Current elevator systems employ mechanical and electrical safety devices for handling the hazards of falling and toppling, the primary safety devices having speed limiters, safety tongs, bumpers. The speed limiter is the safety protection device of the elevator. The speed of the elevator car is monitored and controlled at any time, and when the overspeed condition occurs, namely 115% of the rated speed of the elevator, a signal can be sent out in time, and then a mechanical action is generated to cut off a power supply circuit, so that the traction machine is braked. The car is forced to stop by the action of safety tongs mounted at the bottom of the car if the elevator is still not braked. The speed limiter is the command issuer and the safety gear is the actuator. The combined action of the two gives rise to the theory of a safety elevator. The buffer is mounted in the pit of the elevator hoistway. Its function is to prevent the elevator pier bottom.
