Abstract: A vertical drilling boom for a rock drilling equipment includes a vertical boom (2) mounted at its lower end turnably about a horizontal shaft (6) with respect to a carrier (1) of the rock drilling equipment. The vertical boom (2) comprises two boom portions (2a, 2b) mounted longitudinally slideably with respect to each other and an actuating device (2c) for displacing the boom portions (2a, 2b) with respect to each other to adjust the length of the boom (2). An actuating device (7a, 7b) for turning the boom (2) about the shaft (6) and a boom head (3) for turning a feeding beam (12) of a rock drilling machine mounted to the boom (2) about a shaft (5) transverse, preferably perpendicular, to the longitudinal axis of the boom (2) are provided. Motors (5a, 5b) are provided for turning the boom head (3).

Abstract: An apparatus for storing drill rods, comprising two drill rod cartridges each comprising a rotating rotor provided with finger boards, guides for guiding the drill rods into gaps formed by the finger boards circumferentially around the axis of the rotor. The rotors are arranged to rotate in opposite directions in such a way that projections in the finger boards of one rotor are positioned in alignment with gaps in the other rotor, the drill rods being positioned therebetween and then passed alternately with the rotor of the two cartridges along spirals to a circumference about the rotors.
