Abstract

A laterally tiltable truck or trailer dump body with hinged side panels and hydraulically operated means for tilting the body laterally in the desired direction and for opening the side panel on the lower tilted side. The hydraulically operated means can also lift the dump body to a higher elevation in case the unloading area is at a height where this would be required. The hydraulic controls are preferably in the cab of the truck where they can be readily manipulated by the operator.

Claims

1. A vehicle having a frame:

a. a dump body mounted on said frame and having at least one transversely extending plate depending below the bottom of said body;

b. said frame having a housing for receiving said transversely extending plate when said dump body rests on said frame, said housing having side walls with inwardly extending flanges at their upper ends;

c. the ends of said transversely extending plate having hook-shaped portions that slidably contact with the inner surfaces of the housing side walls;

d. hydraulic means for tilting said dump body laterally either to the right or to the left so as to incline the dump body from a horizontal position, said means including hydraulic cylinders with telescopic piston rods; and

e. hydraulic valve controlled means for delivering added fluid to said cylinders for raising said dump body to a higher elevation, the operator controlling said valves for causing the desired hook-shaped portion of said plate to engage with its associate inwardly extending flange for stopping the raising of this end of said transverse plate;

f. whereby the hydraulic means will act on said dump body to cause it to swing about the engaged hook-shaped portion and to tilt said body laterally into dumping position.

2. The combination as set forth in claim 1:

and in which

a. said body having a left and a right side gate hingedly connected to the two side edges of the body;

b. hydraulic means for swinging the left side gate into open position when said dump body is tilted laterally to the left, and for swinging the right side gate into open position when said dump body is tilted laterally to the right; and

c. hydraulic valve controlled means for operating said side gates for causing the side gate on the lower side of said dump body to swing into open position when said dump body is swung into a laterally inclined position.

3. The combination as set forth in claim 1:

and in which

a. the hydraulic cylinders of said hydraulic means for tilting said dump body laterally being pivotally mounted within said housing and having their telescopic piston rods pivotally associated with said transversely extending plate;

b. whereby said hydraulic valve controlled means can be actuated by an operator for delivering fluid under pressure to said cylinders for causing said telescopic pistons to tilt said dump body laterally either to the right or to the left, or he can deliver additional fluid to said cylinders for raising said dump body to a higher elevation until the desired hook-shaped end of said transverse plate engages with its associate flange whereupon said plate will fulcrum about this flange as said piston rods swing said dump body laterally into a dumping position.

4. The combination as set forth in claim 3:

and in which

a. said body having a left and a right side gate hingedly connected to the two side edges of the body;

b. hydraulic means for swinging the left side gate into open position when said dump body is tilted laterally to the left, and for swinging the right side gate into open position when said dump body is tilted laterally to the right; and

c. hydraulic valve controlled means for operating said side gates for causing the side gate on the lower side of said dump body to swing into open position when said dump body is swung into a laterally inclined position.
