The KONE KM902670G15 is a type of door knife model of KONE Elevator, which is commonly used in various types of elevators such as passenger elevators and freight elevators. Here is some information about it:

• Basic parameters: It is applicable to various types of elevators, including passenger elevators, freight elevators, medical elevators, vehicle elevators, and construction elevators. Its rated load is 1000 kilograms, the rated speed is 1.75 meters per second, the operation control mode is collective selection control, and the driving mode is traction.
• Structural features: It adopts a mechanical locking hook structure and closely cooperates with the elevator door lock and door machine system. The blade of the door knife is usually made of high - strength wear - resistant material, which can withstand frequent door opening and closing actions and a certain impact force, ensuring that it is not easy to deform and damage during long - term use.
• Working principle: When the elevator control system sends an opening signal, the door machine system drives the door knife to move. The blade of the door knife is inserted into the locking hook of the landing door lock. Through the action of the door knife, the locking hook is driven to open, thereby realizing the synchronous opening of the landing door and the car door. During the closing process, the door knife first drives the locking hook of the landing door lock to reset, and then the car door is closed to complete a door opening and closing cycle.
• Maintenance and repair: Regularly check whether there is wear, deformation, or cracks on the blade of the door knife, and replace it in a timely manner if necessary. At the same time, ensure that the matching clearance between the door knife and the door lock hook meets the requirements, which is generally 2 - 3 millimeters. Also, check whether the installation bolts of the door knife are loose, and whether there is any jamming phenomenon during the movement of the door knife. If so, adjust and repair it in a timely manner.
