Abstract
A tamping machine designed especially for tamping switch sections comprises two inner and two outer tamping units (13, 24). Each outer tamping unit (24) is designed to be pivotable about a pivot axis (26), extending in the longitudinal direction of the machine, relative to a guide block (25) connected for displacement to transverse guides (12) and to a transverse displacement drive (14), and is connected to a pivot drive (27). Thus, tamping tools (18) of the outer tamping unit (24) can be positioned at a maximum distance from a machine center (23) for extensive tamping of a branch rail.
Claims4
A tamping machine having two inner tamping units (13) adjacent to one another—with respect to the transverse direction of the track or machine—and two outer tamping units (24) adjoining the former in each case, wherein the tamping units (13, 24) are transversely displaceable independently of one another on transverse guides (12) by means of transverse displacement drives (14) and are equipped with tamping tools (18) which are supported on a tool carrier (17) vertically adjustably connected to an assembly frame (15) via guides (16), wherein each outer tamping unit (24) is designed to be pivotable about a pivot axis (26), extending in the longitudinal direction of the machine, relative to a guide block (25) connected for displacement to the transverse guides (12) and to the respective transverse displacement drive (14), and is connected to a pivot drive (27).
