Abstract

A side dump body having an increased carrying capacity when compared to conventional side dump bodies with the side dump body being pivotally movable between transport, loading and dumping positions. The side dump body has an open upper end which is directed upwardly when the side dump body is in its transport position. When the side dump body is in its loading position, the open upper end of the side dump body is directed upwardly and laterally towards one side of the wheeled frame upon which the side dump body is pivotally mounted. When the side dump body is in its dumping position, the open upper end of the side dump body is directed laterally and downwardly from the side of the wheeled frame.

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 substantially vertically upwardly 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 third side wall extending substantially vertically upwardly from the upper end of said second side wall;

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

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

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

a first elongated rear link arm having upper and lower ends;

said lower end of said first rear link arm being pivotally secured to said wheeled frame adjacent said first side thereof at the rearward end thereof;

a second elongated rear link arm having upper and lower ends;

said lower end of said second rear link arm being pivotally secured to said wheeled frame adjacent said second side thereof at the rearward end thereof;

a third elongated rear link arm having first and second ends;

said first end of said third rear link arm being pivotally secured to said upper end of said first rear link arm;

said third rear link arm being pivotally secured, intermediate its length, to said upper end of said second rear link arm;

said third rear link arm being pivotally secured to said third side wall;

a first rear hydraulic cylinder pivotally connected to and extending between said wheeled frame and said first rear link arm;

a second rear hydraulic cylinder pivotally connected to and extending between said third rear link arm and said rear wall;

a first elongated front link arm having upper and lower ends;

said lower end of said first front link arm being pivotally secured to said wheeled frame adjacent said first side thereof at the forward end thereof;

a second elongated front link arm having upper and lower ends;

said lower end of said second front link arm being pivotally secured to said wheeled frame adjacent said second side thereof at the forward end thereof;

a third elongated front link arm having first and second ends;

said first end of said third front link arm being pivotally secured to said upper end of said first front link arm;

said third front link arm being pivotally secured, intermediate its length, to said upper end of said second front link arm;

said third front link arm being pivotally secured to said third side wall;

a first front hydraulic cylinder pivotally connected to and extending between said wheeled frame and said first front link arm;

a second front hydraulic cylinder pivotally connected to and extending between said third front link arm and said front wall;

the actuation of said hydraulic cylinders enabling said side dump body to be selectively movably positioned in a loading position, a transport position and a dumping position;

said side dump body, when in its said loading position, having its said second side wall substantially horizontally disposed on said wheeled frame so that said open upper end of said side dump body is directed generally toward said second side of said wheeled frame to facilitate the loading of material into said side dump body;

said side dump body, when in its said transport position, having its said bottom wall substantially horizontally disposed on said wheeled frame;

said side dump body, when in its said dumping position, having its said open upper end generally directed downwardly and laterally of said second side of said wheeled frame to dump the material in said side dump body therefrom laterally of said second side of said wheeled frame.

2. 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 substantially vertically upwardly 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 third side wall extending substantially vertically upwardly from the upper end of said second side wall;

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

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

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

a first hydraulically operated linkage pivotally connected to and extending between said rearward end of said side dump body and said wheeled frame;

a second hydraulically operated linkage pivotally connected to and extending between said forward end of said side dump body and said wheeled frame;

the actuation of said first and second hydraulically operated linkages enabling said side dump body to be selectively movably positioned in a loading position, a transport position and a dumping position;

said side dump body, when in its said loading position, having its said second side wall substantially horizontally disposed on said wheeled frame so that said open upper end of said side dump body is directed generally toward said second side of said wheeled frame to facilitate the loading of material into said side dump body;

said side dump body, when in its said transport position, having its said bottom wall substantially horizontally disposed on said wheeled frame;

said side dump body, when in its said dumping position, having its said open upper end generally directed downwardly and laterally of said second side of said wheeled frame to dump the material in said side dump body therefrom laterally of said second side of said wheeled frame.
