Elastic Support of Forging Hammers
Previous forging hammer foundations required large, heavily reinforced concrete foundation to divert the extensive dynamic forces through the foundation into the soil
Previous forging hammer foundations required large, heavily reinforced concrete foundation to divert the extensive dynamic forces through the foundation into the soil. The size of these foundations depended largely on the impact energy and soil conditions. Despite large foundations, vibrations were fully transmitted into the surroundings often causing the hammer to settle and tilt.
GERB developed a system for vibration isolation, which utilizes an inertia block supported by spring elements and Viscodampers. The size of the spring-supported inertia block could be greatly reduced compared to a rigid foundation.

During the seventies, GERB developed the direct spring support of hammers, whereby springs and dampers are installed directly under the hammer. This system can be used under most forging hammers, with the following advantages:

  • Considerable reduction in cost and construction time, owing to the elimination of the foundation block and the considerably smaller foundation pit.
  • Reduction of vibration by at least 80% compared to rigid foundations.
  • Elimination of settling and tilting.
