Crane load limiter HF series

Working principle: The deviation of the cable caused by the intervention of the sensor causes a tangential force that is proportional to the force exerted on the traction cable. In the event of an overload, a microswitch integrated in the sensor is pressed and stops. the electric wire rope hoist.
