Safety Gear
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 Safety Gear
The bi-directional progressive type safety gear BSG-25P is effective in up direction as well as in down direction. 

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.
