One Step Below the A4VG71 — Small & Tower Crane Duty
The A4VG56 fills the gap just below the A4VG71 in Rexroth's closed-circuit family, commonly specified for small mobile cranes and tower crane applications where slightly lower displacement matches the equipment's travel/auxiliary drive requirements.
Tower cranes and smaller mobile cranes generally need less travel-drive displacement than the large crawler cranes that typically specify A4VG180 or larger units (see our crane pump range) — the A4VG56 matches this lighter-duty segment while still running the full 400 bar pressure rating common across Rexroth's crane-application A4VG variants.
| Machine | Type | Pressure | Displacement |
|---|---|---|---|
| Small mobile cranes | Crane (travel/auxiliary drive) | 400 bar | 56 cc/rev |
| Tower cranes | Crane (travel/auxiliary drive) | 400 bar | 56 cc/rev |
