Abstract

In a loader attachment (1) for a working vehicle such as an agricultural tractor, there are arranged at least two arms (4), produced in the form of hollow bodies, which extend substantially in parallel, and at least one transverse hollow strut (6), for connecting the said arms (4). Electrical lines and/or fluid-carrying inlet lines (7) are run in at least one of the said arms (4). The transverse strut (6) and/or the arms (4) form an interconnected installation space in which is mounted at least one component (8) for controlling the loader attachment (1) or implements fastened to the front (3) thereof. The control components (8) are mounted on a carrier member 10 located in the transverse strut (6). The design avoids weakening the cross-sectional geometry of the arms or transverse strut and prevents the supply lines and control components from becoming fouled, without the need for additional protective components.
