We have now added Load arrestors to our ever growing product range. If a heavy load goes into free fall you want it to be arrested as quickly as possible to avoid injury or damage. The SOLL Load Arrestor catches the load cable glides in and out of the block smoothly, but if there is a harsh pull on the cable (such as a load falling) the unit will arrest and hold any load up to 1000kg (when used with a pully).
