Abstract

A strengthening rail is provided for use on the side dump body of a side dump trailer or truck. A strengthening rail is positioned at the exterior surface of the side walls of the body at the upper ends thereof. Preferably, each of the rails includes a lip portion at the upper end thereof which is positioned adjacent the exterior surface of the respective side wall. An upper end portion extends downwardly and outwardly from the upper end of the lip portion and terminates in a first wall portion which extends downwardly therefrom at an acute angle with respective side wall. A second wall portion extends downwardly and inwardly from the lower end of the first wall portion and terminates in a third wall portion which extends inwardly to the respective side wall. The inner end of the third wall portion is welded full length to the respective side wall. The inner end of the upper end portion of the side rail is also welded full length to the respective side wall.

Claims

1. In combination:

a wheeled frame having a forward end, a rearward end, a first side and a second side;

a side dump body movably mounted on said wheeled frame and having a rearward end, a forward end and an open upper end;

said side dump body including a bottom wall having first and second sides, a forward end and a rearward end;

a first side wall extending upwardly and outwardly from said first side of said bottom wall;

a second side wall extending upwardly and outwardly from said second side of said bottom wall;

a rear wall secured to and extending between said bottom wall, said first side wall and said second side wall;

a front wall secured to and extending between said bottom wall, said first side wall and said second side wall;

the upper ends of said first side wall, said second side wall, said front wall and said rear wall defining said open upper end of said side dump body;

each of said first and second side walls having interior and exterior surfaces and an upper end;

a first power cylinder having a base end pivotally secured to said wheeled frame intermediate the sides thereof forwardly of said body and a rod end operatively pivotally secured to said front wall of said body intermediate the sides thereof;

a second power cylinder having a base end pivotally secured to said wheeled frame intermediate the sides thereof rearwardly of said body and a rod end operatively pivotally secured to said rear wall of said body intermediate the sides thereof;

means for simultaneously selectively extending the rods of said first and second power cylinders whereby said body may dump material therein from at least one side of said body;

each of said first and second side walls having a stiffening rail mounted on the exterior surface thereof adjacent the upper end thereof;

each of said stiffening rails comprising an elongated plate which has been bent to define a first wall portion, having upper and lower ends, which extends downwardly from the respective side wall at an acute angle with respect to a plane of the respective side wall;

a second wall portion, having upper and lower ends, which extends downwardly from said lower end of said first wall portion at an obtuse angle with respect thereto; and

a third wall portion, having first and second ends, extending inwardly from said lower end of said second wall portion towards the respective side wall at an obtuse angle with respect to said second wall portion;

said upper end of said first wall portion being welded to the respective side wall;

said second end of said third wall portion being welded to the exterior surface of the respective side wall.

2. The combination of claim 1 wherein said first wall portion is welded full length to the respective side wall.

3. The combination of claim 1 wherein said second end of said third wall portion is welded full length to the respective side wall.

4. The combination of claim 2 wherein said second end of said third wall portion is welded full length to the respective side wall.

5. The combination of claim 1 wherein said open upper end includes a downwardly extending lip portion which is positioned adjacent the exterior surface of the respective side wall.

6. The combination of claim 1 wherein said open upper end comprises a fourth wall portion, having inner and outer ends, which extends upwardly from said upper end of said first wall portion towards the respective side wall and a downwardly extending lip portion at said inner end of said fourth wall portion which is positioned adjacent the exterior surface of the respective side wall.

7. The combination of claim 6 wherein said upper end portion is welded to the respective side wall at the juncture of said fourth wall portion and said lip portion.

16. The combination of claim 1 wherein said body has only one said stiffening rail secured to each of said side walls.

8. In combination:

a wheeled frame having a forward end, a rearward end, a first side and a second side;

a side dump body movably mounted on said wheeled frame and having a rearward end, a forward end and an open upper end;

said side dump body including a bottom wall having first and second sides, a forward end and a rearward end;

a first side wall extending upwardly and outwardly from said first side of said bottom wall;

a second side wall extending upwardly and outwardly from said second side of said bottom wall;

a rear wall secured to and extending between said bottom wall, said first side wall and said second side wall;

a front wall secured to and extending between said bottom wall, said first side wall and said second side wall;

the upper ends of said first side wall, said second side wall, said front wall and said rear wall defining said open upper end of said side dump body;

each of said first and second side walls having interior and exterior surfaces and an upper end;

a first power cylinder having a base end pivotally secured to said wheeled frame intermediate the sides thereof forwardly of said body and a rod end operatively pivotally secured to said front wall of said body intermediate the sides thereof;

a second power cylinder having a base end pivotally secured to said wheeled frame intermediate the sides thereof rearwardly of said body and a rod end operatively pivotally secured to said rear wall of said body intermediate the sides thereof;

means for simultaneously selectively extending the rods of said first and second power cylinders whereby said body may dump material therein from at least one side of said body;

each of said first and second side walls having a stiffening rail mounted on the exterior surface thereof adjacent the upper end thereof;

each of said stiffening rails comprising an elongated plate which has been bent to define an upper end portion, a first wall portion, having upper and lower ends, which extends downwardly from said upper end portion at an acute angle with respect to a plane of the respective side wall;

a second wall portion, having upper and lower ends, which extends downwardly from said lower end of said first wall portion at an obtuse angle with respect thereto; and

a third wall portion, having first and second ends, extending inwardly from said lower end of said second wall portion towards the respective side wall at an obtuse angle with respect to said second wall portion;
