ABSTRACT:
A wheeled vehicle structure including a frame having laterally spaced rail portions, a working component such as a loader, and arm and control cylinder structure attached to the working component for selective positioning thereof. A prefabricated tower assembly is mounted to the frame in straddling relationship to the spaced rails, with a top portion of the tower assembly resting on a top surface of the rails and a lower side portion of the tower assembly welded to the outer side surfaces of the rails. Shims are provided for accurately locating the tower assembly transversely of the frame and to accommodate for manufacturing tolerances. The tower assembly includes pivot structure for pivotally connecting the arm and control cylinder structure thereto so as to permit ready conversion of the wheeled vehicle to a loader or the like. The tower assembly is fully prefabricated and machined prior to being secured to the vehicle frame and serves to provide improved distribution of the working component loads into the frame.
