Choose the model by excavator size first, then confirm hydraulic flow. the pile decides the clamp, the excavator decides the model.

- VR-SG 15: 14–22 ton excavators
- VR-SG 25: 20–26 ton excavators
- VR-SG 30: 28–36 ton excavators
- VR-SG 40: 36–50 ton excavators

After that, check the oil flow and force level. Centrifugal force rises from 313 kN on VR-SG 15 to 940 kN on VR-SG 40. All four have 360° rotation, ±30° tilt, 65 mm bottom jaw opening, and a pile grip range of Ø76–610 mm. Only the side clamp opening differs on VR-SG 15, at 288 mm instead of 312 mm.
