WING PLOW POST

摘要

A wing plow post and method of manufacturing the post is disclosed. The post is intended for attaching a wing plow to vehicle for moving material, such as snow. The links of the post are parallel to the angle of the wing plow when the plow is in the plowing position to minimize stress on the post and frame of the vehicle. The post includes a float collar on the hydraulic lift cylinder to provide free floating of the toe end of the wing plow. It allows a wing plow to move over road surfaces and limit the stress on both the post itself and the frame of the vehicle to which the post is attached. Further, the present invention also allows power to be provided by a hydraulic cylinder in the downward direction to the toe end of the wing plow.
