Tilt control

摘要

A motor vehicle equipped with lift arms and a bucket for handling material. The vehicle has a fluid power system including piston and cylinder assemblies to pivot the lift arms between down and up positions and tilt the bucket relative to the lift arms. A bucket leveling control apparatus operates a fluid control valve in response to the pivotal movement of the lift arms to control the flow of fluid to the bucket tilting piston and cylinder assembly to maintain the bucket substantially level during the movement thereof between down and up positions. The fluid control valve is operable to supply fluid under pressure to the bucket tilt piston and cylinder assembly to move the bucket to a dump position.
