The elevator is an indispensable vertical transportation tool in the high-rise building. It is a large and comprehensive equipment for the integration of mechatronics. In order to ensure the safety and reliability of the elevator, the elevator has set up some preventive measures, such as electrical safety device and mechanical safety device. Electrical safety devices include: power control and protection device, power supply phase sequence protection device, door lock electric interlock device, emergency stop switch, overspeed protection switch, overload protection switch, limit switch, emergency stop switch, safety window switch and so on. The mechanical safety device has brakes, speed limiter, safety clamp, buffer, door hook lock, door safety touch plate and so on. These safety devices can ensure the safe operation of the elevator.

1. How does the elevator run?
The elevator has a car and a pair of weights. It is connected by wire rope. The wire rope is driven by the driving device (traction machine) to make the elevator car and the elevator move up and down on the guide rail of the elevator.

2. Is the wire rope broken in the elevator?
The elevator for the steel rope elevator special, the state has special regulations and requirements. The wire rope configuration not only for take the elevator car and rated load, considering the size of the traction force, therefore, the tensile strength of steel wire rope is much larger than the load of the elevator, the safety coefficient of them are more than 12, more than four are equipped with general elevator wire rope.

3. Is there a danger of sudden blackouts in the elevator operation?
In the operation of the elevator, if there is a sudden outage or failure of the power supply line, the elevator will stop running automatically, and there will be no danger. Because the elevator itself has electrical and mechanical safety devices, once the power outages, the elevator brake will automatically brake, so that the elevator can not run. In addition, the power supply department, if there is a planned outage, will be notified in advance, elevator or stop operation in advance.

4, how do the elevator run suddenly?
The running speed of the elevator either upward or downward, shall be run at rated speed within the prescribed scope is generally not speeding, if speeding in the elevator control system is overspeed prevention device, at the same time, the device will automatically start the elevator, slow down or stop operation.

5. Can the overloading of the elevator car be controlled automatically?
The weight of the elevator is different according to the needs. The elevator can only run within the specified load. When the elevator is over, the elevator will automatically alarm and can not run.

6, when the elevator closes, will the clip be hurt to the man?
In the course of closing the door, if the door meets people or things, the door will automatically reopen, and it will not hurt. Because there is a switchgear switch on the door, once the door touches people or objects, the switch can not close the door and reopen the door, then re close it. In addition, the closing force is stipulated.

7. Can the elevator door open?
The hall door of the elevator can not be opened outside the car. It must be opened with a special tool (the tool is mastered by the maintenance personnel). Passengers are not allowed to pick up the door, and can not be opened, otherwise there will be a risk of falling down the bottom of the well.

8. How do you call the elevator?
When you need to take the elevator, you should choose the direction button that you want to go on the floor panel of the elevator hall. Press the upper direction button up and down the direction button down. The elevator adopts the way of parked in the control system, if the elevator is in the opposite direction to this layer and does not stop.

9. Are there any protective measures for the bottom and the top of the elevator?
The elevator squats bottom is the elevator car, when the control system is all failed, it will go beyond the first level level position and go down until it crouches to the buffer on the bottom pit. The buffer is the protective device set for this purpose. According to the different speed of the elevator, the protective device is composed of two kinds of spring type and hydraulic type. When the car is squatted on the buffer, it is called a squatting bottom. At this time, the buffer has a relief effect on the impact force of the elevator car, and it does not cause serious damage to the passengers in the elevator.

10. When the elevator is not running normally, how do you do it in the car?
When the elevator, the elevator has found speeding or slower, according to manipulate disk on the red emergency stop button, the elevator will automatically stop, and promptly notify the elevator maintenance personnel.

11, find the elevator car smell in the car, how to do it?
When the elevator car is abnormal smell, should be to manipulate disk on the red emergency stop button, the elevator car, and promptly notify the elevator maintenance personnel.

12, find the elevator has abnormal vibration, when the scraping phenomenon, how to do?
When you take the elevator, the elevator found abnormal vibration, jitter, scratch, manipulate disk should press the red emergency stop button, the elevator car, and promptly notify the elevator maintenance personnel.

13. When the elevator is suddenly blackout or malfunction, what should be noticed in the car?
When you are locked up in the car, you should obey the conductor of the elevator driver. If there is no driver, you can contact the relevant personnel through the communication device in order to save it. Do not force the door or jump out of the door, so as not to be dangerous.

14. What should be paid attention to when entering the car?
When you enter the car, if the elevator door is open, we need to see whether the elevator is in the level position or whether the car is on the floor. Especially at night, when the light is not clear, we should pay more attention to it, otherwise it may cause injury, and we should hurry up and go out quickly.

15. Should the elevator installation and repair units and the maintenance and operation personnel be qualified?
Yes. The elevator installation, maintenance and transformation unit should get the qualification certificate issued by the quality and technical supervision department before it can engage in the corresponding work. The elevator installation, maintenance and elevator operators should get the special personnel operation license and hold the certificate.

16. What is the emergency of the elevator to call 110?
When there is an emergency in the elevator, there are people who are hurting, trapped (trapped in the elevator car, unable to find elevator maintenance personnel). You can call the 110 alarm phone.

17. What is the case where the elevator can make a complaint of quality or safety?
When the elevator often closed, clamping, rough layer, top, bottom, squat lift driver or maintenance personnel without a license, the driver often off-site, car inspection certificate or the certificate has expired, the abnormal noise or sound lift, abnormal vibration or jitter, the car abnormal smell lift, speed too fast or too slow, maintenance is not timely, the elevator car without communication or alarm device, can carry out quality or safety complaints.

18. What should be said about the elevator alarm or complaint?
It should be clear about the specific conditions of elevator, and it should be clear about the specific location of elevator, the property right unit of elevator, the contact person and telephone of responsible department, the maintenance and maintenance unit of elevator, and the telephone number.
