ABSTRACT:
A support arrangement for a blade of a construction machine is disclosed where the blade is located to one side of the construction machine. The support arrangement includes two support towers spaced in the length of the frame of the machine with these support towers accommodating variation in the elevation of the blade. The blade is pivotally secured at a forward end thereof to one of the support structures and secured adjacent the other end of the blade to the other support structure by means of two hydraulic cylinders which extend outwardly from the support structure. These hydraulic cylinders also include an arrangement for controlling the angle of the two hydraulic cylinders relative to the connected support structure. The arrangement for controlling the angle of the two hydraulic cylinders accommodates limited, rapid upward movement of the blade. This arrangement allows convenient adjustment of the blade to any desired operating position to one side of the construction machine while also providing an inherently strong support arrangement. This arrangement has particular application for snow wings normally secured to a motor grader or truck.
