During the handling of loads, hoists are often used that lift defined weights and require the operator only to move them horizontally. This means however that the vertical movement must be controlled by the operator by means of actuators. If this operation is too difficult or complicated, the operators' acceptance of the hoists drops, and in extreme cases they may even revert to handling loads entirely manually.
A simple and intuitive control system is one that detects the operator's movement directly rather than via additional control elements, and does not require control commands to be entered.
No relevant ergonomics standards for balancers 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.
