ABSTRACT:
A loading and transport vehicle, especially for a load like a cotton module, has an elongated, relatively high main frame supported on some ground-engaging wheels. An elongated conveyor frame carries a horizontal conveyor belt driven preferably at a surface speed coordinated with the rotational speed of a ground-engaging wheel. The conveyor frame is supported through vertically movable, hydraulically expansible chambers on the main frame and is guided for movement between a horizontal position on the ground and a higher horizontal position pressing a load on the conveyor belt against a ceiling on the main frame. The chambers may put force on the conveyor frame to lift the ground-engaging wheels, which can then be moved transversely to vary the tread between one position beneath the conveyor frame and another position alongside the conveyor frame.
