5. Scope of
Material Handling
There are three perspectives about material
handling.
™The traditional point of view:Emphasis is on
material movement from one Location to another
within the confines of individual plant
™Plant wide concern:focuses on overall flow of
material.
™The system point of view:Requires visualization
of materials handling problem,the physical
distribution activities as a one encompassing
system.

Material Handling
Material Handling
™Material handling is an important part of factory and
industrial processes. It covers the entire spectrum of
functions such as waste handling, assembly line
management, storage and material transport.
™A material handling system includes several smaller
components that work side by side, to make the everyday
business more efficient and cost effective.
™New advances in technology have revamped the entire
material handling system and function. Robotics and
automation techniques are increasingly becoming prevalent.
™ If you have an existing business, consider hiring a
consultant, to set up your material handling processes.

15. Material Handling Costs
Material Handling Costs
The costs of material handling arises from two sources
™The cost of owning & maintaining the equipment.
™Cost of operating System
Every effort should be made to how to reduce the
material handling cost.There are three functional ways:
1.Eliminating handling itself,where ever & whenever
possible
2.Mechanizing largely by conveyors power driven trucks.
3.Making the necessary handling more efficient
16. Material Handling Costs
Material Handling Costs
•Unit load - number of items or bulk
material arranged so they can be picked
up and delivered as one load
•Large or small?
•If large, cost/unit handled decreases
•But, depending upon
–cost of unitizing, de-unitizing
17. Material Handling Costs
Material Handling Costs
–space required for material handling

26. Material Handling Methods
Material Handling Methods
1. Inspect materials for slivers, jagged edges, burrs, rough
or slippery surfaces.
2. Get a firm grip on the object.
3. Keep fingers away from pinch points, especially when
setting down materials.
4. When handling lumber, pipe or other long objects, keep
hands away from the ends to prevent them from being
pinched.
5. Wipe off greasy, wet, slippery or dirty objects before
trying to handle them.
6. Keep hands free of oil and grease.

Material Handling Methods
Lifting and Carrying
Before employees are assigned to jobs requiring heavy
and/or frequent lifting, make sure they are physically suited
for the job.
If a load is thought to be more than one employee can
handle, assign two employees to the operation or supply
materials handling equipment. Instruct employees in proper
ways to lift.
Proper Way To Lift
Here are six steps to safe lifting:
•Keep feet apart - one alongside, one behind the object;
•Keep back straight, nearly vertical; bend at the knees
instead of the waist;
28. Material Handling Methods
Material Handling Methods
1. Tuck your chin in;
2. Grip the object with the whole hand;
3. Tuck elbows and arms in;
4. Keep body weight directly over feet
When bulky objects are to be handled or when objects are to
be carried on the shoulder, employees shall be trained in
these techniques for special situations.
Handling Barrels and Drums
Whenever possible, use a dolly or other mechanical device
when moving barrels or drums.
If two employees are assigned to up-end a full drum, they
should use the following procedures:
29. Material Handling Methods
Material Handling Methods
1. Stand on opposite sides of the drum and face each other;
2. Grasp both chimes (rolled edges at both ends of the
barrel) near their high points, lift one end; press down on
the other;
3. As the drum is up-ended and brought to balance on the
bottom chime, release the grip on the bottom chime and
straighten the drum.
When two employees are to overturn a full drum, they
should use this procedure:
1. Make sure there is enough room. Cramped quarters can
result in badly injured hands.
30. Material Handling Methods
Material Handling Methods
1. Both stand near each other, facing the drum.
Grip the closest point of the top chime with both
hands, resting palms against the side of the
drum, push until the drum balances on the lower
chime.
2. Step forward a short distance, and each
employee releases one hand from the top chime
in order to grip the bottom chime. They ease the
drum down to a horizontal position until it rests
solidly on its side.
