Abstract (en)

[origin: WO2006084980A1] The ramming device (7) comprises a ramming element (9) to be assigned to the end (3) of a rock breaker. The inventive device receives the shocks generated by the rock breaker and transmits them to fragments to be compacted. The ramming device also has a frame (8) comprising: positioning means (15, 16, 17, 18) for positioning relative to the rock-breaker so that the axis (11) of the frame (8) is coincident with the axis (2) of the rock breaker; joining means that enable the temporary and removable fixing of the frame to the end of the rock breaker; axially translational guiding means (10) for guiding the ramming element relative to the frame; means for blocking the rotation of the ramming element about the axis of the frame, and; means (25) for limiting the amplitude of this translation.
