A feed unit (105) to be used with a mining or construction machine (100), the feed unit (105) having a feeder holder (106) and a feed beam (111) able to move relative to the feeder holder (106), the feed unit (105) also having a supporting unit for a drilling machine (121), the supporting unit being arranged to support the drilling machine (121) moveably in relation to the feed beam (111), and the feed unit (105) having a driving device to move the feed beam (111) relative to the feeder holder (106) in operation. The supporting unit is attached to the feeder holder (106) such that, when the feed beam (111) moves relative to the feeder holder (106) by the driving device, the supporting unit is automatically moved at the same time along the feed beam (111). A rock drilling assembly and a rock drilling rig include the feed unit. |
