Continuous auger YG series

hydraulicfor excavatorspiling

Product overview
Mounting a high-torque excavator auger boosts hole drilling speed by over five times compared to manual work. A hydraulic auger drive uses a planetary gearbox to turn auger bits with high output torque, drilling clean straight holes within minutes. Mechanical drilling lowers labor bills and keeps operators out of hazardous work zones.

Where contractors deploy an excavator auger

• Solar farms and utility piling: drills straight foundation holes rapidly across varied ground conditions.
• Fencing and tree planting: fast, clean post holes for roadsides and farm lines.
• Building foundations and retaining walls: precise deep holes in dense soil for poles and footings.
• Site clearance and teamwork: augers handle foundation drilling quickly and can be paired with compactors, magnets and slurry pumps to support backfill and cleanup operations.

Operator tips

• Use tungsten bullet teeth when drilling shale or soft rock; standard flat teeth wear rapidly in rock.
• Lift the auger bit every half meter in heavy clay to clear packed dirt; full flighting can bog down the pump and jam the motor.
• Check planetary gearbox oil levels weekly; heavy drilling generates heat and low oil can damage gear sets.

Case study — Solar project in Australia (summary)

• Jobsite challenge: hard shale and dry clay limited drilling output to ~20 post holes/day and caused fast bit wear.
• Equipment solution: pairing a high-torque auger drive (model with up to 4890 Nm torque, 65Rd shaft) with a rock bit fitted with tungsten bullet teeth for the compact digger.
• Results: drilling speed increased ~400%, single-hole time dropped below 3 minutes, daily output rose to over 90 holes and the crew finished the job significantly ahead of schedule.

Frequently asked selection notes

• Output torque is the primary factor for hard soils, shale or rock; higher rpm is more effective in soft soils to eject cuttings quickly.
• Choose standard flat teeth for dirt, sand and soft clay; choose tungsten bullet rock teeth for hard clay, sandstone, weathered rock and asphalt.
• Shaft extensions can be added between the 65Rd output shaft and auger bit using quick pin locks; anti-sway drive setups improve deep-hole accuracy.
