Abstract
A method for handling large cylindrical bales includes loading a first group of bales on an elongated trailer, elevating the bales, loading a second group of bales on the trailer, and lowering the first group of bales onto the second group for stable transportation of a relatively large number of bales. An apparatus for carrying out such a method includes the trailer having a conveyor extending therealong, a loader device on the trailer for engaging bales on the ground and depositing the same on the conveyor, bale supporting platform sections extending along the conveyor, drive shafts with sprockets thereon rotatably supported on the trailer and extending along the top side of the trailer, drive chains connected to the platform section and engaging the sprockets, and a motor operatively connected to shafts to rotate same and thereby effect elevation of the bales supported by the platform sections.
