The governor operates based on centrifugal force. Key components include:
Governor Rope & Sheave - Connected to the elevator car, it rotates as the car moves.
Flyweights - Centrifugal force causes them to expand when speed increases.
Triggering Mechanism - If speed exceeds the preset limit, the flyweights engage a latch or switch.
Safety Gear Activation - This triggers the car's safety brakes or stops the drive system.
Mechanical Governors - Traditional, using centrifugal force for activation.
Electronic Governors - Use sensors and control systems for more precise speed monitoring.
Combined Systems - Integrate mechanical and electronic components for enhanced reliability.
Prevents Free-Fall & Over-Speeding - Ensures the elevator stops safely in case of failure.
Compliance with Safety Standards - Meets international regulations (EN 81, ASME A17.1).
Durable & Low Maintenance - Designed for long-term reliability.
Compatible with Various Elevator Types - Suitable for traction, hydraulic, and machine-room-less elevators.
