Shaft-driving plant for sinking shafts or the like in rock, consisting of a framework (18), which carries a working stage (14) from which boring operations and the like are carried out, and of a drive unit (32, 34) which moves the plant on a rail guide (4) which is composed of several individual sections which can be successively connected to one another during the shaft driving and can each be fastened to the shaft wall from the working stage. The framework (18) carries a lifting device (50, 70), by means of which a lifting platform (78) carrying a rotary drill-boom device (110) can be moved with regard to the framework (18) towards and away from the working stage (14). The lifting device (50, 70) has a lifting tower (50) which carries the framework (18) at a distance from the latter and in an extending manner along the same, the lifting platform (78) and a lifting mechanism (70) for it being movable along the lifting tower (50). <IMAGE> |
