Abstract

A device ( 1 ) for supporting an equipment ( 2 ), especially an upstanding electrical equipment from vibrations is disclosed. The device comprises a base plate ( 3 ), a set of support adapters ( 7 ), a set of viscous dampers ( 5 ) connecting the base plate to the support adapters and a set of wire rope dampers ( 6 ), wherein the set of wire rope dampers bear the base plate and connect the base plate to the support adapters. Further, the set of support adapters connect the viscous dampers and the wire rope dampers to a foundation plate by bolts or alternatively to a shake table via shake table adapters. A set of angular fixtures connect the support adapters to the base plate by means of the viscous dampers. In a preferred embodiment of the device the base plate is orthogonally shaped.

First claim

The invention claimed is:

1. A device for supporting and damping equipment, the device comprising:
