Abstract
A towable dump trailer is provided. The towable dump trailer comprises a first, second and third frame. The first frame comprises one or more sets of wheels. The second frame is attached to the tow vehicle and can be displaced horizontally relative to the first frame by the towing vehicle moving rearward or forward. The third frame provides a support frame for the trailer bed. The dump trailer is operated by immobilizing the first frame and causing the second frame to move horizontally relative to the first frame. This horizontal displacement causes the third frame to pivot as a result of one or more pivoting arms translating the horizontal movement to pivotal movement. The dump trailer can be configured to provide a dumping action by either forward or rearward horizontal displacement of the second frame relative to the first frame.
Claims20
A dump trailer comprising:
- a first frame, the first frame bearing one or more sets of wheels;
- a second frame, the second frame comprising an attachment device to permit coupling to a towing vehicle;
- a third frame positioned above the first and second frames and providing support for a trailer bed;
- one or more roller subassemblies positioned between the first frame and the second frame, wherein the roller subassemblies permit forward and rearward movement of the second frame relative to the first frame;
- one or more pivot subassemblies, wherein the one or more pivot subassemblies permit the third frame to pivot as the second frame moves forward and rearward relative to the first frame;
- one or more pivoting arms, wherein the one or more pivoting arms cause the third frame to pivot about the one or more pivot subassemblies as the second frame moves forward and rearward relative to the first frame.
A dump trailer comprising:
- a first frame, the first frame comprising a pair of longitudinal support beams, one or more lateral support beams disposed between the pair of longitudinal support beams, and one or more axles each bearing a set of wheels;
- a second frame positioned above the first frame, the second frame comprising a pair of longitudinal support beams, one or more lateral support beams disposed between the pair of longitudinal support beams, a tongue extending from each longitudinal support beam coupled to a hitch for attaching to a towing vehicle;
- a third frame positioned above the second frame, the third frame comprising a pair of longitudinal support beams, a plurality of lateral support beams disposed between the pair of longitudinal support beams;
- one or more roller subassemblies positioned between the first and second frames, wherein the roller subassemblies permit forward and rearward movement of the second frame relative to the first frame;
- one or more pivot subassemblies disposed between the second and third frames, wherein the one or more pivot subassemblies permit the third frame to pivot as the second frame moves forward and rearward relative to the first frame;
- one or more pivoting arms, wherein the one or more pivoting arms extend between the first frame and third frame, and wherein the one or more pivoting arms cause the third frame to pivot about the one or more pivot subassemblies as the second frame moves forward and rearward relative to the first frame.
A dump trailer comprising:
- a first frame, the first frame comprising a pair of parallel longitudinal support beams, one or more lateral support beams disposed between the pair of longitudinal support beams, and one or more axles each bearing a set of wheels;
- a second frame positioned below the first frame, the second frame comprising one or more longitudinal support beams and an attachment device for coupling to a towing vehicle;
- a third frame positioned above the first frame, the third frame comprising a pair of parallel longitudinal support beams, a plurality of lateral support beams disposed between the pair of parallel longitudinal support beams;
- one or more roller subassemblies positioned between the first and second frames, wherein the roller subassemblies permit forward and rearward movement of the second frame relative to the first frame;
- one or more pivot subassemblies disposed between the first and third frames, wherein the one or more pivot subassemblies permit the third frame to pivot as the second frame moves forward and rearward relative to the first frame;
- one or more pivoting arms, wherein the one or more pivoting arms extend between the second frame and third frame, and wherein the one or more pivoting arms cause the third frame to pivot about the one or more pivot subassemblies as the second frame moves forward and rearward relative to the first frame.
