RETRACTABLE SNOW PLOW WING ASSEMBLY

摘要

A side wing plow assembly for use on a vehicle comprises an elongated blade, an articulated forward connector assembly for connecting the inner end of the blade to the vehicle and a rear connector assembly for connecting the outer end of the blade to the vehicle rearwardly of the vehicle cab. The forward connection assembly includes a generally vertical inner plate member for attachment to the vehicle frame and a generally vertical outer plate member laterally spaced from the inner vertical plate. A transverse plate member pivotally connects to lower regions of the inner and outer plate members. An upper hydraulic cylinder connects between upper regions of the inner and outer plate members and a lower hydraulic cylinder connects between the inner plate member and an outer region of the transverse plate member. The upper cylinder is adapted to tilt the outer plate member and blade and the lower cylinder is adapted to raise and lower the outer plate member and blade. A blade support plate is hinged to the outer plate member by means of a vertical hinge, with the blade being connected to the support plate by means of a horizontal pivot pin allowing the blade to swing up and down relative to the support plate. The rear connector assembly includes a telescopic arm pivotally connectable at its inner end to the vehicle and pivotally connected at its outer end to the outer end of the blade, the arm including a hydraulic cylinder for extending and retracting the telescopic arm. A further hydraulic cylinder is pivotally connected between the vehicle and an upwardly extending bracket on the telescopic arm, this further hydraulic cylinder being adapted to raise and lower the outer end of the blade.
