GERB Vibration control Systems

GERB Vibration Control System, Inc., was founded in Chicago in 1988. Since 2000, GERB USA is located in Lisle, a western suburb of Chicago.

For more than 20 years, GERB USA has worked successfully with machine manufacturers, Engineers and Architects to provide innovative solutions to vibration and settlement problems.

GERB USA, a subsidiary of GERB Schwingungsisolierungen GmbH & Co. KG, Berlin, Germany serves the North American market, with customers in the US, Canada and Mexico. We design and supply vibration control systems based on helical steel springs and viscous fluid dampers, specifically for the Metalforming, Forging, Electric Power Industry, and for the vibration and/or seismic protection of buildings, structures and rail track beds. We also design and supply Tuned Mass Dampers (TMDs) for the vibration control of long span or slender structures (i.e. bridges, skyscrapers etc).

Other spring supported applications include support of measurement and test equipment, centrifuges and fans, as well as viscous fluid dampers for piping in power plants and other industrial applications.

GERB USA offers the following services:

• Consultation, concept design, and preparation of machine foundation drawings, including static and dynamic calculations.
• Design and supply of spring elements and VISCODAMPERS® to elastically support machines, equipment and structures.
• Installation supervision.
