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