Snowplow blade lift mount assembly

摘要

A lift mount assembly is provided for a plow blade unit mounted on the front of a vehicle having longitudinally extending frame members and a laterally extending bumper at the front ends of the frame members. The assembly includes a supporting portion comprised of mounting plates attached to the front ends of the frame members behind the bumper, and laterally extending upper and lower tubular cross members between the mounting plates. The supporting portion further includes a pair of lift arm mounting members on the upper cross member extending to a point just above the bumper, and a bracket on the lower cross member providing a forwardly open socket just below the bumper. The lift mount assembly also includes a lift arm unit comprising a lift arm pivotally interconnected with the lift arm mounting members and extending forwardly over and closely adjacent the bumper, a lift cylinder support arm received in the socket and extending forwardly beneath and closely adjacent the bumper, and a generally vertically extending lift cylinder between the support arm and lift arm and closely adjacent the front of the vehicle bumper. The lift arm unit is adapted to be quickly removed from or attached to the supporting portion by means of quick hitch-type pin connections between the lift arm and lift arm mounting members and between the support arm and bracket.
