With a company history of over 100 years, GERB is dedicated to vibration and seismic control of buildings, tall structures, rail trackbeds and large machinery (e.g. emergency generators etc). GERB Tuned Mass Dampers (TMDs) in particular are used worldwide for the vibration control of pedestrian and wind induced vibration of long-span and slender structures (e.g. floors, bridges, skyscrapers, etc.). GERB systems are based on well established physical principals using elastic elements and the VISCODAMPER, a viscous fluid dashpot/damper that is frictionless and can work at very low amplitudes.
