Abstract:
A telescopic feed beam for a rock drill includes a lower beam and an upper beam arranged to move with respect to each other in the longitudinal direction. The cross section of the lower beam is such that there is a groove-like open space at the bottom of the lower beam and a transfer cylinder between the lower beam and the upper beam is mounted in the groove.
