Objectives of Material Handling Objectives of Material Handling
• Reduce Overhead • Prevent Accidents
–Minimize Non-Productive Labor – Reduce Physical Load Required
–Prevent Damage to Materials – Insure Handling Equipment is Safe

• Conserve Floor Space • Improve Employee Morale
– Avoid Excessive Stock Storage – Provide Proper Relationship Between Employee &
– Move Materials in a Position to Save Space Work
– Use Equipment Requiring No Floor Space


Principles of Material Handling Principles of Material Handling
There are 10 principles of material handling: Planning Principle Standardization Principle

Lifts Chutes


Fixed Path Material Handling Semi Fixed Path Material Handling
• Advantages: Types Advantage & Disadvantages:
– More economical if large volume of material • Cranes • Advantage
moved to same place – Can cover a wider area
– Jib
– One power supply to drive entire “belt” – more – Bridge • Disadvantage
economical – Still limited to area covered
– Gantry
– Reduction in need for lot identification tags
• Tracks
– Can be used to pace the workers
– Monorail
• Disadvantages
– Industrial Rail
– Less economical if material follows diverse paths


Tracks - Monorail
Cranes


Wide Area (Variable Path) Lift truck
Computer Controlled Truck

• Powered • Manual
– Power Lift Truck – Truck (2 Wheel)
– Fork Lift Truck – Truck (4 Wheel)
– Multiple Trailer – Lift Truck
– Yard Truck – Dolly
– Over the road Truck

• Advantage • Disadvantage
– Flexible – Must have portable
power supply with each
piece of equipment

Accessory Items Accessory Items
• Carriers • Hoist Accessories
– Skids – Chains
– Pallets – Clamps
– Slings
