Pramac I-ton pallet truck
When materials are transported by means of manual transport equipment such as pallet trucks or carts, importance is usually attached to the equipment's suitability for universal use. As a result, the design must often be sufficiently robust for larger loads to be transported, which in turn increases the unladen weight of the transport equipment.
In order to reduce the weight to be moved, it may therefore be advantageous for the transport equipment to be engineered for lower weight by the use of alternative materials.

The Technical Report ISO/TR 22100-3 describes how ergonomic principles can be applied during the risk reduction process according to ISO 12100 and how ergonomics standards can be applied to machinery. It helps designers take decisions with respect to ergonomics during the machine design process and can also be used when no relevant type C standards are available.
Equipment such as non-powered trucks or pallet trucks is typically used for the handling of heavy loads. This equipment facilitates transport, but as a result of its construction, which is often solid, its own substantial weight most be moved in addition to that of the load. Depending upon the application, this weight may even exceed that of the load, and may therefore necessitate the exertion of high forces (see also EN 1005-3).
- Stress category
The use of new types of material enabled the weight of the pallet truck presented here to be reduced by up to 50% compared to that of a conventional steel pallet truck. This reduces the forces required for movement, particularly with loads of lower weight.
