What are the measures for elevator accidents？

     1. How does the elevator work？

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

     2, whether the elevator wire rope will break？

Hunan ElevatorThe steel wire rope used is specially used by the elevator, and the country has strict regulations and requirements。The configuration of the wire rope is not only to bear the elevator car and rated load，We also take into account the magnitude of the drag force，因此，The tensile strength of the wire rope is greatly greater than the load of the elevator，They all have safety factors above 12，Usually the elevator is equipped with more than four wire ropes，Under normal circumstances, the elevator wire rope will not break 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 deactivated and put into use after the wire rope is replaced。

     3, whether the sudden power failure during the elevator operation is dangerous？

Hunan Elevator CompanyIf there is a sudden power failure or power supply line failure during operation, 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 failure, the elevator brake will automatically brake, so that the elevator can not run。In addition, if the power supply department has a planned power failure, it will be notified in advance, and the elevator will stop running in advance。When the elevator power failure, the lower part of the car has a safety clamp, it will jam the guide rail, the car is fixed on the guide rail, will not slip。Some elevator control cabinet inside the emergency power supply, when the sudden power failure, the emergency power supply inside enough to send the car to the near floor, open the door to let passengers safely out。

     4. What if the elevator suddenly speeds up？

The speed of the elevator is either up or down，All shall operate within the specified rated speed range，You don't normally speed.，In case of overspeed，In the elevator control system is an anti-overspeed device (speed limiter，When the speed of the elevator exceeds 115% of the rated speed，It will move)，此时，The device operates automatically，Slow down or stop the elevator。

     5. Can the elevator car overload be automatically controlled？

The load of the elevator varies according to the need, the elevator can only run within the specified load, beyond the elevator will automatically alarm, and can not run。There is a special weighing device in the top part of the car, and the load weight can be adjusted。

     6, whether the elevator is clamped when it is closed will cause harm to people？

In the process of closing the elevator, if the hall car door encounters people or things, the door will automatically reopen, and will not hurt people。Because there is an anti-pinch switch on the door, once the door touches people or things, this switch action makes the elevator can not close, and re-open, and then re-close。In addition, the closing force is regulated and will not reach the degree of injury。When the door is closed, it will not be opened again, please note。
