OFF-HIGHWAY TRUCK FRAME A truck frame (100) for use hauling heavy loads in a dump body (14) pivotally attached thereto utilizes a first beam (102) as a central spline for the truck (10). The first beam (102) is constructed by welding steel sheeting together around a plurality of support gussets (124). A pyramidal structure (102) connects this first beam (102) to a second beam (106). A pair of outriggers (110) extend from the second beam (106). The front suspension attaches the front wheels (16) of the truck (10) to the frame (100). The rear wheels (18) attach to the distal end of the first beam (102c) by the rear suspension (24). A cab support structure (120) extends across the proximal end of the first beam (102a). The monobeam construction allows for the use of two engines (30) mounted on either side of the first beam (102). If two engines are used, a second pair of outriggers (130) are utilized for support.
