What oil flow and pressure does each demolition shear model need?

Question

VANROCK Group · Accepted Answer

The hydraulic requirement depends on the model. For the main shear circuit:

- VR-DS 15: 250 bar and 200–250 LPM
- VR-DS 20: 320 bar and 200–250 LPM
- VR-DS 30: 320 bar and 250–320 LPM
- Rotation motor on every model: 160 bar and 36–40 LPM

All three models have 360° hydraulic rotation. VANROCK specifies a built-in speed valve, with speed-type total cycle times of 3 s on VR-DS 15, 5 s on VR-DS 20 and 7 s on VR-DS 30. If you are checking machine compatibility, match both the main circuit and the separate rotation requirement, not just carrier tonnage.
