Integrated Crawler-Mounted Photovoltaic (PV) Screw Piling Rig
Undercarriage: Heavy-duty steel crawler chassis with reinforced track rollers and idlers; low ground pressure prevents sinking in muddy or soft terrain; designed for steep slopes, capable of operating on mountain gradients up to 30°.
Power System: Yuchai diesel engine paired with a dual-pump combined hydraulic system; delivers abundant power while ensuring energy efficiency and low noise; standard hydraulic overload protection prevents engine stalling due to drill jamming.
Rotary Main Frame: 360° rotating superstructure; mast allows for multi-angle pitch adjustment, accommodating elevation differences and inclined piling on slopes.
Power Head Assembly: Hydraulic motor plus two-stage planetary gearbox; output torque ranges from 5,000 to 7,000 N·m; features wear-resistant sealing for long-term durability in field operations.
Drill Rods and Bits: Thickened manganese steel auger rods and wear-resistant alloy teeth; allows for quick swapping of rods with different diameters; dual-interface options (flange/pin) accommodate various types of screw piles.
Control System: The entire machine can be operated by a single person.
Eight Core Product Advantages
1. Extremely High Construction Efficiency; Significantly Shortened Project Timelines
Installing a single 2-meter PV screw pile takes only 30–60 seconds, with a daily capacity of 300–800 piles; compared to manual hole digging and concrete formwork/pouring, the construction period is reduced by over 70%, making it ideal for the rapid, large-scale installation requirements of major PV power plants.
2. All-Terrain Adaptability; Handles Complex Working Conditions
Stable operation on plains, deserts, saline-alkali land, and soft riverbed silt;
Optimized climbing and inclined drilling capabilities for mountainous areas, hills, terraced fields, and steep slopes;
Suitable for diverse applications, including agrivoltaics, fishery-PV hybrid systems, distributed rooftop PV, and small-scale residential PV installations.
3. Lower overall construction costs
Eliminates the need for rebar, cement, sand, gravel, formwork, and curing processes, saving on raw materials and curing time. The piles can be fully extracted and recycled for land reclamation later at minimal cost, aligning with land-use policies for photovoltaic projects.
4. High hole-forming precision and pile stability
Features a built-in verticality correction mechanism, ensuring a verticality error of ≤1°. The spiral extrusion process creates highly compacted pile holes; the resulting piles offer excellent pull-out and compressive load-bearing capacities, preventing risks such as racking settlement or tilting and meeting stability requirements for PV systems.
5. Eco-friendly with minimal soil disturbance
Construction generates no dust or slurry discharge; the process relies primarily on in-situ soil displacement with minimal spoil removal, preserving the original soil structure. Operational noise is lower than that of traditional impact pile drivers, offering significant advantages for environmental compliance when working near farmland or villages.
6. Versatile and highly adaptable
By simply changing the drilling tool, the machine can perform various tasks: installing PV screw piles, pre-drilling foundation holes, boring holes for utility poles, digging planting pits, and geological sampling. This maximizes equipment utilization without requiring additional investment in machinery.
7. Rugged durability and field adaptability
Key structural components undergo heat treatment for wear resistance, and drilling teeth are individually replaceable. The hydraulic system features dustproof and waterproof designs, ensuring low failure rates during long-term, continuous operation in harsh outdoor environments-including high heat, extreme cold, and windy/sandy conditions-while simplifying maintenance.
8. Low operational barrier and reduced labor costs
The integrated unit can be operated by a single person; novices can get up to speed with minimal training, eliminating the need for specialized piling operators and reducing the overall labor force required for the crew.
