59300010CL Elevator Door Knife V30 For 5400 300P Left Opening Door Vane Assembly Door Lock Device Left Side

Synchronous Door Opening and Closing (Core Function)
Installed on the top of the car door, it precisely hooks onto the landing door rollers/hooks when the elevator levels, forcibly linking the landing door and car door to open and close synchronously; when the car door closes, it simultaneously locks the landing door, preventing accidental opening of the landing door during elevator operation.

Safety Interlock Protection
Maintains mechanical self-locking when not leveling, prohibiting the opening of the car door/landing door; during elevator operation, the door knife locks, eliminating fatal risks such as "door open and elevator moving" and "landing door falling," making it a key trigger component in the elevator safety circuit.
