Area of application:
This load limiter is specially designed to manage one or two safety thresholds on small and medium capacity overhead travelling cranes.

Operating principle
Deflection of the wire rope exerted by the load limiter produces a tangential force which is proportional to the force exerted on the wire rope when pulled. Deformation of the load limiter body causes the micro witches integrated in the load limiter to open.
