The LSD12 lift safety gear release device rapidly brakes the elevator by linking the safety clamps on both sides and works in conjunction with other safety devices, such as the speed governor, to form a comprehensive safety protection network. If the elevator overspeeds or malfunctions, this mechanism immediately triggers the safety clamps to lock the elevator, preventing further operation and effectively preventing potential accidents while improving overall system reliability.
