Severe application off-highway truck body
First Claim
1. An open top body of an off-highway haulage vehicle for hauling abrasive material, the body comprising:
- a floor comprising at least two sections with a first forward section of the floor at one inclination and a second rearward section inclined at a different inclination angled more downwardly toward a ground surface than the inclination of the first section,opposing sidewalls extending vertically from the floor and horizontally from a front wall toward a rear of the floor such that the distance between the opposing sidewalls increases from the front wall to the rear of the floor; and
a tailgate pivotally attached to the sidewalls for rotation between closed and opened positions.

Abstract
An open top body of an off-highway haulage vehicle is described for severe hauling applications such as hauling of high density, abrasive material. The body has a floor divided into at least two sections with first and second sections angled at different inclinations. The second section extends to the rear edge of the floor and is at an angle of inclination greater than the first section. The opposing sidewalls of the body extend vertically from the floor are flared or taper along their length such that the body floor is wider at the rear of the body than it is at the front. The body includes a tailgate pivotally attached to the sidewalls for rotation between closed and opened positions in response to the bumping of the load by the body.

7. A method of dumping material from an open top body having opposing sidewalls extending vertically from a floor of the body and extending horizontally from a front wall of the body toward a rear of the floor such that the distance between the opposing sidewalls increases from the front wall to the rear of the floor, the method comprising:
-
tilting the body about an axis of rotation; rotating a tailgate to an open position in response to the tilting of the body; supporting material carried in the body at first and second angles of inclination along the floor of the body as the body is tilted such that the material flows from an area of the floor at a first angle to an area of the floor at the second angle of inclination, where the second angle is greater than the first angle such that the second angle inclines the floor more toward a ground surface than does the first angle; and laterally supporting the material carried by the body as it flows from the body as it is tilted such that the opposing sidewalls flare away from one another so as to relieve pressure of the material bearing against the sidewalls. - View Dependent Claims (8)
