Construction machine with pivotable boom

摘要

A construction machine with a pivotable boom, consisting of at least an upper arm and a working arm linked to it and provided with flexible lines for operating media, is to be improved by at least one bearing device (86) being provided to guide the flexible lines (37) on the boom (22). The bearing device (86) projects from the boom (22), is rotatable about a pivot screw (87) or suchlike hinge pin and has at least one passage (90), arranged eccentrically to the pivot screw, for the line(s). The bearing device (86) is to be arranged at a distance (t) from the hinge bolt (24) of the boom (22) on its working arm (30). <IMAGE>
