Hydraulic Auger Unit with 2000-15000 ft-lbs Torque and 20-60 RPM Variable Speed for 6-36 Inch Diameter Bits

An excavator-converted auger drill repurposes the excavator's existing hydraulic system to power an attached auger drive unit (mounted on the excavator's arm). The excavator's hydraulic pump supplies pressure and flow to the drive unit, which uses a gear-reduction mechanism to convert hydraulic energy into high rotational torque — driving the auger bit to penetrate soil, rock, or other ground materials. The excavator's arm controls the drill's vertical positioning and depth, while the drive unit regulates speed/torque for stable, precise drilling.

• Solar PV Pile Installation: Drilling foundation holes for solar panel support piles (the top application for renewable energy construction).
• Foundation Construction: Boring holes for building footings, utility poles, or retaining wall anchors.
• Landscaping & Fencing: Installing fence posts, tree planting holes, or landscape edging anchors.
• Geotechnical Sampling: Collecting soil samples for site surveys (paired with specialized auger bits).
• Agricultural Applications: Drilling holes for crop irrigation systems or farm equipment anchors.

• Cost Efficiency: Eliminates the need to purchase a dedicated auger rig — leverages existing excavator assets.
• Versatility: The excavator's articulated arm enables access to tight spaces (e.g., sloped terrain or crowded job sites) that dedicated rigs cannot reach.
• High Productivity: The excavator's powerful hydraulic system delivers higher torque than small skid-steer augers, reducing drilling time for deep solar piles (3-10 ft depth).
• Easy Operation: Uses the excavator's existing controls (minimal training required for operators familiar with excavators).

Our excavator-converted auger drill system (compatible with 5-20 ton excavators) integrates a heavy-duty auger drive unit, customizable auger bits, and universal mounting brackets. It delivers 2,000-15,000 ft-lbs of torque, 20-60 RPM variable speed, and supports 6-36 inch diameter bits — optimized for solar PV pile drilling and large-scale foundation projects. We offer bulk/OEM supply with 500+ units/month capacity.
