Hird’s Secondary Safety Device offers an additional safety factor when using Hird’s range of vacuum lifters. Designed to be securely tightened around the load and attached to the crane hook using heavy duty polypropylene straps. In the event of a machine failure resulting in the loss of vacuum, Hird’s secondary safety device will allow the load to be safety lowered to the ground. Variable length side straps allow use on most types of lifters.
