Abstract

The present disclosure relates to a dump body for a transport vehicle, in particular for the transportation of bulk material, which can be pivoted around a pivot axis between a support position and an upwardly pivoted ejection position by means of a drive device and which consists of a body preferably made of sheet metal and having a base, side walls, a front wall terminating the dump body at one end and a chute arranged at the oppositely disposed end and drawn upwardly with respect to the base, wherein the body is rounded in a parabolic manner, with it having a rounded body base, a rounded chute and a rounded transition between the body base and the chute.

Claims

1. 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, including at the upper edge region of the dump body, 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 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 transition between the rounded base and the chute is 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 transport 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 hinge assembly positioned rearward of a rear axle of the vehicle, a dump body portion of the hinge assembly being positioned rearward of the transition between the rounded base and the chute, wherein the dump body pivots between the support position and the upwardly pivoted ejection position and a pivot point of the dump body is located at the hinge assembly.

2. The vehicle of claim 1, wherein an exterior surface of the dump body is substantially free of welded reinforcement members.

3. The vehicle of claim 1, wherein the rounded body is rolled.

4. The vehicle of claim 1, wherein the rounded body is multi-bent.
