The cable traction device has a cable (a) clamped between a lower firmly anchored crawler track (c) and an upper movable crawler track (b), carried along with the upper track. The casing parts (h, i) round the cable are hinged to each other and can be moved axially to a certain extent (x). The two hinge bolts (g) at an angle ( alpha ) are connected to each other. |
