| 摘要 |
The invention relates to a system for controlling at least one hydraulic cylinder (2, 3) comprising a first control valve unit (4), which is connected to said hydraulic cylinder for regulation of the latter, and a first operable control means (5) which is adapted for controlling the first control valve unit. The system also comprises a second control valve unit (6), which is also connected to said hydraulic cylinder for regulation of the latter, and a second operable control means (7) which is adapted for controlling the second control valve unit. The system also comprises means (23) for prioritizing the first control means. The prioritizing means (23) is controlled via hydraulics in such a way that the effect of the second control means (6) on the regulation of the hydraulic cylinder (2, 3) is at least substantially reduced as soon as the first control means (5) is operated. |
