SNOW PLOW ROTATING SIDEWALL WITH SUSPENSION

摘要

A snow plow blade assembly has sidewalls rotating when abutting an obstacle and returning to the default position when not abutting the obstacle anymore. The snow plow blade assembly comprises a central section comprising a pivot axis; sidewall assemblies pivotably mounted to the central section; and suspension assemblies mounted to the central section. The suspension assemblies connect the central section and the sidewall assembly distant from the pivot axis. The suspension assemblies may comprise a hydraulic jack controllable between an extended position and a compact position, wherein the suspension assemblies allows the sidewall assemblies to pivot up to a first angle when contacting an obstacle and to pivot to a second angle greater than the first angle by changing the position of the hydraulic jack.
