  • Patent number: 5630689
    Abstract: A bale transport comprising a carrier frame including a pair of elongated spaced beams and a pair of elongated rails secured to the beams and spaced inwardly therefrom in general parallel relation thereto. Wheels are secured to the carrier frame, and hydraulic cylinders connect the carrier frame and the wheels for raising and lowering the frame with respect to the ground surface. A loading frame is on the carrier frame and a power mechanism on the carrier frame rigidly extends the loading frame laterally with respect to the carrier frame in order to load a bale onto the elongated movable height adjustable carrier frame. In operation, the loading frame is slid laterally by the power mechanism to a laterally extended position with respect the carrier frame. The carrier frame is moved longitudinally so that the loading frame is on an engagable position with a bale to be loaded resting on a supporting surface. The carrier frame is lowered to substantially the same level as the surface supporting the bale.

  • Patent number: 5236294
    Abstract: A hay bale transport has a frame consisting of a plurality of spaced inverted U-shaped frame members which are secured together in spaced parallel relation by elongated beams extending along the lower ends thereof. An elongated longitudinal alley space exists within the frame for receiving a plurality of bales to be transported. Spaced elongated bale supporting rails extend within the frame and are secured to the beams. Wheels are secured to the frame and are connected to a power unit for raising or lowering the frame with respect to a ground surface whereby bales within the alley can be raised or lowered with respect to the ground surface. An operating cab is movably secured to one of the inverted U-shaped frame members and is normally positioned within the alley, but is connected to another power unit so that the cab can be laterally moved out of the alley while the bales are being picked up, transported, and discharged.
