One Way Lift Governor Rope for Gearless Traction Machine (SN-SG-XS240)
The One Way Lift Governor is a critical electromechanical safety device designed to prevent elevator over-speed conditions in a single direction (typically downward movement). As a specialized variation of traditional governors, it provides targeted protection while allowing normal bidirectional operation until a safety threshold is exceeded.
Operating Principle:
Engages only when downward speed exceeds 115-125% of rated speed
Triggers via centrifugal flyweight mechanism or electronic sensors
Activates safety gear system to halt elevator car progression
Technical Features:
Directional Sensing: Distinguishes between normal ascent and dangerous descent
Tripping Mechanism: Mechanical (spring-loaded) or electromechanical activation
Speed Calibration: Precisely adjustable for different elevator classifications
Compact Design: Reduced footprint for machine-room-less installations
This governor is for machine room,with the anti-slip function when door opens on leveing, to stop moving down of cabin, improve the safety of lift.
| Rated speed: | V=0.25~2.5 m/s |
| Rope wheel diameter: | Ф240 mm |
| Speed limit wire rope: | Ф6mm |
What is an overspeed governor?
An overspeed governor is an elevator device which acts as a stopping mechanism in case the elevator runs beyond its rated speed. This device must be installed in traction elevators and roped hydraulic elevators.
