摘要： A shank sleeve assembly, a rock drilling machine, and a method. The assembly (26) is mountable around a shank adapter (8) in a rock drilling machine (6) and comprises a shank bushing (27) having two-piece configuration comprising a first bushing component (27a) and a second bushing component (27b) connectable against each other. The assembly further comprises a bearing bushing (30) arrangeable to surround the two-piece shank bushing and allowing rotation between the shank bushing and the bearing bushing.

摘要： An apparatus may control movement of a mining tool of a mining vehicle towards a mining tool magazine, wherein a light source is configured to emit light along a plane at a predetermined reference distance to the mining tool magazine; receive visual data comprising a representation of the mining tool; determine a distance between the mining tool and the mining tool magazine based on detecting, based on the visual data, illumination of a predetermined portion of the mining tool or the mining vehicle by the emitted light; monitor the distance between the mining tool and the mining tool magazine based on movement of the mining tool and/or the mining vehicle; and control replacement of at least a distal portion of the mining tool by another mining tool stored in the mining tool magazine based on the monitoring of the distance between the mining tool and the mining tool magazine.
