The elevator in the community is broken and the property is not repaired. What department should I complain to?

You can contact several owners and complain to the Municipal Quality Supervision Bureau or the Safety Supervision Bureau. If there are major security risks, the law enforcement officers of the two departments will issue a written rectification instruction to the community management Committee, and order the residential property and elevator production enterprises to complete it within the specified time.

Elevator failures are mainly manifested in the following aspects:

1. Failure of electrical safety device;

2. Insufficient braking torque;

3. Insufficient traction;

4. The speed limiter fails;

5. The safety clamp is broken.

Extended data:

The elevator has a car and a counterweight, which are connected by wire rope. The steel wire rope is driven by the traction of the driving device (traction machine), which makes the elevator car and counterweight move up and down on the guide rail in the elevator.

The guide shoes fixed on the car can move up and down along the fixed guide rail installed on the wall of the building shaft to prevent the car from tilting or swinging during operation. When the motor is working, the normally closed block brake releases the brake to make the elevator run, and when the power is cut off, the brake stops the lift of the car and keeps it in a static state at the designated landing for people and goods to enter and exit. The car is a box-shaped component that carries passengers or other loads. The counterweight is used to balance the car load and reduce the motor power. The compensation device is used to compensate the tension and weight changes in the movement of the traction rope, so that the load of the traction motor is stable and the car stops accurately. The electrical system realizes the control of elevator movement, and at the same time completes the work of floor selection, floor leveling, speed measurement and lighting. Instruct the call system to display the running direction and floor position of the car at any time. The safety device ensures the safe operation of the elevator.

Safety monitoring

1, computer room environment

2. Control room

3. Main power switch

4. Moving wheel

5. Speed limiter

6. Shaft and pit

7. Guide rail

8. Landing doors and cars

9. The counterweight should have reliable fixture to prevent loosening.

10, speed limiter tensioner and steel belt tensioner shall be equipped with safety switches.

1 1. When the elevator is running, the compensation chain and rope shall not collide with the shaft or other parts.
