  • Patent number: 8732990
    Abstract: The wing lock is a safety mechanism for a snow plow blade and is engaged when the plow blade is not in use. The safety mechanism is primarily a pin and tongue assembly which is actuated by an air, electric, or hydraulic cylinder tied to the truck on which the plow is mounted. The pin is protected by a collar and sleeve which are disposed below the actuator cylinder. The tongue is affixed on the support arm of the plow wing so that when the support arm is raised the tongue slides into a receiving position for the pin. The pin drops through the tongue to lock the blade. For use, the safety mechanism is activated or deactivated from the truck cabin by a lighted, electrical switch which sends a signal to the actuator to deploy or retract the pin so that the plow may be locked or unlocked.

  • Patent number: 7493710
    Abstract: The left and right sideblades are hinged to the mainblade about vertical axes, and can pivot each through 180°. The sideblades are rotated by means of left and right hydraulic rotary actuators. The actuator includes a piston formed with helical splines, which drive a rotor sleeve of the actuator to rotate in a single-plane-circle when the piston is driven axially. The journal bearings in the rotary actuator are supplemented by bearings provided in a coaxial lower hinge, which are of much greater journal capacity than the bearings in the rotary actuators. The lower hinge protects the hydraulic rotary actuator from shocks due to the sideblade impacting against a kerb.

  • Publication number: 20070169384
    Abstract: A snow pusher attachment for use in conjunction with a straight blade angle-type snow plow mounted to a work vehicle. This pusher allows a work vehicle to capture, contain, and relocate large amounts of snow very quickly and efficiently. The attachment consists of side panels, connected by horizontal members between. This pusher attachment is secured to the snow plow by bracket assemblies, attached to the upper edge of the snow plow that engage hooks on the upper, rear portion of the pusher attachment. The attachment does not require the operator to exit the work vehicle to secure or release it from the snowplow. Accordingly, the attachment allows the quick and repeated conversion of a snow plow into a snow pusher box and visa versa.
