Dump truck body

A modular truck body comprises unitary first and second modules having bottom sections thereof secured together at a separation line which is substantially offset laterally from a longitudinal axis of the truck body. The width of the first module is thus substantially larger than the width of the second module. The modules are aligned and preassembled at a manufacturing plant by releasably securing them together at the separation line therebetween. The modules are then disassembled and shipped to a remote job site or the like for final reassembly and securance of the modules together.

Method of making a modular truck body

Modular truck body

A corner joint is provided which includes a first assembly which has a protrusion and a second assembly which has a rib. The rib has a flange portion welded to a respective protrusion. The flange is positioned about the protrusion and movable along said protrusion to said weld position.

Truck body corner joint

Apparatus for controlling the operation of dump doors of a wagon or the like, permitting the operator to set a control lever selectively in a closed or open position, with the apparatus effecting the desired selective movement of the doors and returning the control lever to a 'Hold' position upon completion of the desired movement. The apparatus includes a cam device responsive to the movement of the doors to the selected position for releasing the control lever and thereby terminating the driving of the doors to the selected position. The apparatus alternatively may provide a single full movement of the doors or a sequential movement, as desired.

Wagon door control system and dual cam therefor

A modular truck body comprises a pair of upstanding side modules each having an L-shaped cross section, a bottom module having its outer edges secured to inner edges of the side modules and an upstanding front module secured between the side modules and having its lower edge secured to the bottom module. The modules are aligned and pre-assembled at a manufacturing plant and then disassembled for shipping purposes. At a customer's job site or the like the modules are re-assembled and secured together for installation on the frame of a truck.
