Pictures for XIZI OTIS Elevator Door Cam Knife Skate DO3000 Door Locking Device
The door opening and closing action of the door lock is realized by the door operator driving the door and acting on the door lock roller. The closing and locking of the landing door not only depends on the door closing drive of the door operator and the mechanical locking of the door lock, but also depends on the electrical safety device.
