Presentation Transcript

  1. Material Handling • Material handling is the function of moving the right material to the right place in the right time, in the right amount, in 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)]

  2. Goals of Material Handling • The primary goal is to reduce unit costs of production • Maintain or improve product quality, reduce damage of materials • Promote safety and improve working conditions • Promote productivity • material should flow in a straight line • use gravity! It is free power • move more material at one time • mechanize material handling • automate material handling

  3. Goals of Material Handling • Promote increased use of facilities • Reduce tare weight (dead weight) • Control inventory

  4. Overview of Material Handling Equipment • Material handling equipment includes: • Transport Equipment: industrial trucks, Automated Guided vehicles (AGVs), monorails, conveyors, cranes and hoists. • Storage Systems: bulk storage, rack systems, shelving and bins, drawer storage, automated storage systems. • Unitizing Equipment: palletizers • Identification and Tracking systems

  5. Considerations in Material Handling System Design 1. Material Characteristics

  6. Considerations …cont. 2. Flow rate Quantity of material moved Conveyors Conveyors AGV train High Manual handling Hand trucks Powered trucks Unit load AGV Low Short Long Move Distance

  7. Considerations …cont. 3. Plant Layout

  8. Between fixed points over a fixed path • Belt conveyor • Roller conveyor • Chute conveyor • Slat conveyor • Screw conveyor • Chain conveyor • Overhead monorail conveyor • Trolley conveyor • Wheel conveyor • Tow conveyor • Bucket conveyor • Cart-on-track conveyor • Pneumatic tube conveyor Material Handling Equipment

  9. Over limited areas • Hoists • Overhead cranes • Hydraulic scissors lift • Over large areas • Handcart/truck • Tier platform truck • Hand lift truck / pallet jack • Power-driven hand truck • Power-driven platform truck • Forklift truck • Narrow aisle truck • Tractor-trailer truck • Material lift • Drum truck • Drum lifter • Dolly • Automated guided vehicle system Material Handling Equipment
