The subject matter of the invention is an arrangement of the hydraulic lines of a hydraulic loading machine, comprising a supporting column (3) and a jib system with a rear jib (lifting jib 1), one end of which is pivotably connected to the column and the other end of which is pivotably connected to a front jib (level-luffing jib 2), the jibs being pivotable in relation to the column and in relation to one another by means of hydraulic cylinders (4, 5), and at least one hydraulic line (H), which consists at least partly of a flexible tube, extending from the column (3) up to and along the lifting jib (1) as well as up to and into the level-luffing jib (2). The invention is distinguished by the fact that the hydraulic line, over that section where it spans at least one of the two articulation points (30 and/or 31), has a length and radius of curvature which are dependent upon the pivoting angle at the articulation point and thus vary, and that the hydraulic line, in order to make possible the requisite changes in this length and this radius of curvature during changes in the pivoting angle at the articulation point, is arranged in such a way that it forms a tube loop (HB, HBY) at a point at a distance from the respective articulation point, which tube loop (HB, HBY) enables the hydraulic-line section spanning the articulation point to be shortened and lengthened, as a result of which tube loops at the articulation point can be eliminated. <IMAGE>
