  • Patent number: 8887413
    Abstract: A material box can telescope between larger and smaller widths to accommodate legal requirements of traveling down the road, making traveling between job sites easier and safer than conventional, unadjustable material boxes. The material box can be used in a wide configuration to plow a wider area, such as empty parking lots, cutting down work time. When cars are present, the material box can be made narrow to accommodate for the vehicles while still being an effective material moving device.

  • Patent number: 7596892
    Abstract: A blade (3) meant to work in the curved form of a snow plough and attached from its lower edge to a rigid beam, the upper edge of which is supported by means of upper beam (12) or similar, and said blade is of flexible material, as plastic sheet. The blade is from its upper beam (12), essentially from its middle, supported by suspension means (9), which due to the ploughing load allows upper beam (12) and blade (3) upper edge to tilt and blade (3) to change the radius of curvature at least from the suspension spot on the blade area toward the blade point.

  • Patent number: 7523569
    Abstract: A mounting for a side wing plough includes a mounting having two relatively movable sectorially formed elements, one of which being fixed to the plough and the other being connected to a lifting means for the leading end of the plough. The two elements register with one another and are guided thereby, the interengagement of the elements constituting the connection enabling movement of the plough and also permitting limited compensatory shifting of the plough upon encountering an immovable obstacle. The mounting could further include a tilt mechanism of limited stroke affording the capability of the plough to tilt toward the vehicle to accommodate unpredictable movement of the plough upon impacting an immovable obstacle.

  • Patent number: 5638618
    Abstract: A plow assembly is disclosed for vehicles such as pickup trucks and tractors for moving snow or other materials. The plow assembly has at least one extendable, forwardly pivotable plow wing which is extendable on one end of a main plow by sliding movement along the front of the plow between a retracted and an extended position in which the plow wing is generally aligned with the plow front surface. The plow wing is also pivotally mounted on a hinge for movement between the extended position and a forwardly angled position in which the plow wing front surface extends at an angle to the plow front surface. A power source connected to the plow wing is operable to move the wing between the retracted, extended and forwardly angled positions. Preferably, a latch assembly prevents pivotal movement of the plow wing to the forwardly angled position until the plow wing is in the extended position.

  • Patent number: 5509219
    Abstract: A Light Weight Portable Snow Plow for a vehicle having a bumper. The single piece blade is mounted on top of two tubular U-hooks. Each U-hook is inserted into molded pockets on the back of the blade. The U-hooks, in turn, are attached through hubs to a lower tubular U-support. The lower U-support extends downward and rests on the vehicle bumper. An upper U-support is also attached to the hubs. The upper support extends over and rests on the vehicle hood or trunk lid. Support straps are also attached to the hubs. At the distal end of the support straps are hooks to attach the straps to the vehicle wheel well and in turn the tubular supports and the blade to the front or rear of the vehicle. The vehicle bumper engages the rear of the bottom U-support to push the supports and thus the blade. The width of the U-hooks are different causing the blade to sit at an angle to the vehicle. The angle of the blade forces snow to one side as the vehicle moves.

    Abstract: A method and apparatus for removing snow from roadways and the like includes the provision of a curved scraper blade having top and bottom edges and defining a generally circular passageway forward of the blade extending longitudinally the length of the blade. Forward movement of the blade causes the bottom edge to lift up snow from the roadway and as it is urged into the passageway, pressurized air from an air blower is expelled into the passageway, causing the snow therein to be expelled laterally of the scraper blade and over the roadside. The pressurized air may be expelled into the passageway through one or more apertures in the blade intermediate its ends or alternatively, through an aperture at either end of the blade.

  • Patent number: 4821436
    Abstract: A high-performance plow system to be attached to a pickup truck or similar vehicle. The plow blade can be angled across the plowing surface and with respect to the motion of the vehicle up to about 45.degree., it can roll to allow the blade to track changing pitch angles along the plowing surface contours. The blade has two protective mechanisms, the first one being an appropriately-designed rake angle scraper structure, disposed at the bottom edge of the plow blade, the second one being a mechanism which attaches the blade to an A-frame assembly (AFA) by pitch and shear pins. The shear pins break if too tall an object is hit and allow the blade to fall over the object. The pins allow 30 second removal/attachment of blade.
