The Heaviest-Duty Crane Pump We Cover
The A4VSO250 is a large-displacement variable/load-sensing pump specified for the heaviest crawler crane applications — the same Liebherr LR, Manitowoc, and Kobelco CK family that uses the A11VO130, but at a significantly larger displacement class for the biggest lift-capacity machines.
At 250 cc/rev and 400 bar, this is among the largest and highest-value pumps we handle — reserved for the biggest crawler cranes in heavy lift and infrastructure work. Given the scale and safety stakes involved, we're especially thorough with documentation on this specific model — the written test report becomes essential supporting evidence for your crane's own safety compliance records.
| Machine | Type | Pressure | Displacement |
|---|---|---|---|
| Liebherr LR series (heavy) | Crawler Crane (heavy lift) | 400 bar | 250 cc/rev |
| Manitowoc heavy crawler cranes | Crawler Crane (heavy lift) | 400 bar | 250 cc/rev |
| Kobelco CK series (large) | Crawler Crane (heavy lift) | 400 bar | 250 cc/rev |
