Abstract: Disclosed is a phase shifting mechanism which is adapted to shift the phase between the motion transmission members and particularly a phase shifting mechanism suitable for use in vibro hammers.

Abstract: The present invention relates to a gripping machine (1) which is used for driving and extracting applications of steel-formed materials, profiles and steel pipes called as sheet piles, and has at least one gripping unit (2) that enables to position these materials to the floor in a preferred angle during driving.

Abstract: The present invention relates a connection adapter providing the connection of jaws (C) of every kind with vibro hammers (V) of every strength, which are used for driving and extracting of steel formed materials, profiles and steel pipes and further the connection adapter has at least one pressure member (4), which enables that the upper connection piece (2) and the lower connection piece (3) are interlocked by applying a force, if the interlocking of the upper connection piece (2) and the lower connection piece (3) is preferred.

Abstract: The present invention relates to a vibro hammer; which is mounted on parts such as steel formed pipes and profiles and used in driving and extracting these parts to and from the soil, and is able to rotate without resonance; and which, by means of the transmission device whose main parts are the stepped shaft, toothed piston and transmission body, performs phase change between the upper weight set and lower weight set with fewer parts.
