SSteel spring isolators are a very effective and commonly used. Steel spring isolators are typically 95-98% efficient (reduces the transmitted vibration 95-98%) while a pad type can be 75-88% efficient. Spring isolators also level the genset sub-base in the event the foundation pad is not perfectly level.

Spring steel isolators offer the highest level of vibration isolation, however higher levels of vibration (although not detrimental) may be seen on some areas of the genset when mounted on steel springs, due to the (almost) total isolation from the foundation. The base of most steel spring isolators contains a non-skid pad. The base should be mounted to the foundation pad as shown in Figure 2‐1 or as recommended by the isolator manufacturer.

A common practice is to pour a concrete pad directly on top of the floor slab and to mount the genset on this pad. The purpose of the pad is to facilitate cleaning around the genset and to provide a more level base. When using this method, floor strength must support the pad and the genset. The pad should be at least 6in (150mm) thick and extend beyond the genset in all directions 12in (300mm).

Weight Of The Genset

The dry weight of the entire genset is shown on the Generator Set Specification Sheet. The wet weight includes the fluids (coolant and oil). Figure 2‐2 can be used to design the foundation except in critical situations.
