发明名称 METHOD FOR ATTACHING PROTECTIVE STRUCTURE TO FEED BEAM, AND PROTECTIVE STRUCTURE IN ROCK DRILLING RIG
摘要 <p>A method for attaching a protective structure (7) to a feed beam (6) of a rock drilling rig, and a protective structure (7) for a rock drilling rig. The protective structure (7) is at least partly arranged around the feed beam (6) so that as the feed beam (6) bends in a bending direction (B) of its longitudinal axis and/or twists about its longitudinal axis in a twisting direction (A), the protective structure (7) substantially maintains its original shape.</p>
