Introduction
Material handling operations involve raw material movements, work-in-process, subassemblies, finished products, tools, and other support materials from one point to another in the plant
Principles of material handling
To minimize the movement of material in the production.
To use the principle of containerization, unit load or palletisation and move optimum number of pieces at a time.
To make use of mechanical devices and reduce manual work.
To ensure safe, effective and flexible material handling.
To arrange material and material handling devices in a manner, not to disturb the production activities.
To make use of gravity forces for material movement, wherever possible.
To ensure movement of the material without damage.
To maintain the material handling devices in good working condition and maximum use of them.
Selection of material handling equipment
1. Type of material:
2. Plant layout:
3. Type of production:
4. Type of production machines:
5. Type of material flow:
6. The other factors:
Types of material handling equipments:

Conveyors
The general characteristics of conveyor systems are as follows:
They are generally mechanized and can be automated in CIM plants.
They have fixed positions, but the path can be straight or Zig zag.
They can be either floor or overhead mounted
Usually they are limited to a one directional flow
They are generally designed to move discrete loads, bulk loads or continuous loads.
They can be either delivery only or delivery plus storage types.
