An elevator lock is a practical equipment that plays an important role in passenger safety, despite its simple function. The existence of an elevator door lock makes sure that the elevator door stays locked when it is running and prevents it from falling into the elevator well or bumping to the walls of it. Therefore, the elevator lock is one of the most significant parts, playing an important role in user safety. In this post, the function, types and cons, and pros of using this part are discussed.

The function of the elevator lock

One of the most important functions of an elevator lock is that it makes sure that the door remains closed. The elevator lock is chosen based on the elevator type of usage. The elevator lock consists of a tab, arm, latch, and two micro switches. These micro switches ensure the closing/opening of the elevator door. One micro switch is captured by the platinum that is mounted on the door, and closes the door, as a result they the electric command circuit of the elevator is created. On the other hand, the other micro switch terminates the connection between the platinum and the lock, once they reach the desired floor, resulting in deactivation of the electricity command circuit and opening of the door. The micro switch responsible for opening the door is considered a lock toggle. In this condition, the bow uses an oil jack under pressure to hit the lock lever to open the door. Then, the passengers can open the floor door and exit the elevator.
