The overspeed governor system is a mechanical unit used to protect against accidental free-fall in rack and pinion lift mechanisms.

The system only operates when the descent speed surpasses a previously established value. The sensors are activated through centrifugal force and wedge the follower pinion against the structure. The wedging is cushioned so the platform is immobilised once it has been braked.
