Elevator Door Triangle Lock OTIS Elevator Triangular hall door lock Parts

The elevator triangular lock is a tool specially used for emergency unlocking of elevator landing doors, also known as a triangular key. It has a triangular hole at one end and is a special tool for emergency unlocking of elevator landing doors.

Elevator triangular locks are professional and must be used by trained or authorized professionals. Even for professionals, written instructions should be provided when using the key, detailing the precautions that must be taken to prevent accidents that may occur due to failure to effectively re-lock after unlocking. 

In addition, the elevator triangular lock is universal, ensuring that it can be used by personnel dealing with public emergency or safety affairs. For example, trained firefighters can carry a key to open the elevator door of any brand. 

The use of elevator triangular locks must strictly follow relevant management regulations. Unauthorized, untrained, and unqualified use of triangular keys can easily lead to accidents. Authorized personnel must ensure that the elevator has stopped running, turn on the lighting at the floor door, remove all debris, place guardrails, and make sure there are no other unrelated people around. 

The operator should stand well, maintain the center of gravity, insert the triangular key into the lock hole, and follow the steps after confirming that it is in place.
