may result in a different actual live weight figure. Of course, it is wise to over-design the foundation if there is any doubt as to the actual live weight. The amount of live weight is greater in the case of presses having heavy slides and upper dies operated with long stroke lengths and at higher speeds. Figure 2. Plan view of a typical straight-side press bed. The main structure may be of
Traditional machine foundations are bulky and rigid reinforced concrete foundations which provide high-tuned supports for the machine. The total weight of this kind of the foundation is typically 2 or 3 times greater than that of the machine. The massiveness of the foundation affect clearly the design of the structures and equipments of the building where the machine is. The operating
