Abstract:
A feeder holding device used with a rock drilling and/or rock bolting rig, in which the rock drilling and/or rock bolting rig has at least one boom with a first end and a second end, the first end is attached to a carrier, and the second end supports a feed beam by the feeder holding device, and in which the feed beam can be adjusted by the feeder holding device in a first drilling position in a first drilling direction and in a second position. The feeder holding device provides linear movement of the feed beam, in a direction different from the drilling direction, from the first drilling position to the second position, such that the feed beam in the second position is pointed in a direction parallel to the first drilling direction. A rock drilling and/or rock bolting rig is also provided.
