2. Definition and Scope of Materials Handling
• Materials handling is loading, moving and unloading of materials. To
do it safely and economically.
• Materials handling is the art and science involving the moving,
packaging and storing of substances in any form.
• Purpose or essential requirements of a good materials handling
system may be summarized as:
• Efficient and safe movement of materials to the desired place.
• Timely movement of the materials when needed.
• Supply of materials at the desired rate.
• Storing of materials utilizing minimum space.
• Lowest cost solution to the materials handling activities.
3. Definition and Scope of Materials Handling
• Functional scope of materials handling within an industry covers the
following:
• Bulk materials as well as unit materials handling. Bulk handling is particularly
relevant in the processing, mining and construction industries. Unit materials
handling covers handling of formed materials in the initial, intermediate and
final stages of manufacture.
• Industrial packaging of in-process materials, semi finished or finished goods,
primarily from the point of view of ease and safety of handling, storage and
transportation.
• Handling of materials for storage or warehousing from raw materials to
finished product stage.
4. Importance of Materials Handling
• The importance of materials handling is that it helps productivity and
thereby increases profitability of an industry.
• A well designed materials handling system attempts to achieve the
following:
• Improve efficiency of a production system by ensuring the right quantity of materials
delivered at the right place at the right time most economically.
• Cut down indirect labor cost.
• Reduce damage of materials during storage and movement.
• Maximize space utilization by proper storage of materials and thereby reduce storage
and handling cost.
• Minimize accident during materials handling.
• Reduce overall cost by improving materials handling.
• Improve customer services by supplying materials in a manner convenient for
handlings.
5. Negative Aspect of Materials Handling
• Additional capital cost involved in any materials handling system.
• Once a materials handling system get implemented, flexibility for
further changes gets greatly reduced.
• With an integrated materials handling system installed,
failure/stoppage in any portion of it leads to increased downtime of
the production system.
• Materials handling system needs maintenance, hence any addition to
materials handling means additional maintenance facilities and costs.
6. Principles of Materials Handling
• Planning Principle - This is the most basic principle which is in line
with the Materials Handling
• Consider the plant layout before equipment / system design.
• Plan correct location for materials supply and disposal. Plan for scrap removal.
• Assure adequate storage space at the workplace.
• Avoid placing materials directly on the floor. Place product on a pallet, skid
etc. at the beginning of the process.
• Use same container throughout the materials movement, as far as
practicable.
• Observe principles of motions economy.
• Plan productive operations and inspections during material movement, if
possible.
7. Principles of Materials Handling
• Materials Flow Principle - Plan operations sequence and equipment
arrangement to optimize material flow.
• Eliminate obstacles from material flow.
• Plan material movement in a direct path (avoid backtracking, zig-zag
movements etc.)
• Use product layout whenever possible.
• Keep related work areas close together.
• Combine operations to reduce material movement.
• Minimize movement between floors.
• Move bulky / weighty materials the least distance.
• Process heavy / bulky materials close to receiving.
8. Principles of Materials Handling
• Gravity Principle- Utilize gravity to move material whenever
practicable.
• Use roller conveyors, slides, chutes between equipment/processes.
• Use ramps between varying work or floor levels.
• Use sloping floor when materials movement by hand truck is mainly in one
direction.
• Use spiral chutes to feed machines at different floors.
Editor's Notes
The planning starts with the question ‘‘why’’ at all the contemplated materials handling is needed? If the necessity is clearly established then only a new handling system is to be considered. Next question is ‘‘what’’ type of materials to be moved to ‘‘where’’ and ‘‘when’’ ? Answer to this question leads to the method to be deployed i.e. ‘‘How’’ and by ‘‘whom’’ (manpower/operator) the materials handling will be effected. In effect, the equation emphasizes the necessity of carefully analyzing both the MATERIALS to be handled and MOVES to be made before selecting the METHODS.
