Work vehicle

A vehicle for operation with a load and controlled by an operator, the vehicle comprising:

• a chassis having a longitudinal axis symmetrically dividing the chassis through its middle;
• a cabin fixedly mounted on a first side of the longitudinal axis of the chassis on a forward portion thereof, the operator positioned in the cabin if operating the vehicle;
• a plurality of wheels coupled to the chassis, including front and real wheels, to movably support the chassis;
• a boom unit;
• a tool coupled to an end of the boom unit;
• a turntable unit fixedly mounted to the chassis on the longitudinal axis adjacent and separate from the cabin and spaced along the longitudinal axis from said front and rear wheels, the turntable unit coupled to and supporting the boom unit for rotation;
• a dump body mounted to a rear portion of the chassis, the dump body having a floor portion and faces for containing the load;
• a power plant mounted in the chassis;
• and
• at least one control unit coupled to supply motive power generated by the power plant to at least the turntable unit based on the operator's control action, the turntable unit rotating the boom unit to move over a second side of the chassis opposite the first side under control of the control unit so that the boom unit and coupled tool with the load can be moved between a first position in which the tool and the load are positioned forward of the chassis and a second position in which the tool and the load are positioned over the dump body.

A vehicle controlled by an operator, the vehicle capable of moving and carrying a load, the vehicle comprising:

• a chassis having a longitudinal axis symmetrically dividing the chassis through its middle;
• a cabin fixedly mounted on a first side of the longitudinal axis of the chassis on a forward portion thereof, the operator positioned in the cabin if operating the vehicle;
• a plurality of wheels coupled to the chassis, including front and rear wheels, to movably support the chassis;
• a steering unit having a wheel positioned in the cabin and coupled to at least two wheels, the steering unit operable by the operator to control the direction of movement of the vehicle;
• a boom unit;
• a tool coupled to an end of the boom unit;
• a turntable unit fixedly mounted to the chassis on the longitudinal axis adjacent and separate from the cabin and spaced along the longitudinal axis from the front and rear wheels, and coupled to the boom unit, the turntable unit supporting the boom unit for rotation;
• a dump body mounted to a rear portion of the chassis, the dump body having a floor portion and faces for containing the load;
• a power plant mounted in the chassis;
• hydraulic fluid;
• a hydraulic pump coupled to the power plant and generating a supply of pressurized hydraulic fluid;
• a valve control block unit coupled between the hydraulic pump and the turntable and boom units, the valve control block unit receiving pressurized hydraulic fluid from the pump;
• and
• a control unit generating at least one control signal based on control action of the operator, the control unit coupled to supply the control signal to the valve control block unit, the valve control block unit controlling at least one flow of pressurized hydraulic fluid to the turntable unit and the boom unit, based on the control signal, the control unit capable of controlling the flow of pressurized hydraulic fluid to the turntable unit to cause the boom unit and coupled tool with the load to move over a second side of the chassis opposite the first side so that the tool can be moved between a first position in which the tool is positioned forward of the chassis to pick up the load and a second position in which the tool is positioned over the dump body to dump the load into the dump body.
