  • Tamping machine
    Patent number: 8448576
    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.

  • Track position correction machine
    Patent number: 8113120
    Abstract: A track position correction machine includes a multi-part machine frame and a satellite frame associated with the machine frame. A first drive displaces the satellite frame relative to the machine frame. A first packing unit and a track lifting unit are disposed on the satellite frame. A stabilization unit is associated with the machine frame. A second packing unit is disposed between the satellite frame and the stabilization unit. A second drive displaces the second packing unit relative to the machine frame.
