ABSTRACT:
A forging hammer is isolated from a foundation by a shock and vibration control system composed of an inertia block and a multiplicity of shock-vibration isolators that are installed on pedestals spaced a dimension X below the bottom of the inertia block that is substantially equal to the sum of the loaded height H of an isolator and the height S of one or more permanent load-supporting spacers installed between the top of each isolator and the bottom of the inertia block. The height S of each spacer is greater than the sum of (1) the difference between the unloaded height and the loaded height of the isolator and (2) the minimum height of a jack suitable for loading the isolator in place so that the isolator can be inserted in position on the pedestal under the inertia block in unloaded condition and loaded using the jack and the spacer (or spacers) installed while the inertia block and forging hammer are temporarily supported on piers which include removable spacers that are taken out after the isolators are installed.
