Abstract
A method and a rod magazine for handling elongated rods in a rock drilling unit, and a bolting unit. Elongated rods, such as drill rods and rock bolts, are stored into a linear rod magazine—provided with feed members for transferring the rods upward and downward in the magazine. The feed members comprise screw surfaces by which the rods are supported in the magazine. The required feeding movement is produced by rotating the feed members about their rotation axis. In addition, the rod magazine comprises transfer means that allow the rods to be transferred from the magazine to a drilling line or bolting line, i.e. to a center, and vice versa. The transfer means are provided with gripping means for gripping the rods.
