DescrizioneWittur 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.
Advanced self-monitoring routines and automatic setup with shaft dimensions determination ensure a fast and easy installation and a reliable fail-safe system. Safety electronics also combine additional functions: UCM detection, absolute shaft encoder, door zone switch, shaft end switches. A backup battery is supplied in the electronic interface box to ensure operation also in case of power loss.
