Abstract

A device can actuate and reset a safety gear in an elevator system. The device contains a pressure accumulator, possibly a compression spring, which, in case of need, can move at least two engagement elements of the safety gear essentially synchronously into an engaged position, and a remotely actuatable resetting device, which can retension the pressure accumulator into a ready position.
