Civil engineering road levelling scraper assembly has height-adjustable scraper blade that also tilts in response to vehicle motion

摘要

An irregular road surface under construction is reduced to a flat condition by a scraper blade (10) straddled between two rails. The scraper blade hangs from a first frame (12) that is located and height-adjustable within a second frame (16). The pitch angle of blade presentation to the road surface is also adjustable.
