What does Hitachi elevator self-service mean?

Hitachi elevator self-help operation means that elevator failure may cause the elevator to stop in uneven area. When troubleshooting or failure is not a major safety failure, the elevator can automatically carry out automatic rescue operation at low speed (15m/min) and stop at the nearest service floor to open the door to prevent passengers from being trapped in the car. This is the' elevator self-rescue leveling function', also known as the' fault low-speed self-rescue operation function'.

There are magnetic switches or photoelectric induction switches on the elevator car, and each floor of the elevator has plane information (magnetic beans). When the position of plane information is consistent with the adjustment of magnetic switch or photoelectric induction switch, it is a plane state.

Extended data:

Elevator is generally driven by traction. The traction machine is used as the driving mechanism, and the steel wire rope is hung on the pulley of the traction machine, with one end hanging the car and the other end hanging the counterweight device. When the traction machine rotates, the traction force generated by the friction between the wire rope and the sheave drives the car to move up and down (E799BE5BA6E4B 893E5B19E31333431366330).

Basic leveling function of elevator:

1, automatic floor leveling function after call-back: the elevator automatically starts running after call-back, and floors are leveled;

2. Power-off automatic leveling function: When the elevator power supply network fails, power is supplied through the power cabinet (ALP) configured by the elevator, and the elevator will run to the nearest service floor at a low speed, and the leveling floor will stop and open the door.
