Method for attaching protective structure to feed beam, and protective structure in rock drilling rig |
摘要 |
A method for attaching a protective structure to a feed beam of a rock drilling rig, and a protective structure for a rock drilling rig. The protective structure is at least partly arranged around the feed beam so that as the feed beam bends in a bending direction of its longitudinal axis and/or twists about its longitudinal axis in a twisting direction, the protective structure substantially maintains its original shape. |
