ABSTRACT:
A mobile ballast tamping machine comprises a tamping unit associated with, and adjacent, the field side and the gage side of each track rail, the field side and gage side tamping units associated with each rail being adjacent each other in a direction extending transversely to the track and each tamping unit comprising a pair of vibratory tamping tools reciprocable in a direction extending substantially parallel to the track, a vertically adjustable tamping tool carrier supporting the pair of tamping tools, a support frame, vertical guides connected to the support frame and vertically adjustably supporting the tamping tool carrier, the support frame of each field side tamping unit being supported on the support frame of the adjacent gage side tamping unit. A displacement drive is connected to each field side tamping unit support frame for adjustably spacing the field side tamping unit support frame from the adjacent gage side tamping unit in the transverse direction, and a guide extends in the transverse direction and supports the gage side tamping units for independent displacement in the transverse direction.
