Abstract

A method is provided for loading material into a dump body of a truck using a loading bucket whose volumetric capacity is approximately ⅓ or more than that of the dump body. The loading bucket is filled with an amount of earthen material and centered over the dump body. The bucket is then lowered to a position that: (1) substantially minimizes the clearance between the floor of the dump body and a swinging gate of the loading bucket in its freed position; (2) allows the swinging gate to clear the side walls of the dump body as it swings through an arc after it is freed, and (3) allows the material to be discharged substantially in the center of the dump body. After it is positioned, the swinging gate is then freed so as to release the material held in the bucket.

Claims

1. A body of a vehicle for hauling material, the body made by the following process:

(a) determining the desired load distribution of weight on a chassis of the haulage vehicle;

(b) determining the desired volumetric capacity for the body;

(c) establishing a line for a floor, a line for a front wall of the body and an inside body width;

(d) developing a three dimensional model of the hauled material carried in the body, including modeling corner voids of the hauled material, using data collected from an anticipated point of use with the three dimensional model of the hauled material having a distribution of weight on the chassis;

(e) adjusting a set of design parameters of the body until the three dimensional model distribution of weight on the chassis is substantially similar to the desired distribution of weight on the chassis and the volumetric capacity of the body is substantially similar to the desired volumetric capacity, including curving a rear edge of the floor to correspond with rear corner voids in the three-dimensional model; and

(f) producing the body in accordance with the set of design parameters.

2. The body of claim 1, wherein the developing the three-dimensional model of a heaped load includes determining a height of a top load plateau profile of the three-dimensional model.

3. The body of claim 1, wherein the collected data includes at least one material angle of repose of a heaped load to be carried by the body.

4. The body of claim 1, wherein the body is a truck body.

5. The body of claim 4, wherein the truck body has an open rear end.

6. The body of claim 4, wherein the truck body has an open top.
