Abstract
A tamping machine designed especially for tamping switch sections comprises two inner and two outer tamping units (). Each outer tamping unit () is designed to be pivotable about a pivot axis (), extending in the longitudinal direction of the machine, relative to a guide block () connected for displacement to transverse guides () and to a transverse displacement drive (), and is connected to a pivot drive (). Thus, tamping tools () of the outer tamping unit () can be positioned at a maximum distance from a machine center () for extensive tamping of a branch rail.
