Emergency-release couplings are self-activated and they disconnect automatically and non-destructively the two coupling halves when a pre-determined calculated break-away force is exceeded.
The emergency-release coupling may be reconnected in an instant and without any repair.
Two different release mechanisms are available in the WALTHER Emergency-Release Couplings programme.
