Abstract: A dump body for handling bulk material in which the tail gate is located inside the body walls sufficiently forward of the rear end to provide a delivery chute. The body is adapted to be mounted with the tail gate essentially over the rear wheels and the discharge chute extending back therefrom. Body configuration may be elliptical or rectangular and the sidewalls continuously diverge from bottom to top. The gate is hinged by overhead relatively close-tolerance bearings and trunnions by which the gate is hung and a space is provided between the gate edge and body wall even when fully closed, the space being filled with a flexible seal mounted on the gate perimeter. Specially shaped stops are located on the inner sidewall against which the gate butts on closing. A remotely actuated latch mounted on the body extends through the body wall extension to engage and lock the gate.
