RK-71 Revision Box
In case of mains failure, it moves the lift which stopped between two floors to floor level, opens the automatic door, and passengers are evacuated in safety. For lifts with automatic doors, if mains failure occurs at floor level, the door is opened and passengers are evacuated. Works open loop. No need to put a sensor on the motor. RK-71 gets the power from a 5 x 12V/7Ah battery set which needs no maintenance. Thanks to the smart battery charge system which does not tire the batteries and makes them work for many years. The starting delay of rescue operation can be adjusted for buildings that have diesel generators. Leveling is done in the easiest way (up with the unloaded car, down with the fully-loaded car) Motor driving frequency and motor torque can be adjusted in a menu for easy start-up.
