are  used by chains or cables in horizontal  direction and  installed flush with  floor or a little above it. 
- This is used for  moving barrels and heavy boxes. This  is also used for  moving grates of big boilers and  serve as a  continuous  moving table. Chain conveyors  employ  continuous 
chains wrapped  around head and tail  end sprockets.
- The conveyors  units are  generally operated  by motor drives  attached to  the head  drive 
shaft. Material  can be carried  directly on a  prone or  pushed in a trough  by flights  attached to the chain.
- The chain conveyors  may be apron flight bucket  car conveyors  depending upon the  type of attachment uses. The  units can  arranged for operation horizontally  inclined or in combination  these  can be designed to  operate  up to 45⁰ inclination.
- Capacity of  a chain conveyor is  equal to. Available  cross sectional  area แตก chain speed. 
Speed of the chain  depend upon the  type of  material and varies from 3-6 m/min for 
abrasive  material to  about 30 m/min or  more for  mild abrasive  material. 
- Chain conveyors  can be used at  elevated temps can  handle coarse  broken  material un-
 suitable for belt temps. Chain  positively transmit the  drive imported to it  by the sprocket and displays low stretch  ability nuclear a low. 
Cable  ways 
- Cable  way is a  single span overhead conveying system. In cable  way  while traversing load can be raised or  lowered at any point. This  is very  useful in excavation work in dams  work pits quarries etc.  where load are hoisted and moved horizontally. 
- These  are also used for transporting  and then  placing the concrete in concrete structure. A cable  ways is supported on  live  end  supports and  consists of the  track cable the carriage the traction rope and the heist rope as  shown in fig. 
- One  support heaving and  operating  gear is  known as head tower  while  the other is known as tail time. 
- A  track cable ( strong  steel cable) is stretched over  these  two and towers. The carriage is 
 attached to an  endless traction drown  under  the head tower. 
- The hoist rope is supported  between carriage and  the head tower  on the  carries hanging 
from the traction rope. The cable  ways are  generally operated at speeds  between 150-400 
m/min  during  level and  between 30- 100 m/min  during lifting and lowering. It  usually  carry a carriage load  between 3-10 tons. 

Bulk Bins hoppers Big Bags 
And utilized bulk operations A system of vertical and horizontal pipe having intake hoppers receiver filters dust filters bulk bins
with blowers and motors which carry particle of solid material by means of air pressure in the material handling system is called pneumatic conveyors. 
These are classified as:- 
1. positive pressure 
system In this system a blow creates the positive air flow in the pipe line and materials are injected into the air stream and below via the pre-set conveying path. 



2. Negative pressure (vacuum) system 
In this system vacuum is created in the pipe line. A suitable intake mechanism with a hopper and a receiving station is provided where material particles are separated from the moving air stream by tangential or cyclonic action and discharged to storage or process bins. 


3. Combination system 
- This employ both the positive and negative systems. In this systems vacuum is used for unloading of material from storage there after 
positive pressure is used for distributing into single or multiple storage bin. 
- Pneumatic conveyor are used for transporting dry granular material chemical ponder sand and cement etc. this system is cleaner dust free easy to install requires lesser staff to handle or operate and minimum interruption.


- Maintenance is also less since moving part are not involved. This system is popular for
handling cement on large scale construction work. The initial cost of this system is related
high and the use is limited to selected mate





- This type of conveyor system is economical because of the
i. Saving in the cost of bags & other packages.
ii. (Lass expenses on bulk handling)
iii. Less labor costs
iv. No chances of damages spillage or residual materials in the discarded bags.
- This factors determining the power requirements and the size of the equipment’s
are:-
i. The vertical lift.
ii. Horizontal pipe length.
iii. Size of material to be transported.
iv. Through put required.
A pneumatic conveying system consists of:-
1. Air supply unit
It is generally consist of blower gear box and a motor.
2. Feeder unit
It is used to transfer the material into pipeline. These should be able to with stand the abrasion
of the material to be transported.
3. Pipe lines
It should be storage enough to suit the properties of the conveyed material and the pressure of system.
4. Separation unit
It is usually employed for reporting the material at destination. These are high efficiency cyclone separators. 
Vehicle bulk handling system
Marine bulk material handling
- Cranes have wide application in bulk material handling system such as vehicles. Marine
construction projects industries and shipping etc.
- These are also used for lifting the load (may be construction materials, loose material
packages, Finished & semi-finished products in industries, containers etc.) and placing
them at desired place.
- For this purpose cranes have three motion in general namely: hoisting, derricking and
slewing these cranes are generally electrically operated. Diesel operated or may have diesel electric drive.




The cranes can be classified in following classes:-
1. Derrick cranes
- It consist of a mast, a boom, a bull wheel on
which it rotates about a vertical axis and
supporting members (known as gays).
- These cranes are very widely used in construction projects loading and unloading
cargo at ports, ship building, marine handling and vehicle handling plant erecting etc.
- These cranes can be used as tower cranes for the purpose of erecting of high industrial and
residential of height 100 m or above.
- The derrick cranes can also be designed to work as port lower cranes for containers heavy
vehicles, marines and general cargo handling. These are also be used as shipyard cranes
for ship building and ship repairing work with higher capacities and longer working radii.
- The derrick cranes are sometime mounted on rail wagons for quick transportation and for
working near rail lines. These cranes are available up to 40 tons with 25 m boom length and 15 ton on work radii .


 2 Mobile cranes
- Mobile cranes are either
• Crawler mounted
• Wheel mounted
- Crawlers mounted cranes are highly
maneuverable and have the ability to operate
on unmade ground of poor condition
- These move slowly and operate in a limited
area.
- Wheel mounted mobile cranes are generally truck mounted, have mobility, can travel up to
70-75 km/hr. good roods.
- These are designed for long distance travel with high rood speeds.
- The number of axles and drives depends upon load lifting capacity and the length of the
boom. These cranes can operate on firm ground. For increasing base width and to improve
stability during operation outriggers are used.


The mobile cranes have four motions:- 
i. Hoisting 
ii. Derricking 
iii. Slewing 
iv. Traveling 
- Rail mounted cranes are also manufactured to move on rail tracks. Such cranes are used in 
steel industry dockyard, railways. These cranes can be driven by diesel engines are by electricity. These are design suit the railway gauge clearance available to lift high loads such as required for salvage operation after accident etc.





. Hydraulic Cranes 
- Hydraulic cranes are usually truck mounted crane all operations of these cranes are 
hydraulically power including extension and reduction of outriggers extension and 
shortening of boom. 
- The hydraulic power is supplied through oil pressure generators by rotary oil pumps. 
Because of simplicity quick chain of boom length, easy and quick change of angle mobility 
and manor operability of the telescopic boom no requirement of a separate crew for 
extending are shorting of the boom. 
- The cranes have attained the wide popularity over conventional cable operator latticed 
boom. 
- Besides the operation of hoisting, slewing and derricking can be performed simultaneously 
and without any jerks which are unavoidable in conventional cranes. 
- These cranes mostly used in dockyards ware house sliding etc. for lifting and lowering 
heavy loads up to 250 tons. 
- Its main advantages over electric cranes is that these can be adopted to suit varying conditions. 
- Hydraulic cranes consists of two main parts 
1. Jigger 
2. Craning arrangement 
1. Hydraulic jigger 
- It is an arrangement of pulleys for increase the velocity ratio. It consists of a fixed cylinder in 
which a ram moves. A number of pulleys (2 to 6 fitted by sides by side) are fixed on the top 
of a ram and similar numbers is fixed at the end of the cylinder.
- A wire rope with one ends fixed at point on the cylinder is taken round all the pulleys on ram and cylinder alternately and finally to the other end is taken round a pulley fixed at the top of the mast (hollow vertical post) of the craning arrangement.

- It is then taken down after passing through a pulley fixed at the junction of jib and tie rods. 
At the free end a hook is provided for hang load. Jigger may be kept either horizontally or 
vertically.
2. Craning arrangement 
- The crane consist of a hollow vertical mast to which job and a tie rod is attached as 
showing in fig. 
- The mast is supported on bearing and can be revolved with its vertical axis so that load 
from a direction can be handled. The jib can be raised or lowered together with the load.
Overhead and Gantry Cranes 
- There are used for handling load over a long rectangular area in factories power station in 
shipyards and in workshops. 
- The simplest from manually consists of:- 
i) Structural bridged support of elevated tracks. 
ii) Supporting a lifting block or hoist trolley. 
- Control is made from a cabin on the bridged or from flow level. Due to freedom from flow 
abstractions these are widely used in erection foundries, steel plant, power houses and 
shipyard etc. 
- The bridged consist of two main girders which are fixed at the end and supported on train 
wheels and can move on gantry rails the hoist trolley (crab) is supported on these girders. 
- Thus load hook has three motions:- 
a) Hoisting lifting and lowering. 
b) Cross travelling with trolley in both directions. 
c) Longitudinal traversing with bridge in both directions. 






Traveler cranes 
- These cranes have their crabs (hoisting 
trolley) moving on girders which are 
supported on legs instead of overhead 
/gentry cranes. 
- The legs moves on tracks laid on the flow. 
Since these do not need overhead gantries hence are very useful as dock site cranes for 
lifting cargoes in shipyards and in docks etc.







Tower cranes
- Tower cranes are used in various construction projects of high buildings bridges, cooling towers, television towers, power plants and shipyards building etc.
- It can work and then dismantled as required
the lower has a truss structure welded from
angle bars and channels.
- Tower extension pieces are available to
increase the height as per requirements.
Ladders are provided inside the whole heights of the tower. An operation cabin is provided
and as to enable full view.
- Jib is attached to the last highest section of the lower. Two section of the jib opposite to one
another are provided one is saddle jib and another is counter weigh jib.
- A saddle move horizontally on rails provided on the saddle jib and is controlled from the
hook block. The upper portion of the tower is fixed in the slewing head.
Derrick:-
 A simple loading cranes that is typically used from moving cargo into or from ship.
Slew:-
A wet place to turn, swing, twist.
Crew:-
A group of people who work together on a project or task.
A crowd or gang:-
On board staff the people who work on a ship, air craft or space craft.
Riggers:-
To extend part of boat a beam or frame work sticking out from the side of a boat.
Jiggers:-
A device such a drill that operates with a jerking or jolting motion.
Jib:-
To shift from one side to other.






Material Handling

             



Material handling

- The materials handling is the movement of materials the movement of materials from one place to another is found within every organization and its study in materials handling is sometimes considered to be a separate discipline.

- It is in fact one aspect of work study and any materials handling problem must be solved by normal work study techniques. The purpose of the topic is to introduce some of the specialist equipment available for materials handling.

- The industries supermarkets offices construction project and the banks all are engaged in moving things/ materials. Materials handling generally costs between 20-30% of the cost of the product not only costs majority of production time is also consumed in handling the materials before during and after the manufacture.

- The materials handling time and cost can be reduced by proper selection operation maintenance and layout of these handling devices. In view of the fact it is the suggested that every manager should cause an investigation to be carried out on the materials handling costs within organize.

- Ignorance of the impact of the costs of the materials handling is required to pay full attention on this every important matter associated with the final cost of the product. It is frequently found that improvements in material handling provide the quickest and cheapest ways of improving profitability of the organization.Objective of materials handling

- Material handling is an art and science involving of the movement packaging and storing of products in any shape and from. Material handling is concerned with the following.


    

1. Movement

Materials handling involves movement of materials mechanically/manually in batches or one by one within the plant. It may be horizontal vertical or combination of two. It is concerned with movement of parts material and finished products from location to location.

2. Time

 Materials must arrive at its place at right time. It is to be ensured that no production process is distributed due to late arrival of materials.

3. Quantity

Material handling must ensure that each location continually receives the right quantity of materials ( parts raw materials semi- finished/ process items).

4. Space 

Space requirement are influenced by the materials handling flow pattern proper space is required for storage of raw materials, parts, semi- finished/ finished parts. 

5. Quality 

Quality  material be arrived at  right location. 



Material  handling  cost 

Material  handling  cost is  concerned of 

i. Cost of  handling. 

ii. Cost of transportation. 

iii. Cost of packaging. 

iv. Cost of space. 

v. Cost of  handling equipment ( including operation maintenance &depreciation etc) 

 In any  industry  materials  handling is of  three types 

a. Handling of  individual  part or unit. 

b. Handling in room  department or plant. 

c. Handling of  materials  during the  entire  process of  production and distribution  starting from  raw  material  source to disposal. 

This  can be  shown as below:- 

Raw  material → supplier → transportation → receiving → inspection → storing → issuance 

→ manufacturing/fabrication → packaging →shipping → dealer/distributor → retailers →

customer → disposal → re-cycling. 

Sine  materials  handling is  concerned with the  movement of the  materials  every  moment has. 

i. Picking up  the load. 

ii. Transporting  the load. 

iii. Setting  the load down. 



Causes of  high  material  handling costs.

 There are  some  cause of  high  materials  handling costs:- 

1. Ignorance of costs. 

2. Poor plant  layout. 

3. Poor  store  layout. 

4. Excessive  manual efforts. 

5. In-adequate/in- appropriate equipment. 

- It is to be  noted that  movement of  material  adds to the  cost of the product. 

- It is  therefore  important first to  reduce the  need for the  handling of  materials and  second to  reduce the  cost for that  handling  which is inevitable. 

- Any  material  handling  problem  must  start with the  layout of the  factory or  department  minimum distance i.e. all  movements be  both  (necessary and direct). 

-The second is concerned with the design of product which should be such during the various stages of manufacture, no un- necessary that the most economical design is that which requires least material to be removed.

It is after said that:-

The best material handling is no material handling


/b>


Aids to good materials handling

There is much attention required to arrive at good material handling.

1. Correct identification of material

The identification of material handling should be correct as the cost and frustration of trying to identify anomy means material becomes very high.

2. Correct packaging of material

The packing/packaging of material should be correct and appropriate to ensure that safety of material. Easily damaged material requires careful handling and costly.

3. Capacity of equipment

The capacity of equipment should be over and above the handling of materials to make economical for heavy single loads and other multiple loads.

4. Size of load

At ways move the largest possible again to avoid multiple handling

5. Weight of container

It is more cut to heavier loads it should be container the load to use lightest the setting ensured of material handling. The MIS should conform to the organizational structure other system and delegation of authority within the company.

The system may work optimum level when timely and relevant are received as taken and

 implemented feedback is necessary for further corrective action.



Effective management system

Now a day’s decision making with

programed MIS/ communication is

 considered to be more effective

 management of system in which

 feedback plays a vital role in achieving

the designed objective/largest. 


System 

- A  system  may be  defined as  a group of inter- related  parts or  elements designed to  achieve  a particular objective.

 - A  system  always exists  within an  environment which  provides  resources as  input into the  system and that accepts outputs of the  system which doing the  process of control. 

- A simplified  system is drawn as. 

System designed 

- The engineering  design  means an  activity of which the  purpose is to fulfil human  related to the entirely technological facture of the outline. 

- This designed  process is an  activity to convert the  resources into system economically  to meet the human  needs. 

- Therefore  system  design  means  utilizing the human efforts  materials machines and finance 

to fulfil the human  needs or wants. 






Needs specifications

When the  needs are a  system  is required to be designed  need  gets the  shape of  system in the 

following shapes. 

1. Need  analysis to  explore  potential  needs Market  research is  conducted for making  needs  analysis for which habits &  behavior of the  people in social  economic  system is  kept in  mind  by  way of systematic  approach  experience and set of techniques.

2. Development of  possible  system 

In order to  develop  a possible  system  various  alternatives  may  involve  different costs & probabilities of  success out  of their  best  possible  system  is selected to  achieve the objectives. 

3. Comparison of  system  needs and proposed  system

When the  fully  developed  system  is selected and  it is  compared with that of  basic  needs or requirements. In case of any  point  noted for correction  it is  further considered. 

4. Review and  modification of  possible  system 

There is  always room for  improvement which  may be made  in order to make the  system simple and streamlined. 

5. Re-valuation and decision 

The modified system is once again revalued it aims to find whether the system is beneficial fulfils all needs and there is no technical social economical and legal problem.

 Salient features of a system

1. It refers what and how things are done.

2. It emphasizes communication structure.

3. It stresses channel 

Systems design for best material handling

 In order to design best system for materials handling some of the important requirement to be considered are as under:-

1. It reduces the handling( i.e. less labor less equipment requirements & less time required for production)

2. It provides continuous flow of materials.

3. It requires less supervision.

4. It requires less space.

5. It reduces delay between were stations.

6. It reduces damages in handling.

7. It reduces labor costs.

8. It reduces in process storage and there by reduces inventories.

9. It provides better production control.

10. It provides better coordination between different departments.

Feasibility

- For set up of a feasible/ viable manufacturing plant location of a plant industry is an

 important arrangement decision which is a two-step decision:-

i. Choice of general area or region.

ii. Choice of site within the area selected.

- Location decision is based on the organization long term strategies such as technological

 marketing resource availability and financial strategies.

- The objective of plant location decision making is to minimize the sum of all costs affected by location.

- Plant location is important because of the following.

i. Location influences plant facilities needed.

ii. Location influences capital investment and operating costs.

- A firm would like to locate the factory in a place where the availability of inputs may be land labor raw material energy transportation and water supply etc. 

After setting up of an industry the total cost of a product manufactured can be calculated as under:







Material handling costs

There are only major functions performed in

 production of a product/item.

i. Processing

The materials under consideration are changed in physical form.

ii. Material handling

Material are brought to move through or removed from the processing activity. The material handling of the portion of the total production cost is substantial and varies from 10-30% depending on the manufacturing items and process if manufacture. Therefore being the major portion of production cost there is a need for calculating material handling cost correct determination of material handling cost is necessary because of the following.

- To help in determining accurate production cost.

- To identify all the material handling cost to exercise effective control so as to minimize the

 handling costs.

- To help in improving methods.

- To help in comparing cost the improved methods are suggested.

- To justify large movements on automation.

- To help in budgeting.

- To provides on basis for comparing handling efficiencies.

Feasibility study for analyzing material handling problems

Following factors should be studied to analysis the material handling problems.

1. Establish the scope of the study.

2. Pin point the areas of plant layout to be covered by the study.

3. Determine volume expected to be handled per unit time by the new system.

4. Nature and type of the materials to be handled.

5. Determine the handling cost of the items being handled by the present system.

6. Determine details of distance to be moved with details of curves slopes etc. 

7. Determine how to move the material in tray bundles pallets etc.

8. Determine the details of the equipment used capacity speed flexibility etc.

9. Determine the time taken for the movement.

10. A thorough survey should then be made considering the systems approach.

11. Alternative system should be evaluated from all angles including financial physical safety acceptance by the management and operators and its effects on working safety and overall environment. 



Coordination of Equipment’s and vendors

- In the past material handling was neglected and due importance was not given to this

 function in the industries. This was simply due to lack of awareness or the part of management.

- But now a days this aspect of material handling is being given its due importance and

 consideration and materials handling engineer’s person play a vital role in the industries.

- In order to carry out the function of coordination of equipment and vendors regarding materials handling the personal of material handling department work in close

coordination/ association with other departments of the industry such as work the following.

1. Purchasing department

To facilitate in deciding the size of order packaging packing and transportation systems from vendor supplier place to the industry.

2. Quality control people

Quality control people check the specified quality of the materials.

3. Store department

Handling and storage of material and supplies is determined by the characteristics of the items and the nature of storage methods.

4. Production control department

Material handling department must cooperate and coordinate with production control depth in following areas:-

i. Directing path of the material movement.

ii. Moving material in lots or containers of pre- determined sizes.

iii. Making optimum use of mechanical handling in picking accumulation and loading.

iv. Meeting production requirement with the handling equipment.

v. Material handling system itself must incorporate features of production control inventory control and accounting.

vi. Moving material as per schedule and to avoid rush deliveries partial load or duplicate moves. 

5. Industrial engineering department

Since material handling function is a division of the broad field of industrial engineering materials handling engineers dealing different function e g.

i. With the process engineering in designing the manufacturing process to establish line balancing in process handling and storage operation.

ii. With the methods engineering in designing the individual work places the method used in performing the operation.

iii. With the work standard personal in establishing work standards for materials handling operations for using as the basis of incentive schemes for material handlers.

iv. With plant layout personal in developing the overall often pattern and the arrangement of the facilities in the plant. 

Introduction to bulk material handling equipment.

- It is the present day need for the equipment’s to handle heavy loads with fast speed reliability safety economy.

- In order to meet the variety of requirements equipment of differents types and size have been develop and are being manufactured.

- Application of material handling devices is a prime consideration in designing new plant and for modifying existing plants.

- These device increase output improve quality speed up the deliveries and therefore decrease the cost of production.

- Material handling are the equipment’s are mechanically, electrically, hydraulically or pneumatically operated or use there combination.

- Material handling equipment’s are not production mechanism.

- There are auxiliary equipment’s which improves the flow of materials which in turn reduce stoppages in production machines and thus increases their production.

- Material handling equipment’s should be able to give maximum efficiency, economy, life and reliability of service under- utilization and faulty selection of the material handling equipment is a expensive which give rise to increase in operating costs.

- The equipment selected should be according to the requirement of the job in respect to size, shape, weight, and material to be handled etc.

- According to George Hageman the important engineering and economic handling installation can be classified as:-

• Factory relating to the plant and operating methods.

• Factory depending on materials or parts handled.

• Factory relating to the handling equipment.

• Financial factors. 






Characteristics of a good material handling equipment’s

A good material handling equipment should have following characteristics:-

1. Material should not be designed in handling.

2. Capable to handle materials in required quantity.

3. Capable of delivery material at desired time.

4. Should be able to deliver goods at right time.

5. Should be safe in operation.

The adoption of a  quality  management  system is a strategic  decision for an  organization  that can help to improve its  overall  performance and  provide  a sound  basis for sustainable  development initiatives.The  potential  benefits to an  organization of  implementing a  quality  management  system  based on this international Standard are:

a) the  ability to  consistently  provide  products and services that meet  customer and applicable statutory and regulatory  requirements;

b) facilitating  opportunities to  enhance customer satisfaction;

c) addressing  risks and  opportunities  associated with its context and objectives;

d) the  ability  to demonstrate conformity to  specified  quality  management  system  requirements.This International Standard  can be  used by  internal and  external parties.It  is not the  intent of this International Standard to  imply the  need for:

— uniformity  in the  structure  of different  quality  management systems;

— alignment of documentation to the clause  structure of this International Standard;

—  the use of the  specific terminology of this International Standard  within the  organization.The  quality  management  system  requirements  specified  in this International Standard are complementary to  requirements for  products and services.This International Standard employs the  process  approach,  which incorporates the Plan-Do-Check-Act 

(PDCA) cycle and risk- based  thinking.The  process  approach  enables an  organization  to plan its  processes and their interactions.The PDCA cycle  enables an  organization to  ensure that its  processes are  adequately resourced and managed, and that  opportunities for  improvement are  determined and acted on.Risk- based  thinking  enables an  organization to  determine the  factors  that could  cause its  processes and its  quality  management  system to deviate from the  planned results,  to put in  place preventive controls to  minimize  negative  effects and to make  maximum use of  opportunities as they arise. Consistently  meeting  requirements and addressing  future  needs and  expectations poses a challenge for  organizations in an  increasingly dynamic and  complex environment. To  achieve this objective, the organization  might  find it  necessary to  adopt  various  forms of  improvement  in addition to correction and  continual  improvement,  such as  breakthrough change, innovation and re- organization.In this International Standard,  the following verbal  forms are used:

— “shall”  indicates a requirement;

— “should”  indicates a recommendation;

— “may”  indicates a permission;

— “can”  indicates a  possibility or a capability.

Information marked as “NOTE” is for  guidance in  understanding or clarifying the  associated requirement. 



0.2 Quality  management  principles

This International Standard is  based  on the  quality  management  principles  described in ISO 9000. The descriptions  include a  statement  of each  principle, a  rationale of why the  principle is  important for the organization,  some examples of  benefits  associated with the  principle and examples of  typical actions to improve the  organization’s  performance  when  applying the  principle.The  quality  management  principles are:

—  customer  focus;

— leadership;

— engagement of people;

—  process  approach;

—  improvement;

— evidence- based  decision making;

—  relationship  management.



0. 3 Process  approach

0. 3.1 General

This International Standard promotes the adoption of a  process  approach  when developing, implementing and  improving the effectiveness of a  quality  management  system, to  enhance  customer  satisfaction  by  meeting  customer  requirements. Specific  requirements  considered  essential to the adoption of a  process  approach are  included in Understanding and  managing interrelated  processes as a  system contributes to the  organization’s effectiveness and  efficiency in  achieving its  intended  results. This  approach  enables the  organization to control the interrelationships and interdependencies  among the  processes of the  system,  so that the 

 overall  performance of the  organization  can be enhanced.The  process  approach  involves the systematic definition and  management of  processes, and their interactions,  so as to  achieve the  intended  results  in accordance with the  quality  policy and strategic direction of the  organization. Management of the  processes and the  system as  a whole  can be achieved using the PDCA cycle with an  overall  focus on risk- based  thinking  aimed at taking advantage of  opportunities and  preventing  undesirable  results.The  application of the  process  approach in a  quality  management  system  enables:

a)  understanding and consistency in  meeting  requirements;

b) the  consideration of  processes in  terms of  added value;

c) the  achievement of  effective  process  performance;

d)  improvement of  processes  based on  evaluation of  data and information.

Figure 1  gives a schematic  representation of any  process and  shows the  interaction of its elements. The monitoring and measuring  check points,  which are  necessary for control, are  specific to  each  process  and will  vary  depending  on the  related risks.




0.3.2 Plan-Do-Check-Act cycle

The PDCA cycle can be applied to all processes and to the quality management system as a whole. 

Figure 2 illustrates how Clauses 4 to 10 can be grouped in relation to the PDCA cycle.


NOTE Numbers in brackets refer to the clauses in this International Standard.

Figure 2 — Representation of the structure of this International Standard in the PDCA cycle

The PDCA cycle can be briefly described as follows:

Plan: establish the objectives of the system and its processes, and the resources needed to deliver results in accordance with customers’ requirements and the organization’s policies, and identify and address risks and opportunities;

Do: implement what was planned;

Check: monitor and ( where applicable) measure processes and the resulting products and services against policies, objectives, requirements and planned activities, and report the results;

Act: take actions to improve performance, as necessary.

0. 3. 3 Risk- based thinking

Risk- based thinking (see Clause A. 4) is essential for achieving an effective quality management system.The concept of risk- based thinking has been implicit in previous editions of this International Standard including, for example, carrying out preventive action to eliminate potential nonconformities, analysing any nonconformities that do occur, and taking action to prevent recurrence that is appropriate for the effects of the nonconformity. To conform to the requirements of this International Standard, an organization needs to plan and

 implement actions to address risks and opportunities. Addressing both risks and opportunities establishes a basis for increasing the effectiveness of the quality management system, achieving improved results and preventing negative effects.Opportunities can arise as a result of a situation favourable to achieving an intended result, for example, a set of circumstances that allow the organization to attract customers, develop new products and services, reduce waste or improve productivity. Actions to address opportunities can also include consideration of associated risks. Risk is the effect of uncertainty and any such uncertainty can have positive or negative effects. A positive deviation arising from a risk can provide an opportunity, but not all positive effects of risk result in opportunities.



0. 4 Relationship with other management system standards

This International Standard applies the framework developed by ISO to improve alignment among its International Standards for management systems (see Clause A.1).

This International Standard enables an organization to use the process approach, coupled with the PDCA cycle and risk- based thinking, to align or integrate its quality management system with the requirements of other management system standards.This International Standard relates to ISO 9000 and ISO 9004 as follows:

— ISO 9000 Quality management systems

 — Fundamentals and vocabulary provides essential

 background for the proper understanding and implementation of this International Standard;

— ISO 9004 Managing for the sustained success of an organization 

— A quality management approach

 provides guidance for organizations that choose to progress beyond the requirements of this International Standard. Annex B provides details of other International Standards on quality management and quality

 management systems that have been developed by ISO/TC 176. This International Standard does not include requirements specific to other management systems, such as those for environmental management, occupational health and safety management, or

 financial management. Sector- specific quality management system standards based on the requirements of this International Standard have been developed for a number of sectors. Some of these standards specify additional

 quality management system requirements, while others are limited to providing guidance to the application of this International Standard within the particular sector.
