What is the most common sizing mistake when choosing a vibratory pile driver?

Question

VANROCK Group · Accepted Answer

The main sizing mistake is choosing by hammer size alone instead of matching both the excavator class and the hydraulic oil flow. Each model has a defined carrier range and a defined flow window.

- VR-SH 25: 20–26 Tons, 150–170 LPM
- VR-SH 30: 28–36 Tons, 180–220 LPM
- VR-SH 40: 36–50 Tons, 240–260 LPM

A second mistake is overlooking total installed mass. The published figures separate hammer weight from extension boom weight, so both need to be considered in the attachment set-up. For example, VR-SH 40 is 2,050 kg hammer weight plus 700 kg extension boom weight. The correct choice is the model that fits the excavator class and can be supplied with the required 300 bar and oil flow.
