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.

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 rope is not only to carry the elevator car and rated load, but also to consider the traction. Therefore, the tensile strength of wire rope is much greater than the load of elevator, and their safety factors are all above 12. Usually, elevators are equipped with more than four wire ropes. Generally, elevator wire ropes will not break at the same time. The elevator has a high safety factor. If the wire rope is found to be broken, the elevator will stop using 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 operate. In addition, if there is a planned power outage, the power supply department will notify in advance and the elevator may stop running in advance. When the elevator is powered off, there is a safety clamp at the lower part of the car, which will jam the guide rail and fix the car on the guide rail without slipping down. In some elevator controllers, there is an emergency power supply. When there is a sudden power failure, the power in the emergency power supply is enough to send the car to the nearest floor and open the door for passengers to escape safely.

4. What if the elevator suddenly speeds up?

The running speed of the elevator, whether ascending or descending, should be within the specified rated speed range, and generally will not exceed the speed limit. In case of overspeed, there is an anti-overspeed device in the elevator control system (the speed limiter will act when the elevator speed exceeds 1 15% of the rated speed). At this time, the device will automatically act to slow down or stop the elevator.

5. Can the overload of elevator car be automatically controlled?

The load capacity of the elevator varies according to the needs. The elevator can only run within the specified load. When the load is exceeded, the elevator will automatically give an alarm and cannot run. There is a special weighing device at the top of the carriage, and the load can be adjusted.

6. Will it hurt people to be caught when the elevator is closed?

In the process of elevator closing, if the car door touches people or things, the door will automatically reopen without hurting people. Because there is an anti-pinch switch on the door, once the door touches people or things, this switch action will make it impossible for the elevator to close the door, and then open the door again. In addition, the closing force is stipulated and will not reach the level of hurting people. If the door is closed to the end, it won't open again. Please pay attention.

9. Are there any protective measures for the bottom squat of the elevator?

The elevator squats on the bottom floor, that is, when the control system of the elevator completely fails, the elevator car will run down beyond the first floor position until it stops squatting on the buffer in the pit. Buffers are protective devices for this purpose. According to the different running speed of the elevator, this protection device can be divided into two types: spring type and hydraulic type. A car lying on the bumper is called squatting. At this time, the buffer can reduce the impact of the elevator car, so as not to cause serious harm to the passengers in the elevator.

10. What should I pay attention to when the elevator suddenly loses power or breaks down and is trapped in the car?
