Sala PLA Load Arrestors

The Sala range of Load Arrestors are safety devices used in conjunction with lifting devices, such as cranes and hoists.
The Load arrestor provides independent protection that will arrest the fall of a load in the event of the primary system failing and, being completely independent of the primary lifting system, it reduces the risk of equipment damage and protects personnel in and around the danger zone.
A range of load arrestor available in three body sizes, small, medium, and large to protect loads from 100kg up to 3000kg, with a variety of wire cable lengths.
The load arrestor is installed adjacent to the primary lifting device and fixed to a suitable anchorage point. Its retractable steel cable is then secured to the load. The wire rope is attached to the arrestor via an internal spring loaded drum that keeps the rope under a constant light tension yet allows unrestricted movement of the protected load.
In the event of a failure of the primary lifting device that allows the load to fall or descend too quickly, the arrestor senses a descent speed in excess of 0.5m/sec and automatically engages an internal inertia-activated mechanical brake that acts on the rope drum. This decelerates and stops the lowering of the suspended load within 1m and absorbs the shock forces.
