Cargo elevators are usually equipped with speed limiters. Cargo elevators are usually equipped with multiple safety devices such as speed limiters, safety clamps and buffers to ensure safe operation. These devices can be quickly activated when the elevator is overspeeding, cut off the control circuit and stop the elevator, thereby ensuring the safety of people and goods.
The speed limiter is an important part of the elevator safety system. Its main function is to monitor the running speed of the elevator. When the elevator is overspeeding, the speed limiter will activate the safety device, cut off the control circuit of the elevator, and stop the elevator. The safety clamp will clamp the guide rails to force the elevator car to stop after the speed limiter is activated to prevent the elevator from continuing to fall. The buffer acts as a buffer when the elevator car touches the bottom, reducing the impact force and protecting the elevator structure and passenger safety.
