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.

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

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

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
