Abstract: An improved slope plate assembly is provided for a truck box for use in transporting particulate material. The slope plate assembly include a plurality of slope plate sections pivotally connected to the opposite side walls of the truck box so as to be movable between a raised inoperative position and a lowered operative position. In the lowered position, particulate material flows by gravity along the slope plate sections for discharge into an auger assembly residing below the floor of the truck box. In the raised position, bulk material or other cargo can be loaded into the truck box. A multiple-piece dividing wall can also be installed in the truck box to divide the box into multiple compartments, with the slope plates being in the lowered position in the forward compartment and in the raised position in the rearward compartment, such that particulate material may be transported in the forward compartment and bulk material transported in the rearward compartment.

Abstract: A truck frame beam has an elongated vertically disposed web member having inner and outer surfaces and upper and lower ends with a support member on the upper end of the web member, and a foot portion on the lower end of the web member. The support surfaces are angularly disposed with respect to the web member and are comprised of a first surface that extends downwardly and inwardly from the web member, and a second surface that extends upwardly and outwardly with respect to the first surface. The two surfaces are offset with respect to each other, and an elongated channel indentation is positioned between the two support surfaces to receive the cylindrical portion of a hinge element.
