Presses can be a major generator of impact shock and vibration disturbances in a plant, thereby causing problems with sensitive equipment, offices in the building, or even disturbances with neighbors. The main problem is shock transmission, following the ensuing high frequency vibration caused by the shock.
If a machine generates relatively large forces during its operation, the machine's overall movement on its isolation system tends to become excessive, unless its effective mass is substantially increased. This increase in effective mass can be achieved by attaching the machine rigidly to an inertia block and mounting the inertia block on isolators.
A foundation or mass designed to meet the requirements outlined above may be installed either above the floor level or within a pit below floor level. Isolators employed to support the mass may be made of rubber, steel springs, air springs, or other suitable, resilient material. Required foundation size depends on the reason for its use and on the type and size of equipment.
