Abstract (en)
[origin: EP0624690A2] The grader has a hopper (1) which is mounted on the tracked base truck (2) by means of a fifth wheel (3); the post (6) on which the operator climbs is absolutely independent, and the grader blade (5) is arranged below it; the entire assembly is connected to the truck supporting the hopper (1) by means of levers (4) that can move so as to form a parallelogram, thus allowing grading work to be performed in a fully automatic manner, with perfect working results and great economy in construction costs. <IMAGE>
