Summary
Pallet lifters are machines for moving pallets. This document describes the design and standardisation of pallets and pallet lifters. Students get information about pallet sizes, benefits of standardisation, and design considerations for pallet lifters.
Pallet Standardization
A 1000mm x 1200mm 4-way entry pallet is recommended. This size is compatible with standard containers and trucks. It is widely used in Asia and endorsed by ECR Asia. It conforms to international and Singapore standards.
Benefits of Pallet Standardization
Standardisation of pallets allows for pallet exchange. This improves productivity and work efficiency. It reduces labour, handling costs, and damage to goods. It also facilitates automation and regional trade.
Pallet Lifter Design
Designing a pallet lifter involves considering the strength of materials, safety factors, and stress limits. The document specifies beam dimensions, weights, and allowable stresses for the pallet lifter design. It also discusses failure modes and allowable forces for different parts.
Materials for Pallet Lifter
The document lists materials used in the pallet lifter design. These include ASTM A500 mild carbon steel and ASTM A36 steel alloy. It provides details on the dimensions and quantities of these materials for different parts of the pallet lifter.
Key terms
- 4-way entry pallet
- A pallet that can be accessed from all four sides for lifting.
- ISO 6780
- An international standard for general-purpose flat pallets.
- Strength of materials
- The ability of a material to withstand applied stress without failure.
- Factor of safety
- A design factor used to account for uncertainties in material properties and loading conditions.
- Allowable tensile stress
- The maximum tensile stress that a material can withstand without failing.
- Allowable shear stress
- The maximum shear stress that a material can withstand without failing.
