The device includes two opposing lateral wings forming the right and left sides of the scraping device. Each wing includes an upper section through which the wing is attached to the central support about a vertical pivot axis, and a bottom section that is pivotable with respect to the upper section about a first horizontal pivot axis. Each wing can follow the unevenness of the roadway surface and may also include parts that can pivot backwards in case of a frontal impact with an obstacle. The scraping device offers a very high degree of versatility and can clean various kinds of roadway surfaces with an unprecedented level of efficiency.

A multi-position snowplow blade, a snowplow incorporating the blade and a method of use thereof. The blade includes left and right wings that each having a trip edge pivotally engaged therewith. Each trip edge includes a lower section of a moldboard, a cutting edge, and a snow shield. A biasing assembly biases the trip edge into alignment with an upper section of the moldboard. The trip edges trip when the blade strikes an obstacle on a surface being plowed. When the trip edge trips, it pivots about a horizontal axis and relative to the associated upper section. Each snow shield pivotally engages the lower section of the associated trip edge and pivots relative thereto when the trip edge trips. The pivotal motion of the two snow shields widens a gap therebetween and helps to reduce the possibility of damage to the pivoting trip edges.

A V-blade for a snowplow, a snowplow incorporating the V-blade and a method of use thereof. The blade includes left and right wings engaged with a central shaft. A trip edge is provided on each wing and includes a lower section of moldboard, a cutting edge, and snow shield engaged with an upper section of the moldboard via a biasing assembly. The assembly biases the trip edge into alignment with the upper section. When an obstacle on the surface is struck by the trip edge, the trip edge pivots relative to the upper section about a horizontal axis extending along a shaft of the biasing assembly. A translation assembly causes the trip edge to move laterally in a first direction away from the central shaft and parallel to the vertical axis extending therealong. The trip edge returns to its original position under spring force.

A vehicle mounted articulating snow plow apparatus is provided for clearing snow from roads and driveways. The snow plow includes a blade assembly having a center blade and an extendable wing blade coupled to each end of the center blade. The blade assembly can be raised and lowered relative to the vehicle and ground surface and can be rotated about a vertical axis. Each extendable blade is independently pivotable relative to the center blade through an arc of greater than one-hundred eighty degrees (180°) about a vertical axis. The blade assembly is extendable and retractable between at least a stowed configuration, wherein the extendable blades extend laterally inboard alongside the center blade, and a linearly extended configuration, wherein the extendable blades are outboard of the center blade. The blade assembly includes an actuation mechanism to pivot the extendable blade relative to the center blade.

An adapter assembly includes upper and lower crossbars that are horizontally oriented and spaced vertically apart from each other, with each of the upper and lower crossbars having oppositely-disposed outboard ends. A pair of L-shaped brackets and a spacer bracket are mounted adjacent each outboard end of each of the upper and lower crossbars and horizontally orient and space the upper and lower crossbars vertically apart from each other. The pair of L-shaped brackets having lower legs configured to couple with the mount attached to the frame of the vehicle. The adapter assembly is adapted to couple with existing mounts installed on passenger vehicles, such as mounts adapted for the attachment of snow plows, to permit the attachment of a wide variety of implements and accessories to the front ends of such vehicles.

A system of actively introducing opposite phase vibrations to reduce or cancel vibrations caused by operating a snow plow and a method of actively introducing such opposite phase vibrations.

A snowbank deconstructing system includes a dulled motorized instrument configured to make repetitive, low-impact contact with accumulated snow. The dulled motorized instrument is configured to be safe to human touch during the repetitive, low-impact contact with the accumulated snow.

An autonomous snowbank deconstructing system includes an autonomous vehicle, one or more boom arms coupled to the autonomous vehicle, and a dulled shovel component coupled to the one or more boom arms. The autonomous vehicle is configured to autonomously gather loose debris to form one or more debris piles with repetitive, low-impact contact of the dulled shovel component with the loose debris, and autonomously deconstruct accumulated debris with repetitive, low-impact contact of the dulled shovel component with the accumulated debris.

A containment plow adapted to be mounted to a vehicle such as a skid steer, a wheeled loader, or a tractor comprises a moldboard frame, a moldboard mounted to the moldboard frame, a wing pivotally connected to the moldboard frame adjacent each end of the moldboard, a moldboard cutting edge mounted to a lower edge of the moldboard and comprising a plurality of cutting edge segments, and a wing cutting edge mounted to a lower edge of each wing. Each moldboard cutting edge segment is mounted so as to have two rotational degrees of freedom movement relative to the moldboard and one translational degree of freedom movement relative to the moldboard. Each wing cutting edge is mounted so as to have two rotational degrees of freedom movement relative to the wing.

A snow plow-blower operates as a snow plow, snow blower/thrower or as a snow plow-blower combination. The snow plow-blower includes a plow head blade and at least one blower door. The cavity contains a snow moving means, single, dual, or multi staged, for moving snow, ice and other materials out through at least one discharge chute and/or at least one opening. The blower door is adapted to move to an open configuration to expose said cavity, and from the open configuration to a closed configuration to thereby prevent snow, ice and other material ingress into the snow blower unit. Preferably, at least one retractable and extendable wing is located on the plow head blade to advantageously provide varying closed and open extended position configurations or positions for the removal of snow, ice or other material and debris.
