Abstract: PURPOSE: To effectively utilize a space, and prevent damage of a cable and a hose, etc., by coaxially mounting at least two reels under a frame freely to rotate it around a vertical axis in a vertical direction to each other. CONSTITUTION: An apparatus comprises a cable reel 3 and hose reel 4, and the cable reel 3 and the hose reel 4 are coaxially mounted under a frame 6 of a rock drilling apparatus freely to rotate around a vertical axis 5 and to wrap over in vertical direction to each other. Two rotating devices which consist of gears 13, 21, rotating motors 14, 22, sprocket wheels 15, 23 and chains 16, 24 are provided, and the cable reel 3 and the hose reel 4 independently wind up a cable 8 and a hose 25 with each rotating device. By mounting two reels 3, 4 in a same structure, a space, which is necessary, is reduced, and damage of the hose 25 and the cable 8 is reduced.
