Claim:
A vehicle for transporting bulk material comprising: a dump body having a rounded base, two sidewalls, each of the two sidewalls having a straight interior surface that is flat, the sidewalls extending upward and outward from the rounded base to an upper edge region of the dump body at an angle that is acute to vertical, such that the dump body is laterally widened at the upper edge region of the sidewalls relative to the rounded base, and wherein only one side transition between the rounded base and each of the two sidewalls is provided, a front wall terminating the dump body at a front end of the rounded base, and a chute arranged at a rear end of the rounded base and being drawn diagonally upward with respect to the rounded base, wherein a rear transition between the rounded base and the chute is rounded, and wherein the rounded base of the dump body maintains its cross-sectional shape consistently from the front wall to the rear transition of the chute, and where an exit base of the chute is non-rounded; and two piston-in-cylinder assemblies extendable to drive the dump body between a support position and an upwardly pivoted ejection position, each of the two piston-in-cylinder assemblies having a first end attached to the vehicle and a second end attached to an upper exterior of the sidewalls of the dump body; wherein the dump body is secured to the vehicle by at least the two piston-in-cylinder assemblies and a pivot positioned rearward of a rear axle of the vehicle, the pivot being positioned below and rearward of the rear transition between the rounded base and the chute of the dump body and ahead of a rear end of the dump body, wherein the dump body pivots between the support position and the upwardly pivoted ejection position and a pivot axis of the dump body is located at the pivot.
