The elevator door operator is usually located at the top of a domestic elevator and, depending on the door configuration, the door crane can be located in the middle or side of the front edge of the sedan roof. The elevator door operator drives the deceleration motion with a multi-stage, triangular timing belt, large sprockets, and crank wheels, which rotate by gear clockwise direction, starting with the door and closing behind it. When the door crane chooses to change the speed by changing the internal resistance, it can operate the button switch by the cam installed on the gear transmission shaft, or it can operate the button switch by the bumping bow installed on the window sash to achieve the function of changing the speed. It is a scientific and reasonable choice to use the frequency converter to control the gantry crane, to achieve the stable posture of the automatic door opener, to protect the environment, to save energy, and reduce noise.
