In order to use only one cable-pulling device for drawing in cables with tensile forces of different magnitudes, an outer cable-pulling device suitable for large tensile forces is designed such that it is hollow and contains, inside it, a smaller cable-pulling device for smaller tensile forces, to which the tension cable is attached and is led out through an end opening in the outer cable-pulling device. The latter can be dismantled to gain access to the inner cable-pulling device, which can then be drawn out through this opening, after the removal of conical half-shelves which support the inner cable-pulling device against the end opening in the outer cable-pulling device. <IMAGE> |
