Tugger trains are often used to transport material to production centres in series production installations. They consist of a tractor and a number of trucks, the design of which differs according to their function and load.
Simple shelf trucks may be used where the materials are diverse or quantities low. However, these trucks can be loaded only from the side, which may present problems. This gives rise to high-stress work situations, particularly where materials are heavy.
No machinery standards relevant to tugger-train trailers are known.
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.
