MATERIAL HANDLING AND STORAGE SYSTEM[1]

Defined as the art and science of moving, packing and storing of substances in any form.

Also MH and Storage is the efficient short-distance movement of goods that usually takes place within the confines of a building such as a plant or a warehouse or between a building and a transportation agency.

OBJECTIVES[1][2]

Main objective is to reduce the number of units as well as the overall cost of material handling and equipment and reducing the distances through which the materials are handled or storage.

The other objectives:- To provide better control of the flow of materials. Lower unit material handling and storage costs. Improved working conditions and greater safety in

movement of materials.

IMPORTANCE OF MATERIAL HANDLING AND STORAGE SYSTEM[2][3]

Material Handling and storage are increases effectiveness of in plant layout by reducing the cost.

These movements do not add value to the product but they do add value to the cost.

Function of production control.Concerned with scheduling of production

control.

Factors affecting the Selection of Materials Handling& Storage Equipment

TYPES OF MATERIAL HANDLING AND ITS EQUIPMENTS[4]

1. Equipments oriented systems a) Convey or Systemsb) Fork lift truck c) Industrial truck system

2. Material Oriented Systemsd) Unit handling systeme) Bulk handling systemf) Liquid handling system

EquipmentsConveyors

◦ Belt conveyors, Chain conveyors, Roller conveyors, bucket conveyors, screw conveyors, pipeline conveyors, vibratory conveyors, chute or gravity conveyors.

Cranes, Elevators and Hoists◦ Cranes – overhead rails or ground rails or

wheels◦ Elevators – between floors – vertically◦ Hoists - vertically, horizontally – limited area –

electric or chain hoist

Belt Conveyor- Motor driven belt usually made of metal fabric

Chain Conveyor- Motor driven chain that drags material along a metal side base.

Roller Conveyor- Boxes , large parts or units loads roll on top of a series of rollers mounted on a rigid frame.

These are overhead devices used for moving varying loads intermittently between points within an area.

2. Cranes, Elevators and Hoists

Cranes – Devices mounted on overheard rail or ground wheels or rails .They lift, swing and transport large and heavy materials

Elevators – Types of cranes that lift materials –usually between floors or buildings

Hoists- Move vertically or horizontally. May be air hoist , electric hoist, chain hoist

Fort lift Truck

Pallet truck

TYPE OF STORAGE SYSTEM AND ITS EQUIPMENTS[4]

Automated storage and retrieval system(ASRS or AS/RS):-

An automated storage and retrieval system (ASRS or AS/RS)

consists of a variety of computer-controlled methods for

automatically placing and retrieving loads from specific storage

locations.

An automated storage/retrieval system (AS/RS) is a storage system

that performs storage and retrieval operations with speed and

accuracy under a defined degree of automation.

Equipments

Products such as pallet racking, shelving, carts, etc. belong to storage.

A pallet is the structural foundation of a unit load which allows handling and storage efficiencies.

HOUSEKEEPINGStorage areas must be kept free from accumulation of

materials that create hazards from:

◦ Tripping

◦ Fire

◦ Explosion

◦ Pest harborage

ESSENTIAL OF GOOD MATERIAL HANDLING OR STORAGE SYSTEM[1][2]

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.

DISPOSAL OF WAST MATERIAL[5]

An enclosed chute must be used

when dropping material more than

20 feet outside of a building.

When debris is dropped through

holes in floors without the use of

chutes.

Area must be enclosed with

barricades.

Warning signs must be posted at

each level.

ENVIRONMENTAL CONDITIONS[6]
