[0033] Specifically, when a maintenance worker is repairing and troubleshooting at the bottom of the elevator shaft, the elevator car is located above the maintenance worker. In this case, the device is installed at the bottom of the elevator. When the elevator slides downward, the elevator car can be supported by the extension rod 6 and the extension rod 4 to prevent the elevator from continuing to fall, thereby protecting the safety of the maintenance worker.

[0034] On the other hand, when it is necessary to repair and troubleshoot the top of the elevator car, the elevator car is located below the maintenance personnel. In this case, the maintenance personnel can be suspended from the upper floor of the elevator stop floor to the top of the elevator car through the cooperation of the hanging basket and the equipment.
