Abstract:
1. A mini-sized side dump trailer adapted to be pulled by a small vehicle, comprising: an elongated trailer frame having a forward end, a rearward end, a first side and a second side; a pair of wheels which support the frame at the rearward end thereof; a steerable wheel assembly which supports the frame at the forward end thereof; an elongated tongue having rearward and forward ends; said tongue being secured at its rearward end to said steerable wheel assembly and extending forwardly therefrom; said forward end of said tongue adapted to be secured to the small vehicle; a side dump body having rearward and forward ends, a first side and a second side movably mounted on said trailer frame and including a bottom wall, first and second side walls, a forward end wall, a rearward end wall and an open upper end; said forward end wall having first and second frames members secured thereto, having upper and lower ends, which define an inverted V-shape; a first longitudinally extending hinge pin secured to said lower end of said first frame member; a second longitudinally extending hinge pin secured to said lower end of said second frame member; said rearward end wall having third and fourth frame members secured thereto, having upper and lower ends, which define an inverted V-shape; a third longitudinally extending hinge pin secured to said lower end of said third frame member; a fourth longitudinally extending hinge pin secured to said lower end of said fourth frame member; a first hinge pin receptacle mounted on said frame adjacent the forward end thereof at said first side thereof; a second hinge pin receptacle mounted on said frame adjacent the forward end thereof at said second side thereof; a third hinge pin receptacle mounted on said frame adjacent the rearward end thereof at said first side thereof; a fourth hinge pin receptacle mounted on said frame adjacent the rearward end thereof at said second side thereof; said first, second, third and fourth hinge pin receptacles adapted to selectively receive said first, second, third and fourth hinge pins therein respectively; each of said hinge pin receptacles having a locking mechanism associated therewith which is movable between locked and unlocked positions; each of said locking mechanisms maintaining the associated hinge pin in the associated hinge pin receptacle when in its said locked position; each of said locking mechanisms permitting the associated hinge pin in the associated hinge pin receptacle to move out of engagement therewith when in its said unlocked position; a forward hydraulic cylinder positioned forwardly of said forward end wall and having a base end pivotally secured to said frame and a rod end pivotally secured to said forward end wall; a rearward hydraulic cylinder positioned rearwardly of said rearward end wall and having a base end pivotally secured to said frame and a rod end pivotally secured to said rearward end wall; the extension of said first and second hydraulic cylinder causing said side dump body to be pivotally moved to a first side dumping position when said first and third hinge pins are locked into said first and third hinge pin receptacles respectively and said second and fourth hinge pins are not locked into said second and fourth hinge pin receptacles respectively by said second and fourth locking mechanisms; the extension of said first and second hydraulic cylinders causing said side dump body to be pivotally moved to a second side dumping position when said second and fourth hinge pins are locked into said second and fourth hinge pin receptacles respectively by said second and fourth locking mechanisms and said first and third hinge pins are not locked into said first and third hinge pin receptacles respectively; and a power means on said frame for supplying hydraulic fluid to said hydraulic cylinders; said power means positioned on said trailer frame; each of said forward and rearward hydraulic cylinders having first and second inlet or outlet ports and wherein said power means includes a 12-volt DC battery, a 12-volt DC motor electrically connected to said battery, a hydraulic pump driven by said motor and having an inlet port and an outlet port, a hydraulic reservoir having an inlet port and an outlet port, said outlet port of said reservoir being fluidly connected to said inlet port of said pump, an electrically operated valve means including a first inlet port fluidly connected to said outlet port of said pump, a second inlet or outlet port, a third inlet or outlet port, and an outlet port which is fluidly connected to said inlet port of said reservoir, said second inlet or outlet port of said valve means being fluidly connected to each of said first inlet or outlet ports of said first and second hydraulic cylinders, said third inlet or outlet port being fluidly connected to each of said second inlet/outlet ports of said first and second hydraulic cylinders; the vehicle including a hydraulic pump system; said valve means including a fifth inlet port and a sixth outlet port which may be fluidly connected to the vehicle hydraulic pump system.
