Abstract
An improved material pusher or containment plow employing a floating vehicle-coupling system, a modular composite scraping edge, a front-pivoting wear shoe with an adjustable angle, as well as water-shedding features. The disclosed containment plow and features are provide improved the surface outcome under various snow and ice conditions.
Claims5
A containment plow for clearing material from a surface, comprising:
- an upstanding transverse blade with a front surface and a rear surface, said rear surface of said blade being reinforced by at least one longitudinal channel extending substantially the length of the plow and in parallel with said blade;
- a vertical side plate attached to and extending at least forward from each vertical edge at the ends of said transverse blade;
- a coupler by which the containment plow may be attached to a vehicle;
- a plurality of removable scraping edge sections, positioned adjacent one another along a bottom edge of said blade, at least one of said scraping edge sections presenting a plurality of faces for contact with the surface;
- and
- a pair of adjustable wear shoes freely pivotally attached to a respective one of the vertical side plates with a pivot pin adjacent a front edge of each thereof.
