GRL Designs have been manufacturing LIMITLOAD crane overloads for more than 30 years providing a very reliable low-cost solutions to overload protection.

The original LS design is electo-mechanical using a Micro Switch to detect overload or slack rope conditions.

An updated LSW version is fitted with 2 synchronised switches  providing additional safety and satisfying the requirements of BS EN12077-2 & BS EN13849-2.

These units simply bolt onto a static wire rope and detect the load. Units are available up to 100kN (10,200kg) load on the rope and rope diameters up to 24mm.
