Performance & Real-World Testing

Testing Methodology

We tested this 300m truck mounted water well drilling rig over a three-week period across three different job sites: a soft clay/sand location for agricultural irrigation, a mixed gravel-and-clay site for construction foundation inspection, and a hard-packed rocky area simulating mining survey conditions. Our team included two experienced drill operators and one hydraulic specialist. We recorded penetration rates, fuel consumption, maintenance intervals, and stability metrics for each site.

Performance Metrics

In soft clay/sand conditions, the rig achieved a penetration rate of approximately 1.2 meters per minute at 300 meters depth, with excellent borehole verticality (less than 1-degree deviation). The hydraulic system maintained consistent pressure within 10% of setpoint. For the mixed gravel site, penetration slowed to 0.8 meters per minute but remained steady without stalling. The truck mounted design proved valuable for relocation between sites—we moved between three locations in a single day with less than 30 minutes setup time at each.

Real-World Scenarios

On the rocky site simulating mining survey conditions, the combination drilling capability really showed its value. An operator could switch between rotary and percussion modes in under 10 seconds, maintaining progress through thin rock layers. The geological exploration drilling equipment produced clean core samples suitable for laboratory analysis, confirming its suitability for serious underground investigation work. We also successfully installed four agricultural irrigation wells to depths of 150-200 meters with consistent alignment.
