US Patent 7264296 Feed truck compartment lid control system

A feed truck compartment lid control system. The system includes coupled feed compartment lids on an upper surface of a feed truck trailer and includes cylinders in proximity of the lids such that the cylinders require much less force and power, and thus much less air pressure, to open and close the lids. The cylinder arms are connected directly to elongated bars that couple a plurality of feed compartment lids to one another. At least one of the lids includes wheels to allow the lids to travel across the upper surface of the feed truck trailer as they are opened and closed.
