Abstract
A mount for the safety device in a lift cage comprises an assembly for maintaining a catch system in a readiness position and for the movement thereof in at least one plane during the braking process. A catch housing is supported horizontally fixed in the readiness position and is held in the readiness position by a resilient plate lightly braced against the catch housing. When the safety device is triggered into a braking process the catch housing is urged upwardly against the resilient plate, out of the readiness position wherein the horizontal fixing is cancelled and self-centering of the catch housing in relation to the guide rails can occur. The transmission of braking/catching forces to the cage is damped and progressively sprung through the compression of the resilient plate.
