Material handling principles & equipments
- 1. MATERIAL HANDLING:EQUUIPMENTS & PRINCIPLES 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.
- 3. • Material handling is a means by which: – Total manufacturing costs are reduced through • Reduced inventory • Improved safety • Reduced pilferage • Improved material control. – Manufacturing quality is improved by: • Reducing inventory • Reducing damage – Any production strategy is executed.
- 5. 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
- 6. CONTD….. • Promote increased use of facilities • Reduce tare weight (dead weight) • Control inventory
- 7. 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
- 8. Categories of Material Handling Equipment 1. Containers and Unitizing Equipment • Containers • Unitizers 2. Material Transport Equipment • Conveyors • Industrial Vehicles • Monorails, Hoists, and Cranes 3. Storage and Retrieval Equipment • Unit Load Storage and Retrieval • Unit Load Storage Equipment • Unit Load Retrieval Equipment • Small Load Storage and Retrieval 4. Automatic Data Collection and Communication Equipment • Automatic Identification and Recognition • Automatic Paperless Communication
- 9. Considerations in Material Handling System Design 1. Material Characteristics Category Measures Physical state Size Weight Shape Condition Safety risk and risk of damage Solid, liquid, or gas Volume; length, width, height Weight per piece, weight per unit volume Long and flat, round, square, etc. Hot, cold, wet, etc. Explosive, flammable, toxic; fragile, etc.
