Abstract
An elongated tub includes a first end and a second end opposite the first end. An A-frame structure includes a force transfer vertex positioned adjacent to a top portion of the first end, a first pivot vertex pivotally and releasably coupled to an elongated frame, and a second pivot vertex pivotally and releasably coupled to the elongated frame. The A-frame structure includes a first force transfer beam coupled to the first end and coupled between the force transfer vertex and the first pivot vertex, a second force transfer beam coupled to the first end and coupled between the force transfer vertex and the second pivot vertex, and a separation beam coupled to the first pivot vertex and the second pivot vertex.
Claims20
An apparatus comprising:
- an elongated frame;
- an elongated tub having:
- an open top,
- a first side,
- a second side opposite the first side,
- a first end extending between an edge of the first side and an edge of the second side,
- a second end opposite the first end;
- and
- a base side opposite the open top;
- an A-frame structure having:
- a force transfer vertex positioned adjacent to a top portion of the first end,
- a first pivot vertex pivotally and releasably coupled to the elongated frame,
- a second pivot vertex pivotally and releasably coupled to the elongated frame,
- a first force transfer beam coupled to the first end and coupled between the force transfer vertex and the first pivot vertex,
- a second force transfer beam coupled to the first end and coupled between the force transfer vertex and the second pivot vertex, and
- a separation beam coupled to the first pivot vertex and the second pivot vertex;
- a hydraulic assembly having a cylinder and a rod that is telescoped at least partially within the cylinder;
- wherein the cylinder is pivotally coupled to the elongated frame;
- and
- wherein the rod is pivotally coupled to the force transfer vertex.
An apparatus comprising:
- an A-frame structure having:
- a force transfer vertex,
- a first pivot vertex,
- a second pivot vertex,
- a first force transfer beam coupled between the force transfer vertex and the first pivot vertex,
- a second force transfer beam coupled to the first end and coupled between the force transfer vertex and the second pivot vertex, and
- a separation beam coupled to the first pivot vertex and the second pivot vertex;
- a hydraulic assembly having a cylinder and a rod that is telescoped at least partially within the cylinder;
- and
- wherein the rod is pivotally coupled to the force transfer vertex.
A method comprising:
- coupling an elongated tub to an elongated frame by coupling a first set of mounting clasps to a first set of pivot hooks and by coupling a second set of mounting clasps to a second set of pivot hooks;
- mounting an A-frame structure to a first end of an elongated tub, the A-frame structure having:
- a first pivot vertex pivotally and releasably coupled to the elongated frame,
- a second pivot vertex pivotally and releasably coupled to the elongated frame,
- a force transfer vertex,
- a first force transfer beam coupling the first pivot vertex to the force transfer vertex, and
- a second force transfer beam coupling the second pivot vertex to the force transfer vertex;
- uncoupling the first pivot vertex from the elongated frame;
- uncoupling the first set of mounting clasps from the first set of pivot hooks;
- and
- applying force to the force transfer vertex;
- wherein the force applied to the force transfer vertex is directed along the first force transfer beam to the first pivot vertex and along the second transfer beam to the second pivot vertex, causing the force transfer vertex to move in an arc about the second pivot vertex, causing the elongated tub to pivot from a transport position, in which an open top is facing upward, to a dumping position in which the open top is facing away from one side of the elongated frame.
The method of claim 20 wherein applying the force comprises:
- applying force below a centroid of the first end of the elongated tub.
The method of claim 20 wherein applying the force comprises:
- applying force to a lower portion of a mounting frame, wherein the lower portion of the mounting frame is coupled to a lower portion of the first end of the elongated tub.
