Abstract
The significant increase in weight of a mobile steel piece, with an essential function in generating the percussions with high impact energy, cannot be approached without radically changing the inner structure of the piece. Keeping the geometric shape of the piece, combined structures, bi or tri-polar , can be created, able of doubling or even tripling its weight, using the technique of ballasting with known super heavy materials.At this moment, in car-building, they stress upon the use of super heavy materials, able of major energetic performances in the main work body, as an alternative to similar pieces, made only of steel.
