Zusammenfassung:The utility model relates to an automatic powerdown levelling door opener for an elevator, which is mainly composed of a speed sensor (1), connection interfaces (2), an SCM control system (3), a clutch (4), a stopper (5), a small motor (6), a door-opening motor (7), a levelling sensor (8) and a power supply (9), wherein, the SCM control system (3) judges and automatically determine the direction of light load according to the rotation speed of the speed sensor (1), and receives the levelling signal and the end signal that are emitted by the levelling sensor (8), so that the purposes of automatic levelling and door-opening when the power of the elevator fails is achieved. The utility model has the characteristics of simple structure, low cost, high safety, etc.
