The HFP35000 Hydraulic Auger Drive is engineered for heavy excavators operating in the 20 to 45 tonne class, delivering exceptional torque output, controlled low-speed rotation, and long service life across the most demanding civil, mining, and infrastructure drilling applications.
Designed for major civil works, infrastructure projects, piling preparation, foundation drilling, utilities, mining support, and large-scale construction projects, the HFP35000 provides extreme ground penetration while maintaining hydraulic stability, precise control, and excellent reliability under continuous high-load operation.
Built for harsh Australian operating conditions, the HFP35000 features a premium Danfoss hydraulic motor paired with a heavy-duty epicyclic planetary gearbox, delivering up to 35,265 Nm of torque at 310 Bar pressure and supporting heavy auger diameters up to 1,500mm.
Backed by an industry-leading Lifetime Non-Dislodgement Shaft Guarantee and supported locally in Kilsyth with spare parts, technical advice, and direct workshop service.
Key Features & Benefits
- Integrated Non-Dislodgement Drive Shaft: Mechanical safety design guarantees the drive shaft will not dislodge or separate from the housing under extreme tensile extraction forces (pullout loads).
- Premium Danfoss Hydraulic Motor: Driven by genuine high-torque Danfoss hydraulic motor architecture for maximum power efficiency, high-pressure flow handling, and extended service life.
- Heavy-Duty Planetary Gearbox: High-pressure epicyclic reduction gearset delivers continuous torque multiplication up to 35,265 Nm across extreme ground conditions, hard rock, and shale.
- Comprehensive Australian Warranty: Backed by a Lifetime Shaft Guarantee, 3-Year Gearbox Warranty, and 2-Year Hydraulic Motor Warranty.
- Heavy-Duty Output Shaft: 110mm square output shaft engineered for maximum torque transfer and high-load drilling.
- High-Pressure Hydraulic Architecture: Rated to 310 Bar operating pressure for demanding heavy excavator auxiliary circuits.
- Supports Augers up to 1,500mm: Suits HFP A10 Series 110mm square drive augers ranging from 300mm to 1,500mm in diameter.
- Complete Hydraulic Package: Includes 1" high-pressure hydraulic hoses and adaptors ready for installation.
- Custom Configured: Custom ear and pin setup tailored to match your specific excavator hitch and pin geometry.
Industrial Drive System
The HFP35000 combines a premium Danfoss hydraulic motor with a heavy-duty epicyclic planetary gearbox to deliver efficient torque multiplication across extreme ground conditions.
Its integrated non-dislodgement mechanical safety shaft ensures that even during heavy tensile extraction (pulling large-diameter augers out of sticky clay, deep foundation holes, or piling sites), the drive shaft remains permanently locked within the housing assembly.
Suitable Applications
Ideal for:
- Major civil construction & infrastructure projects
- Mining support operations & heavy ground engineering
- Piling preparation & foundation drilling
- Utility infrastructure installation
- Government & tier-1 contractor fleet applications
- Heavy commercial construction works
