Product principle：

The elevator door machine is a mechanism responsible for opening and closing the door of the elevator hall. When it is opened and closed by the elevator, the elevator door machine controls the door motor through its own control system, turning the torque generated by the motor into a specific direction of the force, closing or opening the door. When the door closing force is greater than 150N, the gantry crane automatically stops and closes the door and opens the door to a certain extent.
