crusher foundations. • With spring support, the crusher and its deck are usually supported on just two beams framed into the nearest building column. Only the dead load of the crusher and deck are added to the column load, as dynamic loads are eliminated by the vibration isolation sys-tem. The layout of the structure is thus greatly simplified.
