Abstract (en)
[origin: EP0255564A1] 1. A travelling machine for the continuous replacement or renewal of a laid track consisting of rails and sleepers comprising an elongate, bridge-like machine frame which is monted at either end on on-track undercarriages and which consists of two frame section spreadable against one another by vertically and horizontally acting, hydraulic pivoting and locking drives and interconnected by a frame coupling in the region of an intermediate on-track undercarriage vertically displaceable by the spreading effect the two undercarriages for lifting and spreading the old rails, for taking up the old sleepers, for grading the trackless part of the ballast bed, for laying the new sleepers on the graded bed and for spreading and laying the new rails on the new sleepers, characterized in that the ballast grading unit is formed by an endless ballast clearing and grading chain (31) which is designed to grade and, at the same time, trim only that layer or surface (30) of ballast remains after lifting to the rails (3) and in that a ballast conveyor system (42) associated at its receiving end (46) with the ballast clearing and grading chain (31) is arranged on the rear frame section (14) - in the working direction - of the bridge-like machine frame (10) equipped with the rear on-track undercarriage (9), the ballast conveyor system (42) being associated at its discharge end with a ballast distributing unit (43, 56, 67) designed for the measured introduction of the ballast taken up at the ends of the newly laid sleepers behind the rear on-track undercarriage of the rear frame section (14).
