The ST chain block is designed for rescue and evacuation works at height and serves for unloading of the connecting and shock-absorbing device during tripping and subsequent lowering of the victim. The technology of using the chain block allows to lift the victim without much effort and to gain a 4-5:1 strength advantage thanks to the ball bearing blocks.
The protective cover of the chain hoist eliminates the possibility of tangling the cords during rescue and evacuation operations.
