MATERIAL HANDLING
Material Handling is an integral part of production
process.
 Material Handling involves piling, loading, unloading
and transporting parts or raw materials from place to
another within a Industry.
 Material Handling involves the handling of materials
manually or mechanically in batches or one item at a
time within the plant.
 The material movement may be horizontal, vertical or
the combination of horizontal and vertical.
Functions of Material Handling
 Movement and positioning of the purchased materials, tools,
spares, etc for the purpose of storage.
 Transportation of materials from stores to shops or
departments.
 Movement of materials from stores to shops or departments
from one machine to one machine to another and from one
department to another.
 Movement and positioning of finished products or
components for the purpose of stocking or sale.
 Unloading raw materials from trucks or other transport.
 Loading packed materials on motor trucks or other transport.
Objective of Material Handling
 Material handling focuses on the need of installing
efficient and safe and economical methods and
equipments for handing materials.
 Material handling equipment is not a production
machinery, but it is an auxiliary equipment that
improves flow of material within an Industry.
Factors to be considered in Material Handling
Process:
 Engineering factor
 Economic factor
Engineering Factors considered in Material Handling:
 Nature of materials and products to be handled.
 Production process and equipments.
 Building construction.
 Layout.
 The existing material handling equipment.
 Production Planning and Control.
 Packaging.
Economic Factors to be considered in Material
Handling:
Initial cost of equipment
 Cost of Installation.
 Rearrangement of present equipment
 Cost of maintenance, repairs, supplies, etc.
 Cost of power and depreciation.
 Cost of Labour to operate.
 Cost of any necessary auxiliary equipment.
 Saving the equipment will bring about indirect cost,
space required.
Principles of Material Handling:
 Reduction in Handling
 Reduction in Time
 Principal of Unit Load
 Use of Gravity
 Safety
 Use of Containers
 Stand by facility
 Periodical Check up
 Avoid Interference with production line
 Flexibility
1. Reduction in Handling:
 The first principle of material handling is to
minimize the material the material handling as far
as possible.
 The material should be moved as far as possible.
 Layout improvement or changes in the process may
make it possible to reduce material handling.
Principles of Material Handling:
2. Reduction in time:
 Time is money.
 Time lost means paying wages to the workers when they
are not doing productive work.
 Time lost reduces the rate of output and increases unit
overhead cost.
 Therefore the time of each movement or material
handling should be minimized.
Time is wasted principally in three things:
 Waiting
 Loading and Unloading
 Travel
Principles of Material Handling:
3. Principle of Unit Load:
 The principle of “ Unit Load “ should be applied.
 According to principle of “Unit Load”, the materials
should be moved in lots rather than on individual
basis.
 Optimum number of pieces should be moved in one
unit to utilize the material handling equipments
effecti9vely.
Principles of Material Handling:
4. Use of Gravity:
Whenever possible, utilize gravity for assisting material
movements as it is the cheapest source of motive
power.
5. Safety: Safe, Standard, efficient, appropriate and
flexible material handling equipment should be
used.
6. Use of Containers:
Design containers, pallets, drums etc, to reduce the
cost of handling and damage of material in
transport.
Principles of Material Handling:
7. Stand by facility:
The provision of stand by facilities should be made so
that the sudden break down may not stop the
operations due to non- availability of materials.
8. Periodical Check up :
The check up repairing and maintenance of the existing
material handling equipments should be made
periodically.
9. Avoid interference with production line:
The material handling services should not interfere with
the production line.
Principles of Material Handling:
10. Flexibility:
The material handling services should be evaluated
periodically and necessary changes should be
incorporated where ever it is possible.
