SYNCHRONOUS VIBRATORY IMPACT HAMMER

摘要

A vibratory impact hammer (1) including a hammer body assemblage (9) suspended by rubber mounts (11) for reciprocal axial movement in a support frame (3), the rubber mounts providing guiding and damping action of the assemblage in either direction of axial movement without extraneous friction forces acting thereupon, and a pair of synchronously driven eccentric weights (19,21) which are arranged to provide vibratory movement of the assemblage.
