Abstract

A side dump body truck or trailer comprising a body pivotally mounted on a wheeled frame and fashioned so as to enable the material within the trailer body to be dumped from either side of the trailer. The body is constructed of rear, intermediate and front bulkheads having bottom wall and side wall portions in abutting relationship therewith and being welded thereto. The front and rear bulkheads are preferably angled upwardly and outwardly so as to increase the carrying capacity of the body. The bottom of the body is preferably V-shaped to increase the carrying capacity of the body.

Claims

1. A side dump apparatus, comprising:

an elongated wheeled frame having a forward end, a rearward end, and opposite sides;

a plurality of horizontally spaced-apart first supports on said wheeled frame at one side thereof;

a plurality of horizontally spaced-apart second supports on said wheeled frame at the other side thereof;

a side dump body movably positioned on said wheeled frame comprising rear, intermediate and front bulkheads with each of the bulkheads having front and rear sides;

substantially horizontally disposed front and rear bottom wall portions having front and rear edges;

first, second, third and fourth side wall portions having front and rear edges;

said side dump body being movable between transport and dumping positions;

said rear edges of said rear bottom wall portion and said first and second side wall portions abutting said front side of said rear bulkhead and being welded thereto;

said front edges of said rear bottom wall portion and said first and second side wall portions abutting said rear side of said intermediate bulkhead and being welded thereto;

said rear edges of said front bottom wall portion and said third and fourth side wall portions abutting said front side of said intermediate bulkhead and being welded thereto;

said front edges of said front bottom wall portion and said third and fourth side wall portions abutting said rear side of said front bulkhead and being welded thereto;

each of said rear, intermediate and front bulkheads having a first pivot plate portion extending laterally outwardly from one side thereof adjacent the lower end thereof;

each of said first pivot plate portions having a pivot pin associated therewith which is pivotally secured to one of said first supports;

each of said rear bulkhead, intermediate bulkhead and front bulkhead having a second pivot plate portion extending laterally outwardly from the other side thereof adjacent the lower end thereof;

each of said second pivot plate portions having a pivot pin associated therewith which is pivotally secured to one of said second supports on said wheeled frame;

and means operatively interconnecting said wheeled frame and said body for pivotally moving said body between its transport and dumping positions.

2. The side dump apparatus of claim 1 wherein said rear bulkhead extends upwardly and rearwardly from is lower end to its upper end.

3. The side dump apparatus of claim 1 wherein said front bulkhead extends upwardly and forwardly from its lower end to its upper end.

4. The side dump apparatus of claim 2 wherein said front bulkhead extends upwardly and forwardly from its lower end to its upper end.

5. The side dump apparatus of claim 1 wherein said front and rear bottom wall portions are generally V-shaped in cross-section.

6. The side dump apparatus of claim 1 wherein said means for pivotally moving said body comprises a first power cylinder positioned forwardly of said front bulkhead and having one end thereof pivotally secured to said wheeled frame and its other end pivotally secured to said front bulkhead at the upper end thereof and a second power cylinder positioned rearwardly of said rear bulkhead and having one end thereof pivotally secured to said wheeled frame and its other end pivotally secured to the upper end of said rear bulkhead.

7. The side dump apparatus of claim 1 wherein said first and second pivot plate portions are integrally formed with their respective bulkhead.

8. The side dump apparatus of claim 1 wherein said intermediate bulkhead has a central cut-away portion.

9. A side dump apparatus, comprising:

an elongated wheeled frame having a forward end, a rearward end, and opposite sides;

a plurality of horizontally spaced-apart first supports on said wheeled frame at one side thereof;

a plurality of horizontally spaced-apart second supports on said wheeled frame at the other side thereof;

a side dump body movably positioned on said wheeled frame comprising rear, intermediate and front bulkheads with each of the bulkheads having front and rear sides;

substantially horizontally disposed front and rear bottom wall portions having front and rear edges;

first, second, third and fourth side wall portions having front and rear edges;

said side dump body being movable between transport and dumping positions;

said rear edges of said rear bottom wall portion and said first and second side wall portions abutting said front side of said rear bulkhead and being welded thereto;

said front edges of said rear bottom wall portion and said first and second side wall portions abutting said rear side of said intermediate bulkhead and being welded thereto;

said rear edges of said front bottom wall portion and said third and fourth side wall portions abutting said front side of said intermediate bulkhead and being welded thereto;

said front edges of said front bottom wall portion and said third and fourth side wall portions abutting said rear side of said front bulkhead and being welded thereto;

each of said rear and front bulkheads having a first pivot plate portion extending laterally outwardly from one side thereof adjacent the lower end thereof;

each of said first pivot plate portions having a pivot pin associated therewith which is pivotally secured to one of said first supports;

each of said rear bulkhead and front bulkhead having a second pivot plate portion extending laterally outwardly from the other side thereof adjacent the lower end thereof;

each of said second pivot plate portions having a pivot pin associated therewith which is pivotally secured to one of said second supports on said wheeled frame;

and means operatively interconnecting said wheeled frame and said body for pivotally moving said body between its transport and dumping positions.

10. The side dump apparatus of claim 9 wherein said front and rear bottom wall portions are generally V-shaped in cross-section.

11. The side dump apparatus of claim 9 wherein said first and second pivot plate portions are integrally formed with their respective bulkhead.

12. The side dump apparatus of claim 9 wherein said intermediate bulkhead has a central cut-away portion.
