Dual bin high dump transport vehicle

A method of operating a transport vehicle comprising:

• providing a transport vehicle comprising:
• a main frame having a longitudinal axis, the main frame having a first end, a second end, and a pair of sides extending therebetween, wherein the first end of the main frame includes a trailer hitch;
• at least three axles, wherein each axle includes a pair of supports to support the main frame;
• a first assembly positioned at the first end of the main frame comprising:
• a first lifting frame parallel with the longitudinal axis of the main frame and extending upward;
• a first bin having an open top connected to the first lifting frame;
• a first bin lifting actuator connected to the first lifting frame and at the first bin at a first bin lifting pivot point;
• and
• a first bin tilting actuator connected to the first lifting frame and at the first bin at a first bin tilting pivot point,
• wherein, upon extension of the first bin lifting actuator and of the first bin tilting actuator, the first bin is raised from the main frame and rotated about the first bin lifting pivot point to at least partially invert the first bin toward a side of the main frame;
• a second assembly positioned at the second end of the main frame comprising:
• a second lifting frame parallel with the longitudinal axis of the main frame and extending upward;
• a second bin having an open top connected to the second lifting frame;
• a second bin lifting actuator connected to the second lifting frame and at the second bin at a second bin lifting pivot point;
• and
• a second bin tilting actuator connected to the second lifting frame and at the second bin at a second bin tilting pivot point,
• wherein, upon extension of the second bin lifting actuator and of the second bin tilting actuator, the second bin is raised from the main frame and rotated about the second bin lifting pivot point to at least partially invert the second bin toward the side of the main frame;
• at least one sensor configured to output a signal corresponding to a position of at least one of the first and second bins;
• and
• a hydraulic system in fluid communication with the lifting and tilting actuators of the first and second assemblies wherein the hydraulic system allows operation of only one of the first or second assemblies at a time, based at least in part on the signal output from the at least one sensor;
• extending the lifting and tilting actuator of the first assembly;
• raising the first bin from the main frame;
• and
• inverting the first bin to the side of the main frame.
