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.
Trolleys are often used to transport large material containers, since they enable the container to be moved by hand. In order for the trolleys to be transported to the production line, they are transported directly on the trailers of the tugger train to overcome the need for the container to be handled. However, this may result in high forces having to be exerted when the trolleys are loaded onto the trailers, particularly when high weights and substantial height differences between the trailer and the ground are involved.
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.
