A device for the relief of at least one power lift of a commercial vehicle

摘要

The working attachments of the utility vehicle are controlled hydraulically to raise and lower and to adopt a neutral setting. Additional control valves (18,19) provide a reduced pressure level to enable the attachments to be lifted out of the operating position e.g. to turn the vehicle into a new working position. No separate fluid reservoir is required. The hydraulics operate with priority, e.g. for braking and steering. Pressure is reduced by the additional valves and by dumping valves (15,16,17) all solenoid controlled. USE/ADVANTAGE - No separate pressure reservoir required, improved handling control, e.g. for working depth of agricultural machine.
