发明名称 APPARATUS FOR DRIVING AN UPWARDLY DIRECTED SHAFT IN ROCK
摘要 The invention relates to an apparatus for driving an upwardly directed shaft (6) in rock, and includes a platform that can be regulated in height. The platform (1) carries a drilling unit (20) having means enabling fixation of the drilling unit (20) relative the wall (7) of the shaft (6). The drilling unit (20) and platform (1) can be separated a given distance such as to form an air gap (60) for preventing the transfer of vibrations from the drilling unit (20) to the platform (1) when a drilling machine (30) pertaining to the drilling unit is in operation. The apparatus has means (40-42) for limiting the separation distance between the drilling unit and platform. The platform (1) carries a work station (54) for a drilling machine operator.
