SNOWPLOW ASSEMBLY |
摘要 |
A snowplow assembly comprises a lift frame and A-frame operably pivotally connected together and an actuator operably connected between the lift frame and A-frame for effecting relative pivotal movement befweert the lift frame and A-frame. A plow blade includes a blade frame. The blade frame includes a tube of circular cross section which is operab ly pivotally connected to the A-frame. The tube is pivotally received by a quadrant, which is operably connected to the A-frame. A resilient element is operable between the blade frame and A-frame normally biasing a lower edge of the plow blade forwardly. The resilient element is an elastomeric loop. T he pivotal connection of the plow blade to the A-frame in combination with the resilient element provides a trip function of the plow blade. The plow blade is a composite. The circular tube of the blade frame provides torsional stiffne ss to the composite blade.
