To apply for a residential district, building or unit, the application needs the consent of "more than two-thirds" owners, and the investment ratio of the installation is determined by the owners through voluntary negotiation. It is also necessary to apply to the local street for feasibility demonstration, and finally the conceptual plan and other contents should be publicized.

The main process is as follows

Precautions

1. The elevator is composed of mechanical and electrical parts. If the elevator is not maintained daily, the safety of the elevator will not be guaranteed. If the elevator does not refuel when it needs to refuel, it will cause the wear and damage of the elevator mechanical parts, greatly shortening the service life of the elevator and making it impossible to use the elevator normally.

2. In order to reduce costs and save money, some elevator users look for temporary workers or unqualified companies to do elevator maintenance. Once there is a safety problem, even the responsible company can't be found. If the maintenance is carried out by elevator manufacturers or qualified professional companies, on the one hand, the maintenance technology and quality are guaranteed, and on the other hand, if something goes wrong, someone will be responsible.

frequently asked questions

1. how does the elevator work?

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

the guide shoe 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 lost, it brakes to stop the lift of the car and maintain its static state at the designated landing for people and goods to enter and exit.

The car is a box part that carries passengers or other loads, and 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 can stop 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 calling system to display the moving direction and floor position of the car at any time. The safety device ensures the safe operation of the elevator.

2. Will the steel wire rope of the elevator break?

The steel wire rope for elevator is special for elevator, and the state has special regulations and requirements. The configuration of wire ropes is not only to bear the elevator car and rated load, but also to consider the size of traction. Therefore, the tensile strength of wire ropes is much greater than the load of elevators, and their safety factors are all above 12. Usually, elevators are equipped with more than four wire ropes, and generally, elevator wire ropes will not be broken at the same time.

The safety factor of the elevator is very high. If the wire rope is found to be broken, the elevator will be stopped and put into use after the wire rope is replaced.

3. Is there any danger of sudden power failure during elevator operation?

in case of sudden power failure or power supply line failure during elevator operation, the elevator will automatically stop running without any danger. Because the elevator itself is equipped with electrical and mechanical safety devices, once the power fails, the brakes of the elevator will automatically brake, making the elevator unable to run. In addition, the power supply department will notify in advance if there is a planned power outage, and the elevator may stop running in advance.

when the elevator is out of power, there is a safety clamp at the lower part of the car, which will jam the guide rail, so that the car is fixed on the guide rail and will not slide down. In some elevator controller, there is an emergency power supply. When there is a sudden power failure, there is enough electricity in the emergency power supply to send the car to the floor and open the door to let the passengers get out safely.
