Snow removal apparatus and method
12385202 · 2025-08-12 ·

A snow removal apparatus and related method for removing snow from an underlying surface. The apparatus includes a plow blade arranged to stand off from the underlying surface when the apparatus is in use, a first air transport unit for delivering forced air into an air blade plenum and a second air transport unit for delivering forced air to a Venturi vacuum jet. The air blade plenum is arranged to deliver air to the underlying surface to lift snow located thereon. The Venturi vacuum jet is arranged to push air and lifted snow into and through a collection chute. Use of the apparatus results in a cleaner roadway that results per pass at a higher speed with less need for the use of salt and/or sand and substantially less wear and tear on the roadway.

Snow wing assembly having independent rotational controls

In some implementations, a lift assembly for a moldboard of a snow wing assembly of a machine may include a lifting mechanism, coupled to an undercarriage assembly of the machine, configured to lift the moldboard of the snow wing assembly to a bench height associated with the moldboard. The lift assembly may include a hinge rotatably mounted on a bar of the lifting mechanism, wherein the bar defines a first axis, and wherein the hinge is rotatably coupled to the moldboard about a second axis. The lift assembly may include a first rotational mechanism, coupled to the lifting mechanism and the hinge, configured to rotate the hinge and the moldboard about the first axis. The lift assembly may include a second rotational mechanism, coupled to the hinge and the moldboard, configured to rotate the moldboard about the second axis.
