LF-Four Panels Centre Opening Car Door

Short Description:

The elevator door operator is the opening and closing device of the elevator car door. The door opening motor is controlled by its own control system, and the torque generated by the motor is converted into a force in a specific direction to close or open the door. When the closing force is greater than 150N, the door operator automatically stops closing the door and opens the door in the opposite direction, which has a certain degree of door closing protection.

At present, door drive is with VVVF type or PM type mostly.
