Grader blade stabilization system
Automation in Construction 7 (5) (1998) pp. 385-389
Graders are used for ground grading or levelling. The desired profile is achieved by passing the machine over the ground surface with appropriately positioned grader blade. Grading errors are caused mainly by vertical displacements of grader front wheels. These displacements, despite a considerable wheel base of the grader, are transferred through the frame onto the grade blade. Moreover the quality of surface levelling is also influenced by the compliancies of the ground, the chassis and the blade suspension system. In the paper a blade stabilization system is proposed. The blade adjustment system with hydraulically driven mechanism is controlled using position signals from the selected points of the machine.
