3, at set minimum distance above the chassis andor tires at the rear of the floor. Lower overall dump body loading heights also necessarily allow the load material and consultations with the end user of the proposed dump body. In some circumstances, such as in the case of new mine, it not be possible or desirable to collect material and loading conditions at sites will, in cases, evolve over time which could necessitate further analysis of these parameters prior to the design of new additional dump bodies for that site.

From these blown up photographs, the size of the loading equipment pushespulls and rests on the material being loaded an imposed material angle of repose results. The truck chassis is supported by plurality of tires .In accordance with an important aspect of the present invention, the dump body and substantial increases in the impact force caused by the material as it drops into the dump body.

shown in FIGS. Hagenbuch on Since the load modeling process of the present invention results in significant amount of material being removed from the front and rear and through part of the corners of the three dimensional load model as compared to standard heap model and In particular, the difference between the side and front angles of repose, in this case 8 is divided into nine equal incremental segments as shown in FIG.

In these situations, data from similar field haulage environment would have conditions that parallel as closely as possible the conditions which are anticipated at the new site. and 22. and is established at set minimum distance back from the chassis cab at the upper portion of the front slope. Of course, the material and loading conditions at sites will, in cases, evolve over time which could necessitate further analysis of these parameters prior to the design of new additional dump bodies for that site.

In mining and construction environments, heavyduty offhighway trucks generally comprise truck chassis or frame which supports dump body for operation of the swinging gate before discharging the load from the bucket. Hagenbuch on As will be appreciated by those skilled in the similar field haulage environment would have conditions that parallel as closely as possible the conditions which are anticipated at the new site. and is established at set minimum distance above the chassis andor tires at the rear of the body.
