PCT No. PCT/GB84/00391 Sec. 371 Date Jul. 29, 1985 Sec. 102(e) Date Jul. 29, 1985 PCT Filed Nov. 12, 1984 PCT Pub. No. WO85/02427 PCT Pub. Date Jun. 6, 1985.The machine comprises a vibrator (26) for applying vibratory forces, and a member (30) for applying non-vibratory forces to a vibratory tool carrier (52) to which is removably attached a working tool, e.g. a bucket (14). The vibrator includes an eccentric (50) and is driven by a drive (36-38). The tool carrier incorporates a first mounting (at 50) for its connection to the vibrator and a second mounting (34) for its connection to the member. The second mounting enables reciprocation of the tool carrier at the point of its attachment to the second mounting when the vibrator is in operation. The first and second mountings are spaced from each other in the direction of the reciprocation. |
