摘要: A level and slope control for road graders and similar surfacing machines is described in which one or more very narrow electromagnetic beams are projected along the path to be graded, and photoelectric sensors on the grading machine are utilized to receive and detect positional information from the light beams and to generate correction signals which both adjust the position of the surfacing blade and steer the machine in the desired direction.
