Abstract

A side dump body including a plurality of side dump body units pivotally mounted on a truck or trailer frame. Each of the side dump body units may be individually pivotally moved from a transport position to a dumping position whereby the contents of the dump body units may be dumped from the side of the truck or trailer.

Claims

1. In combination:

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

a first upstanding support having upper and lower ends;

said first support secured to said first frame member and extending upwardly therefrom;

a second upstanding support having upper and lower ends;

said second support secured to said first frame member and extending upwardly therefrom in a spaced-apart relationship with respect to said first support;

a dump body positioned between said first and second supports and being movable from a transport position to a dumping position;

said dump body including a front wall, a back wall, a bottom wall, and first and second side walls;

said upper end of said first support being pivotally secured to said back wall adjacent said first side wall;

said upper end of said second support being pivotally secured to said front wall adjacent said first side wall;

a first elongated hydraulic cylinder, having upper and lower ends, operatively pivotally secured at its lower end to said frame means and extending upwardly therefrom;

said upper end of said first hydraulic cylinder being pivotally secured to said back wall laterally inwardly of the pivotal connection of said first support and said back wall;

a second elongated hydraulic cylinder, having upper and lower ends, operatively pivotally secured at its lower end to said frame means and extending upwardly therefrom;

said upper end of said second hydraulic cylinder being pivotally secured to said front wall laterally inwardly of the pivotal connection of said second support and said front wall;

said first and second hydraulic cylinders normally being in a retracted condition, but being movable to an extended position whereby said dump body will pivotally move with respect to said first and second supports and will pivotally move laterally with respect to a longitudinal axis of said frame means from its transport position to its dumping position so that material in said body will be dumped therefrom laterally of said frame means;

said first side wall including a lower end portion which extends upwardly and outwardly from said bottom wall and an upper end portion which extends upwardly from an upper end of said lower end portion.

2. The combination of claim 1 wherein said upper end portion of said first side wall is substantially vertically disposed when said body is in its transport position.

3. The combination of claim 2 wherein said second wall is substantially vertically disposed when said body is in its transport position.

4. In combination:

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

said frame means including first and second elongated, longitudinally extending frame members;

a first upstanding support having upper and lower ends;

said first support secured to said first frame member and extending upwardly therefrom;

a second upstanding support having upper and lower ends;

said second support secured to said first frame member and extending upwardly therefrom in a spaced-apart relationship with respect to said first support;

a dump body positioned between said first and second supports and being movable from a transport position to a dumping position;

said dump body including a front wall, a back wall, a bottom wall, and first and second side walls;

said upper end of said first support being pivotally secured to said back wall adjacent said first side wall;

said upper end of said second support being pivotally secured to said front wall adjacent said first side wall;

a first elongated hydraulic cylinder, having upper and lower ends, operatively pivotally secured at its lower end to said frame means and extending upwardly therefrom;

said upper end of said first hydraulic cylinder being pivotally secured to said back wall laterally inwardly of the pivotal connection of said first support and said back wall;

a second elongated hydraulic cylinder, having upper and lower ends, operatively pivotally secured at its lower end to said frame means and extending upwardly therefrom;

said upper end of said second hydraulic cylinder being pivotally secured to said front wall laterally inwardly of the pivotal connection of said second support and said front wall;

said first and second hydraulic cylinders normally being in a retracted condition, but being movable to an extended position whereby said dump body will pivotally move with respect to said first and second supports and will pivotally move laterally with respect to a longitudinal axis of said frame means from its transport position to its dumping position so that material in said body will be dumped therefrom laterally of said frame means;

a first brace member, having upper and lower ends, secured at its lower end to said frame means and extending upwardly and outwardly therefrom;

said upper end of said first brace member being secured to said first support;

a second brace member, having upper and lower ends, secured at its lower end to said frame means and extending upwardly and outwardly therefrom;

said upper end of said second brace member being secured to said second support.

5. In combination:

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

said frame means including first and second elongated, longitudinally extending frame members;

a first upstanding support having upper and lower ends;

said first support secured to said first frame member and extending upwardly therefrom;

a second upstanding support having upper and lower ends;

said second support secured to said first frame member and extending upwardly therefrom in a spaced-apart relationship with respect to said first support;

a dump body positioned between said first and second supports and being movable from a transport position to a dumping position;

said dump body including a front wall, a back wall, a bottom wall, and first and second side walls;

said upper end of said first support being pivotally secured to said back wall adjacent said first side wall;

said upper end of said second support being pivotally secured to said front wall adjacent said first side wall;

a first elongated hydraulic cylinder, having upper and lower ends, operatively pivotally secured at its lower end to said frame means and extending upwardly therefrom;

said upper end of said first hydraulic cylinder being pivotally secured to said back wall laterally inwardly of the pivotal connection of said first support and said back wall;

a second elongated hydraulic cylinder, having upper and lower ends, operatively pivotally secured at its lower end to said frame means and extending upwardly therefrom;

said upper end of said second hydraulic cylinder being pivotally secured to said front wall laterally inwardly of the pivotal connection of said second support and said front wall;

said first and second hydraulic cylinders normally being in a retracted condition, but being movable to an extended position whereby said dump body will pivotally move with respect to said first and second supports and will pivotally move laterally with respect to a longitudinal axis of said frame means from its transport position to its dumping position so that material in said body will be dumped therefrom laterally of said frame means;

a first connecting arm extending between the pivotal connection of said first support with said back wall and the pivotal connection of said first hydraulic cylinder with said back wall;

a second connecting arm extending between the pivotal connection of said second support with said front wall and the pivotal connection of said second hydraulic cylinder with said front wall.
