A railroad machine (1) for continuously laying the power wire (2) and the supporting cable (3) of an overhead line (4) of a track consists of a machine frame (10), which is mounted on rail bogies (8) and can be displaced via a travel drive (9) which can be tailored to the laying speed, storage drums (33,34) for the power wire (2) or the supporting cable (3), a tensile stress device (37,38) which is arranged in front of the storage drums and can be acted on via a drive (45) and a control device - and which is assigned at least one guide roller - and a lifting device (20) which is vertically adjustable via drives and has a swivellable extension arm (17) for vertically and laterally adjusting a supporting and guiding roller (18,19). The tensile stress device (37,38) is composed of two deflection rollers (41,64) which have diameters of the same size, are rotationally connected to one another by a drive (40), are constructed in order to repeatedly wrap the power wire (2) or supporting cable (3), are spaced from one another in the longitudinal direction of the machine and are assigned a hydraulic rotational drive (45). <IMAGE> |
