ARD is the abbreviation of elevator power automatic rescue device. It’s working principle is to be in the operation of the elevator suddenly meet power system fault (power, phase, lack fire). Cause of elevator control system can not run normally, thus when passengers are trapped. This device will automatically work. In a certain time to provide the required power, and will lift operation flat position, open the car door for passenger safety walked out of the elevator.
ARD is easy to install, convenient debug, high cost performance, safety and general is well praised by the users from all walks of life. At present, ARD is applied to the elevator in domestic and international famous brands. As an important part of the elevator configuration.
