[0002] Elevator travelling cable is a kind of power cable specially designed for elevator system. It is used to connect the control system inside the elevator car and the machine room, transmitting signals and power supply.

[0003] One end of the elevator travelling cable is connected to the machine room control cabinet, and the other end is fixed on the elevator car and moves with the elevator car. The elevator travelling cable runs with the elevator, and the travelling cable will swing during the movement of the elevator. In the case of small elevator shaft space, the cable will hit the elevator shaft components and cause abnormal noise.

[0004] However, the existing method is to hang a weight on the elevator travelling cable to prevent the cable from swinging. If the suspended weight is too light, it cannot prevent the cable from swinging, and if the suspended weight is too heavy, it will increase the burden on the elevator travelling cable and the elevator itself. Therefore, it is necessary to develop a weight mechanism that can easily adjust the weight and is suitable for elevator travelling cable. UTILITY MODEL CONTENT
