Elevator Hook Lock Door Lock Mechanism

The hook lock and door lock are important components of the elevator safety system.They can effectively prevente safety accidents that could occur due to abnormal situations during elevator operation.
Elevator hook lock is a type of safety lock used for elevator doors, typically found in passenger and machine room elevators. The hook lock is characterized by its simple structure, ease of operation, and good safety performance. It operates on the principle of electromechanical interlocking, meaning that when the elevator starts to operate, the hook lock automatically releases. Once the elevator reaches the desired floor, the hook lock automatically secures the door panels and cannot be opened by external forces. The purpose of the hook lock is to protect passengers from being injured by the elevator door due to misoperation or external interference while the elevator is in motion, thereby ensuring the safe operation of the elevator.
Elevator door lock is also a crucial component of the elevator safety system. It is usually installed on the elevator door panels and tracks, and comes in various types such as confidential, magnetic, and mechanical. The door lock is characterized by its complex structure but significant effectiveness. It automatically locks the door panels when the elevator door is closed, ensuring the internal operational safety of the elevator. The door lock automatically releases when the elevator reaches the destination floor, allowing passengers to open the elevator door smoothly. Additionally, the door lock can perform control and monitoring functions. In case of any abnormal situation, it can automatically cut off the elevator’s power supply, ensuring the safety of the passengers.

Since the elevator hook locks and door locks are important components in keeping the elevator safe, it is necessary to carry out timely testing and maintenance of the hook lock door and door lock, and timely replacement of damaged or obsolete parts to ensure the safe operation of the elevator.
