MeaningMaterial handling is the art and science involving themovement, packing, and storing of substances in any

form

- American Material SocietyMaterial Handlingis the movement, storage, control

and protection of materials, goods and products

throughout the process of manufacturing, distribution,

consumption and disposal. The focus is on themethods, mechanical equipment, systems and related

controls used to achieve these functions.

Material Handling Creation of time and place utility

Movement and storage of material at the lowest

possible cost through the use of proper methods andequipments.

Lifting, shifting and placing of materials which effect asaving in money, time and place

Art and science of conveying, elevating, positioning,transporting, packing and storing of materials

Importance of M H Efficient material handling is important to

manufacturing operations. Materials sent by vendorsmust be unloaded, moved through inspections adproduction operations to stores and finally to theshipping department.

These movements do not add value to the product but

they do add value to the cost

Material handling analysis is a subset of plant layout.Method study, plant layout and material handling areall part of the design of a production facility

Material handling systems and plant layout enhanceeffectiveness of each other.

Efficient operation of appropriate material handling

methods reduce cost and enables maximumcapabilities to be derived from a given productionfacility

Improved working conditions and greater safety inmovement of materials

Contribute to better quality by avoiding damage toproducts by inefficient handling

Increased storage capacity through better utilization ofstorage areas

Higher productivity at lower manufacturing cost

M H Principles Eliminate handling If not, make handling distance as short as possible

Keep moving If not, reduce the time spent at terminal points to route as short as

possible

Use simple patterns of material flow The simplest path is a straight line, if not, avoid back tracking, cross

over's

Carry pay loads both ways If not, minimize time spent on transport empty by changing speed in

return route Carry full load

If not, decrease carrying capacity by lowering the speed

Use gravity If not, use a cheaper power source

Organization & Material Handling The structure varies with industry, type of

manufacturing process, the product manufactured, its

bulk and its value.

In small firms, it may be one of the functions assigned

to the plant engineer, purchasing manager or

production manager.

Big firms, a separate dep. Itself is deve3loped to studyprocessing and devise better handling techniques.

When thus organized, they form part of industrial

engineering division.

Unit load concept Unit load is the number of items, or bulk material, so

arranged that the mass can be picked up and moved as

a single object, too large for manual handling.

Flow Pattern When drawn on a paper, the flow pattern becomes a

flow chart, which will help locate needless criss-

crossing and back tracking of material movements.

Once unwanted movements are known, steps can be

taken to eliminate or reduce such move.

Advantages of good flow patterns Increased efficiency of production

Better utilization of floor space

Simplified handling activities

Better equipment utilization, less idle time Reduced in-process time

Reduced in-process inventory

More efficient utilization of work force

Reduced walking distance

Minimal accident hazards

Basis for an efficient layout

Faster supervision


14/19

Minimal back tracking

Smooth production flow

Improved scheduling process

Reduced crowded conditions

Better house keeping

Logical work sequencing

Factors affecting selection of M H

Equipments Production Problems

Volume of production, class of material, layout of plant

Capabilities of handling equipment available Adaptability, flexibility, load capacity, power, speed,

space requirement, supervision requirement, ease of

maintenance, environment, cost.

The human element involved Safety

Types of material handling

Equipments Conveyors

Belt conveyors, Chain conveyors, Roller conveyors,

Pneumatic conveyors, Bucket conveyors, Screw

conveyors, Pipeline conveyors, Vibratory conveyors,

Chute or Gravity conveyors


17/19

Cranes, Elevators and Hoists

Cranes- overhead rails or ground rails or wheels Elevators .between flowers- vertically

Hoist vertically, horizontally limited area- electric or

chain hoist.

Industrial Trucks


18/19

Miscellaneous Handling

Equipments Pipeline

Automatic transfer device

Automatic Guided Vehicle No operators, flexibility in paths, signals through wires

on floor. A remote control computer reqd.

Industrial Robots

Built in control- can be programmed- hence veryversatile
