HYDRAULIC DRIVE OF SINGLE-BUCKET EXCAVATOR-LOADER |
| 摘要 |
FIELD: earth-moving machinery and equipment. SUBSTANCE: hydraulic drive of single-bucket excavator-loader is arranged with simultaneous connection of single-flow and double-flow bores in control spool valves of loader and excavator working attachment. This arrangement gives stable combination of any working motions at optimal distribution of hydraulic fluid. Excavating operations can be performed at combined output of two hydraulic pumps. This also allows for use of higher capacity hydraulic pump in operation with loader working attachment and improved transmission. EFFECT: higher capacity. 1 cl, 1 dwgr
