Material Handling Equipment MHE

 

Contents

Material handling equipment (MHE) is used for the movement and storage of material within a facility or at a site. MHE can be classified into the following five major categories:

  • Transport Equipment.

  • Positioning Equipment.

  • Unit Load Formation Equipment.

  • Storage Equipment.

  • Identification and Control Equipment.

2.1 Conveyors

  • Conveyors are used to move materials over a fixed path

  • Gravity or Powered devices generally used when:

  1. Loads are unifrom

  2. Materials move continuously

  3. Route does not vary

  4. Load is constant

  5. movement rate is relatively fixed

  6. Conveyors can by-pass cross traffic

  7. Path to be followed is fixed

  8. Movement is form one fixed point to another fixed point.

  • The major types of conveyors are:

 

1. Chute conveyor 

11. Screw conveyor 

 

2. Wheel conveyor 

12. Pneumatic conveyor 

 

3. Roller conveyor 

13. Vertical conveyor 

 

4. Chain conveyor 

14. Cart-on-track conveyor 

 

5. Slat conveyor 

15. Tow conveyor 

 

6. Flat belt conveyor 

16. Trolley conveyor 

 

7. Magnetic belt conveyor 

17. Power-and-free conveyor 

 

8. Troughed belt conveyor 

18. Monorail 

 

9. Bucket conveyor 

19. Sortation conveyor

 

10. Vibrating conveyor

2.2 Cranes and Hoists

  • Overhead devices used within an area fixed by the supporting and guiding rails

  • They are usually used when:

  1. Movement is within a fixed area.

  2. Moves are intermittent

  3. Loads vary in size or weight

  4. Cross Traffic would interfere with conveyors

  5. Units Handled are not unifrom

  • The major types of cranes are:

    1. Jib crane

    2. Bridge crane

    3. Gantry crane

    4. Stacker crane

2.3 Industrial Trucks

  • Hand or powered vehicles their primary function is maneuvering or transporting.

  • They are generally used when

  1. Moves are intermittent

  2. Movement is over varying routes.

  3. Loads are unifrom or mixed in size or weight

  4. Cross Traffic would prohibit conveyors

  5. Need clear and suitable running surface

  6. Most of the operations are handling

  7. Material can be put into unit loads

  • The major types of Industrial Trucks are:

  1. Hand truck

  2. Pallet jack

  3. Walkie stacker

  4. Pallet truck

  5. Platform truck

  6. Counterbalanced lift truck

  7. Narrow-aisle straddle truck

  8. Narrow-aisle reach truck

  9. Turret truck

  10. Order picker

  11. Side-loader

  12. Tractor-trailer

  13. Personnel and burden carrier

  14. Automatic guided vehicle (AGV)

  •  Equipment used to handle material at a single location so that it is in the correct position for subsequent handling, machining, transport, or storage.

  • Unlike transport equipment, positioning equipment is usually used for handling at a single workplace.

  • Material can also be positioned manually using no equipment.

 

  • Equipment used to restrict materials so that they maintain their integrity when handled a single load during transport and for storage.

  • If materials are self-restraining (e.g., a single part or interlocking parts), then they can be formed into a unit load with no equipment.

  •  Equipment used to collect and communicate the information that is used to coordinate the flow of materials within a facility and between a facility and its suppliers and customers.

  • The identification of materials and associated control can be performed manually with no specialized equipment.
