FOLDING BLADE

摘要

A mid-chassis, underbody plow or scrapper blade is mounted under a vehicle chassis to be folded upwardly for storage when not in use. The blade is also mounted to permit the outer ends of the blade to move vertically. Pneumatic pressure actuators mounted on either side of the center line of the vehicle apply pressure through blade support means in the form of pivot arms to the respective ends of the blade to control the scrapping action. The blade support means swings upwardly to achieve a two-stage storage which increases the elevation of the blade when folded.
