CHAPTER 1
Introduction to Material Handling
 What is material handling (MH)?
 Do you think material handling can
add value on the final product?
 What will be the impact of material
handling on the productivity of a
plant?
 What is the relationship between
material handling and plant layout?
1. Introduction to Material Handling (MH)
•
Material handling is the combination of art and
science of:
 moving
 storing
 handling
 placing and positioning
• Thus the function includes every consideration
of the product except the actual processing
operation.

1. Introduction to MH…
Material handling means providing the
 right amount
 of the right material
 in the right condition
 at the right place
 in the right position
 in the right sequence
 in the right time
 for the right price
 by the right method
1. Introduction to MH…
In a typical manufacturing facility:
• It has been estimated that average material handling
cost is roughly 20 to 60% of the total production
cost.
• 25% of the work-force is used in material handling.
• 55% of the factory floor is reserved for it.
• 85% of the production time
• It, thus, becomes clear that the cost of production of
an item can be lowered considerably by making a
saving in the material handling cost.
1. Introduction to MH…
• Material handling involves the movements of
materials, manually or mechanically in batches
or one item at a time within the plant.
• The movement may be horizontal, vertical or
the combination of horizontal and vertical.
• Material handling emphasizes upon the need of
installing efficient and safe methods and
equipment for material handling.
• It has been found that 35 to 40% of the plant
accidents are the results of bad methods of
material handling.
1. Introduction to MH…
Advantages of Good Material Handling Systems
 It reduces the time required for handling the
materials
 Reduction in material handling & indirect labor
cost.
 Improvement on productivity
 Better usage of floor space & facility
 Least fatigue to the worker
 Improved work environment
 Reduction in bottle necks
1. Advantages of Good MHS…
 Improvement in safety & reduction in accidents.
 Improved material flow ( Less back tracking).
 It promotes a protected and clean material
handling without any difficulty.
 It eliminates the idle time of workers and
machines.
 Increases the flow rate of materials from one
workstation to another.
 Compact and better stocking of materials in good
location available in the plant.
1. Introduction to MH…
Relationship between Material Handling and
Plant Layout
• There is a close relationship between plant layout
and material handling.
• A good layout ensures minimum material handling
and eliminates rehandling in the following ways:
1. Material movement does not add any value to the
product. a good layout minimizes handling. This
is possible only through the systematic plant
layout.
1. Introduction to MH…
2. The productive time of workers will go without
production if they are required to travel long
distance to get the material tools, etc.
• Thus a good layout ensures minimum travel for
workman thus enhancing the production time
and eliminating the hunting time and travelling
time.
3. Space is an important criterion. Plant layout
integrates all the movements of men, material
through a well-designed layout with material
handling system.
1. Introduction to MH…
4. Good plant layout helps in building efficient
material handling system.
• It helps to keep material handling shorter,
faster and economical.
5. A good layout reduces the material
backtracking,
unnecessary
workmen
movement
ensuring
effectiveness
in
manufacturing.
• Thus a good layout always ensures minimum
material handling.
1.1. Objectives of Material Handling
• Following are the objectives of material
handling:
1. Minimize cost of material handling.
2. Minimize delays and interruptions by making
available the materials at the point of use, at
right quantity and at right time.
3. Increase the productive capacity of the
production facilities by effective utilization of
capacity and enhancing productivity.
1.1. Objectives of Material Handling…
4. Safety in material handling
improvement in working condition.
through
5. Maximum utilization of material handling
equipment.
6. Prevention of damages to materials.
7. Lower investment in process inventory.
