Elevator door lock plate elevator plate accessories bracket

Installation location and size requirements
● Precise positioning: The plate should be installed on the edge of the elevator car door, at the same level and in the same position as the hall door lock device, to ensure that when the car door is opened and closed, the plate can accurately trigger the unlocking and auxiliary closing of the hall door lock.
● Size matching: Its length, width and other dimensions must match the matching dimensions of the car door and the hall door lock to ensure normal triggering and transmission functions. The general length is about 20-30 cm and the width is about 3-5 cm.

Installation horizontal and vertical requirements
● Horizontal degree: After installation, the plate must be kept horizontal, and the horizontal deviation should not exceed 0.5/1000. A level ruler can be used for measurement and adjustment to ensure the stability of the plate in the horizontal direction to avoid poor coordination with the hall door lock due to tilt.
● Verticality: The verticality deviation of the plate should not exceed 1/1000. Use plumb line and other tools to check and adjust to ensure that the relative position of the plate to the car door and hall door in the vertical direction is accurate to prevent deflection and affect the normal triggering of the door lock.

Connection and fixing requirements
● Firm and reliable: The plate should be firmly connected to the movement system of the car door, and the connecting screws should be tightened to prevent the plate from loosening, displacement or falling off during the movement of the car door. Usually, the tightening torque of the screws should meet the requirements of relevant standards.
● Connection method: Generally, screw connection or welding is used for fixing. The welding quality must be ensured during welding. The weld should be uniform and firm, without defects such as false welding and leaking welding; when screw connection is used, the screw specifications should match the connection between the plate and the car door, and anti-loosening washers should be installed.
