RETRACTABLE SNOWPLOW WING AND MOUNTING THEREFOR

摘要

RETRACTABLE SNOWPLOW WING AND MOUNTING THEREFOR A retractable snowplow wing and mounting therefor which can be installed on substantially any truck with a longitudinal frame. The wing which may basically be of any desired construction is supported at both its inboard and outboard ends to permit raising it and swinging it horizontally from plowing position to a position substantially parallel to the truck body. The mechanism comprises first means attached to the inboard end of the wing and slidably mounted for vertical movement on support means carried by the truck frame and second means attached to the outboard end of the wing and comprising an extensible strut and motor means both of which are pivotally mounted on a bracket secured to the truck frame and extending laterally therefrom. Said first means comprises a hanger mounted for horizontal pivotal movement on a vertically movable slide carried on said support means; and said motor means, which comprises a hydraulic cylinder, is slidably connected at its outer end with said strut and is pivotally mounted at its other end on said bracket whereby to raise and retract the outboard end of said wing. Said bracket is rigidly secured, as by welding, to said truck frame and depends therefrom with a member laterally removed from said frame supporting said strut and motor means. The wing is pivotally carried on said hanger to permit limited horizontal pivoting movement thereof against the resistance of a spring to allow the blade of said wing to pass over minor obstructions or irregularities in the pavement; and detent means is provided to selectively prevent such pivoting movement. A wing, according to the invention, can be mounted on either side of a truck or wings can be mounted on both sides.
