Abstract: A conversion kit for converting a lightweight dump truck into a sand and salt spreader, wherein a compact second dump body is provided which can be inserted in the first dump body. The second dump body has a first sub-frame overlying the floor of the first dump body and a second sub-frame pivotable about a longitudinal axis over the first sub-frame having a side wall along one edge and a conveyor extending along the hinge axis. A first piston and cylinder extends between the edge of the first sub-frame and the upper edge of the side wall of the second sub-frame to initiate the pivoting travel of the second sub-frame. The second piston and cylinder extends between a median point of the first sub-frame and the outer edge of the second sub-frame to continue the pivoting travel of the second sub-frame.

Abstract: A mounting bracket for mounting the rear post of a side wing plow is provided wherein the bracket is adapted to be mounted to the frame of the snow plowing vehicle. The side wing plow includes a rear post with a carriage for mounting the side wing plow. At least a semi-cylindrical member is located on the post on the opposite side and it has a longitudinal axis parallel to the post. The bracket mounted to the vheicle frame includes at least a concave arcuate seat member having a vertical axis for receiving the semi-cylindrical member such that the post can be rotated through a definite angle in the arcuate seat and the semi-cylindrical members are welded in the seat at an angle which has been selected for the particular vehicle on which the side wing plow has been mounted.

Abstract: A lightweight salt and sand spreader dump truck box having a first sub-frame with elongated longitudinal channel members formed from sheet metal and a conveyor frame on which a conveyor is mounted longitudinally of the dump box at the floor thereof near a side wall of the dump box, wherein the conveyor frame is integral with the sub-frame. A second sub-frame is pivoted about a longitudinal axis adjacent the conveyor frame on the opposite side from the first side frame member and includes a wall member which, when in a down position, is flush with a side frame member of the first sub-frame.
