Electromechanical Safety Gear
WITTUR GLSG-22U is an innovative safety gear, compliant with requirements of EN 81-20/50:2014. Electro-mechanical activation offers very short reaction time and easy synchronization between installed units. Combined with a magnetic strip-based absolute positioning system including safe electronic actuation, it does not require a conventional overspeed governor and its tension weight: fewer components in the shaft and more space for the cabin. 

Wittur ESG is a breakthrough safety system solution for new elevator installations.

Its reliable braking element is combined with the latest SIL3 position and speed detection and electromechanical gear activation:  overspeed  governor, tension device and rope loop are no longer needed, and more shaft space can be used for the car.

Progressive Type Safety Gears
CSGB 01 / 02 / 03 are progressive type safety gears. Braking force is generated through a combination of disc springs and braking elements always in pairs and activated by a movable tripping wedge. The braking force is adjustable by the disc spring assembly.
