This document defines material handling and discusses the key aspects of material handling systems. It begins by defining material handling as the art and science of moving, storing, protecting, controlling and tracking materials. It then discusses the main functions of material handling - moving, storing, protecting, controlling and tracking the status of materials. The document also provides definitions and examples of different classes of materials, including raw materials, purchased parts, in-progress materials, and finished materials. It discusses principles of effective material handling and categories of material handling equipment, such as containers, transport equipment, storage and retrieval equipment, and automatic data collection systems. Specific types of equipment like conveyors, industrial vehicles, cranes and hoists are also described

2. Definitions:
•Material handling is the art and science of moving, storing, protecting,
controlling and status of material
 Moving: Is required to create time and place utility.The value of
having the material at the right time and the right place.
 Storing: Provides a buffer between operations, facilitates the
efficient use of people and machines.
 Protecting: Includes the packaging,damage and theft.
 Controlling: Physical storage, sequence and space between
material.
 Status: Real-time awareness of the location, amount, destination
and schedule of material.

3. Material Handling is the function of moving the right material to
the right place at the right time, in the right amount, in right
sequence, and in the right condition to minimize production cost.
The cost of MH estimates 20-25% of total manufacturing labor
cost in the United States [The Material Handling Industry of
America (MHIA)]

4. Classes of materials
• Raw materials:- This is material which is used in product
manufacturing and is in an unprocessed condition.(eg cotton)
• Purchased Parts:- These are the items used in the assembly of
the product.(eg processor)
• In-progress materials:- They are called ‘work in progress’
inventories. These goods require further processing.
4

5. Finished materials:- These are fully manufactured goods,
inspected and ready for delivery to the customers.
Supplies:- These are consumable goods used in the process of
manufacturing.(eg electricity)

6. • Least handling is the best handling.
• Lengths and number of moves to be minimized.
• Unit load
• Minimize the distance.
Principles of material handling

7. • The design of the container. e.g. shippers are used for
storing finished bulk. & for raw materials as per the
property of materials they are stored- plastic containers
( light weight containers)
• Re-handling and back tracking of the materials should be
avoided.
• The materials handling service should not interfere with
the production flow.

Monorails, Hoists and Cranes

16. Maintenance strategies
for hoists and cranes:
Portable crane
• It is necessary to keep loads within design limits on
portable cranes that are mounted on wheels platforms.
• Frequent inspection of brakes, load hoisting and lowering
mechanism
• Inspection of boom, base and platform for any sign of
stress
Eg: cracks, bends, breaks
16

17. Over head cranes:
• Keep the attachments in overhead cranes loaded within the
rating capacity.
• Maintain safety factors for replacement parts according to
manufacturer specifications
• Check welded connections for cracks, bends abrasion and
corrosion Maintenance strategies for conveyers:
• Conveyer system need to be inspected on a regular basis. The
important areas include rollers, bearings chains and belts. All
of these moving parts are subjected to wear and tear
• Check conveyers to detect any bolt slippage, dragging or
defective rollers.
• Moving equipment parts are subjected to breaks caused by
metal fatigue, loose bearing and obstructions.

18. A typical scheduled
conveyor maintenance plan:
Check/lubricate all bearings, universal joints, and pulleys.
i. Check chain tension, wear and lubricate
ii. Check sprocket alignment, wear and screw set.
iii. Check flat belt tension, wear and acing
iv. Check V-belt tension, wear and sheave alignment.
v. Check general condition of system
vi. Operate entire system after service
vii. List any items requiring replacement or repair.
