Dump body structure for an off-highway truck
First Claim
1. A weld joint for a skeletal structure of an off-highway truck body, said skeletal structure having a plurality of longitudinal ribs and vertical ribs, said longitudinal and vertical ribs having at least one side leg and an exterior leg adjacent to said at least one side leg, said longitudinal and vertical ribs being connected by said weld joint, said weld joint comprising:
- a cutout portion disposed in said exterior leg of said longitudinal rib, said cutout portion positioned at an intersection of a vertical rib;
a tab portion defined on said exterior leg of said vertical rib, said tab portion extending beyond said at least one side leg, said tab portion being adapted to interfit said cutout portion and defining a groove between said cutout portion and said tab portion;
said exterior leg of said longitudinal rib and said vertical rib being disposed on a single planer surface; and
a weld deposited in said groove, said weld joining said exterior leg of said longitudinal rib and said exterior leg of said vertical rib.

Abstract
The present invention provides a dump body having an improved skeletal structure reinforcing the body. The skeletal structure includes a plurality of longitudinal and vertical ribs. The ribs include at least one side leg and an exterior leg adjacent to the side leg. A cutout portion is defined in the exterior leg of the longitudinal legs. The cutout portion is adapted to receive a tab portion of a corresponding vertical rib. The exterior legs of the longitudinal ribs and vertical ribs are defined on a single plane. At the intersection of each cutout portion and tab portion a groove is defined. The groove is adapted to receive a weld of substantially similar mechanical properties of the rib material.
