Material Handling Systems

For exploiting productivity potential in logistics


2/22

To understand:

Role of material handling in logistics

Types of material handling systems and their features

Selection criteria for material handling systems and equipment

Learning objectives are:


3/22

Unloading the incoming material from transport vehicle,

Moving the unloaded material to assigned storage place in the

warehouse,

Lifting the material from storage place during order picking,

Moving material for inspection and packing,

Loading the boxes/cartons on the transport vehicle.

Material Handling Stages


4/22

Standard equipment should be preferred to keep low capitalinvestments,

Equipment designed for maximum continuous flow should be preferred,

Portable or movable equipment to be preferred ,

Ratio of dead weight to pay load should be minimum for handling

equipment,

Gravity flow should be incorporated in the system design.

Block Storage


18/22

AdvantagesSimplest system

No investment

Stacking on platform or floor

Wide variety of products can be stored

Disadvantages

Limitation on stack height

Storage Methods

Rack storage


20/22

Load Unitization

The unit load is constructed by bringing together large number of

individual items of identical configuration, so as to make a largeload, which ensures convenience during storage, handling and

transportation.

Pallet storage


21/22

Advantages

Helps in optimum utilization of storage spaceIncreases stability of products during transportation

Lower handling cost due to unitizing

Increases speed of material flow

Reduces frequency of material handling

Facilitates handling loads with machines

Disadvantages

Does not give compete protection to product from environmental

effects
