A snow plow apparatus including at least one pivotable plow wing that is capable of removing snow or debris adjacent to a vehicle. The pivotable plow wing is operable to deploy from a stowed configuration behind the vehicle to a deployed configuration where the plow wing substantially extends beyond a side of the vehicle and is in contact with a surface to be plowed to remove snow adjacent to the footprint of the vehicle. Once deployed, the pivotable wing is configurable to direct snow or debris away from or toward the vehicle by adjusting the angle of the plow wing relative to the direction of travel of the vehicle. The snow plow apparatus includes powered actuators and an electronic control unit that coordinate to operate the snow plow apparatus without the need for an operator to manually deploy, stow, or position the snow plow apparatus.

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.

The present disclosure is directed to systems and methods for operating a grading machine. The method includes (i) receiving information regarding material on a surface, and the grading machine is configured to travel on the surface and move the material on the surface; (ii) determining a set of parameters for operating the grading machine, and the set of parameters include an articulation angle of the grading machine and a moldboard angle of a moldboard of the grading machine; and (iii) positioning a snow wing and the moldboard of the grading machine based on the set of parameters such that the snow wing has a predetermined spatial relationship with the moldboard.

A snow plow having a wing that is rotatably coupled to a side of a primary plow, and configured to rotate about a first axis substantially parallel to the side of the primary plow. A portion of the wing is operable to rotate about a second axis that is non-parallel to the first axis, where the portion is operable to rotate upward about the second axis relative to the ground in response to the wing encountering an obstruction. A snow plow having a receiver coupled to a surface of the primary plow and an actuator coupled to the receiver. The receiver allows the snow plow to move proximally and distally with respect to a vehicle.

The laser light safety guide to assist in guiding a prime mover utilize for snowplowing including a laser that can be mounted within a cab of the prime mover and oriented to emit a visible laser beam directed through a transparent structure the prime mover. The laser light safety guide further comprises a shielding structure opaque to the visible laser beam that is trimmable or adjustable to enclose a space extending from a portion of the laser from which the visible laser beam is emitted to the transparent structure the prime mover. The shielding structure mitigates or contains reflection of the visible laser beam from an interior surface of the transparent structure.

The receiver allows the snow plow to move proximally and distally with respect to a vehicle.

A plow assembly includes a mounting structure configured to mount at a vehicle, a center plow attached at the mounting structure, and a plow wing mounted at an end of the center plow via a first attachment assembly and a second attachment assembly. Each of the first and second attachment assemblies includes an elongated attachment element and a biasing element. The elongated attachment element attaches a respective rear portion of the plow wing at the center plow and engages the biasing element at the rear of the center plow. The biasing element allows for movement of the attachment element at the rear of the center plow to allow for pivotal movement of the plow wing relative to the center plow. The biasing element limits pivotal movement of the plow wing and biases the plow wing towards a neutral state, where the plow wing is generally normal to the center plow.

A plow blade system adapted for mounting to a vehicle, the blade system comprising a blade orientable transversally to a longitudinal orientation of movement of the vehicle and having two opposite ends, and two side wall assemblies; each side wall assembly having a primary sidewall portion mounted to a corresponding end of the blade, the primary sidewall portion extending longitudinally from the corresponding end in a first longitudinal working direction, a sidewall extension slidably mounted to the primary sidewall portion, and a sidewall actuator mounted between the primary sidewall portion and the sidewall extension and operable to selectively slidingly extend the sidewall extension in a second longitudinal working direction opposite to said first longitudinal working direction and retract the sidewall extension within the primary sidewall portion.

The scraper blade device is provided for cleaning a roadway surface. The scraper blade device includes an upper blade portion and a bottom blade portion. The bottom blade portion has a plurality of widthwise-disposed and juxtaposed blade segments. The blade segments are provided in one or more blade segment sets where the blade segments within a same set are attached using a swivel interconnection. This scraper blade device has an improved cleaning efficiency over existing designs, thereby reducing the amount of de-icing chemicals and increasing road safety when used for removing ice and snow from the roadway surface.
