1. How does the elevator work?

      The elevator has a car and a counterweight, which are connected by wire ropes. The wire ropes are driven by the traction of the drive device (traction machine) so that the elevator car and the counterweight move up and down on the inner guide rails of the elevator.

2. Will the rope of the elevator break?

      For elevators used for wire rope elevators, the country has special regulations and requirements. The configuration of the wire rope is not only to bear the elevator car and the rated load, but also to consider the size of the traction force. Therefore, the tensile strength of the steel wire rope is greatly greater than the load capacity of the elevator, and their safety factors are all above 12. The general elevators are With more than four wire ropes, one elevator wire rope will not break.

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

      If an unexpected power outage or failure of the power supply line occurs during the operation of the elevator, the elevator will automatically stop running and there will be no danger. Because the elevator itself is equipped with electrical and mechanical safety devices, once the power is cut off, the actuator of the electric body will automatically brake so that the elevator cannot run. In addition, if there is a planned power outage by the power supply department, the elevator or the elevator will be stopped in advance if it is notified in advance.

4. What to do if the elevator runs suddenly?

      The running speed of the elevator, whether up or down, shall be operated within the specified rated speed range. Generally, it will not be over-speed. If there is over speed, there is an anti-overspeed device in the elevator control system. At this time, the device will automatically operate. Decelerate or stop the elevator.

5. Does the elevator car overload automatically control?

      The load capacity of the elevator varies according to the requirements. The elevator can only be operated within the specified load. If the elevator exceeds the limit, the elevator will automatically alarm and cannot operate.

6. When the elevator is closed, will it cause harm to people?

      In the process of closing the elevator, if the hall car door meets people or objects, the door will automatically restart and will not hurt anyone. Because the door is provided with a switch for the protection of the family, once the door touches people or things, this switch action prevents the elevator from closing and reopening, and then closes the door again. In addition, the closing force is set by the degree that will not be achieved.

7. Can elevator doors be opened?

      The hall door of the elevator cannot be opened outside the court, and must be opened with special tools (installed by the maintenance staff). When passengers are not allowed to knock on the door, they cannot open it, otherwise there is a danger of falling into the well.
