What is known as the "silent killer" in traction elevator pits?

The term "silent killer" in traction elevator pits refers to the counterweight. In the context of traction elevators, the counterweight is used to balance the weight of the elevator car, which improves the efficiency of the elevator system. However, it can also represent a hazard if not properly managed.

The reason this is considered a "silent killer" is due to the potential for severe injury if someone is struck by a moving counterweight, which often operates at high speed and is sometimes difficult to see. In addition, the counterweight's natural motion and weight mean it can create significant momentum, making it particularly dangerous in an uncontrolled situation. The risks associated with counterweights emphasize the importance of safety protocols and awareness when working in areas where they are present.

By recognizing the hazards associated with counterweights, workers can take necessary precautions to safeguard themselves in potentially dangerous environments, making proper training and adherence to safety practices crucial.
