The anti-trap protection on the ergonomic handle with rotary joysticks is implemented with a pressure-sensitive mushroom button. If the button is pressed against the operator, the trolley will go back a little in the opposite direction. In case of the ergonomic handle with power sensor, the power sensor has the function of an anti-trap protection. The handle is capable of detecting very small levels of force (max. 28 N required at 1,000 kg).
