Abstract
A vehicle is shown having a hopper mounted thereon capable of dumping materials contained within the hopper over the end of the hopper or through the bottom of the hopper. Dumping over the end of the hopper is accomplished by lifting the front end of the hopper and sequentially pivoting the rear end of the hopper upon an initial pivot point and a subsequent pivot point in a manner which minimizes the risk of the vehicle capsizing by maintaining a low center of gravity. Dumping through the bottom of the hopper is accomplished through the use of a clam shell gate covering an opening in the bottom of the hopper. The vehicle may be interchangeably used as a rear dump vehicle or a belly dump vehicle, more safely used upon hazardous terrains, and still carry the maximum load capacity allowed.
Claims6
A combination belly dump/end dump vehicle for hauling material comprising:
- a frame mounted upon wheels, said frame containing a first pivot support and a second pivot support, wherein said first pivot support is at least level with or lower than said second pivot support;
- a hopper for containing said material, said hopper having gate means located upon a bottom thereof for dumping from a bottom side everything from said hopper and at least one telescopic hydraulic ram for raising a front end of said hopper, said telescopic hydraulic ram being attached to said hopper by hopper lifting means, a lower end of said hopper lifting means being rotatably attached to a front end of said hopper and an upper end of said hopper lifting means being rotatably attached to an upper end of said telescopic hydraulic ram,
- said hopper being located on said frame such that upon raising a front end of said hopper said material dumps out of a rear end of said hopper and over a rear of said frame, said hopper additionally comprising a first pivot means and a second pivot means, wherein said first and second pivot means alternately engage said first and second pivot supports of said frame and at least one of said pivot means engages at least one pivot support at all times during the dumping process.
