Hitachi elevator door locks are key safety components installed on elevator car doors and floor doors (or hall doors). They are not only a prerequisite for the normal operation of the elevator, but also an important line of defense to ensure passenger safety. The working principle of the door lock device is mainly based on two mechanisms: mechanical locking and electrical verification. When the elevator door is closed, the lock hook and the lock stop engage to lock the door panel in the closed position, and the electrical contacts are connected at the same time.
