All customized products are with high quality and competitive price.

The crawler full hydraulic core drilling rig is the main equipment for photovoltaic power stations in mountainous, Gobi and complex terrains. Equipped with a crawler chassis, high-torque spiral drill, it enables stable construction across all terrains. It is applicable for mounting spiral ground piles, steel pipe piles and rock pilot holes, delivering far higher efficiency and adaptability than four-wheel models.

Chassis: Equipped with 300–400 mm wide heavy-duty steel crawler tracks, featuring low ground pressure and a climbing capacity of 15–25°. It never gets stuck in muddy, Gobi or mountainous areas. Two types are available: standard crawler (3–4 tons) and widened & lengthened crawler (4–6 tons, for steep slopes and soft foundations).

Power: Powered by 4-cylinder diesel engines (4105/6105, 110-125HP); 6-cylinder or turbocharged engines are optional for high-end models. The hydraulic system pressure ranges from 16 to 20 MPa, with a torque of 1.2–2.0 t·m, 30%–50% higher than that of four-wheel equipment.

All-terrain Adaptability: It travels smoothly in mountainous areas, slopes, Gobi deserts and muddy lands, accessing locations unreachable by four-wheel machines.

Superior Stability: The combination of crawler tracks and hydraulic outriggers ensures stable operation, high verticality of piles and excellent piling quality.

High Torque & High Efficiency: With powerful spiral torque, it handles hard soil and gravel layers easily. Its daily output is 20%–40% higher than four-wheel equipment.

Multi-functional Integration: It supports spiral pile driving, steel pipe pile piling and rock drilling, with strong universal performance.

Mountain & Hilly Photovoltaic Power Stations: Suitable for complex terrain with a slope of 15°–35%, where four-wheel machines cannot operate.

Gobi & Desert Photovoltaic Projects: Ideal for sand and hard soil layers, equipped with high-torque spiral drills or down-the-hole drills.

Large-scale Ground Photovoltaic Power Stations: Meets the demands of large workloads, tight schedules and high construction standards.

Agricultural-Photovoltaic Complementary & Fish Pond Photovoltaic Projects: Crawler design prevents sinking on soft foundation and muddy ground.

Geological Conditions: Standard models for ordinary soil; widened crawlers + hydraulic outriggers for mountainous and sloped areas; high-torque units + down-the-hole drills for hard rock and weathered rock.

Project Volume: High-end models for large-scale and long-term projects; standard models for small and short-term construction.

Transition Demand: Crawler type for centralized construction sites with less relocation; four-wheel type for scattered sites requiring frequent transition.

• Fill grease at all key lubrication points, including boom pin shafts, slewing bearings, connecting rods, walking bearings and power head bearings to avoid abrasive wear.
• Inspect the appearance of hydraulic and diesel filter elements, and clean them with air blowing if dirty.
• Check the wear of crawler bolts, drive wheels, guide wheels and carrier rollers.
• Tighten all connecting bolts of the frame, outriggers and cab.
• Test the hydraulic outriggers, rotating and traveling functions to eliminate stalling and abnormal noise.

Engine Maintenance
New machine running-in period: Replace engine oil and oil filter after 20 working hours for the first maintenance.
Replace engine oil and oil filter every 50 hours.
Replace diesel filter and air filter every 100 hours.
Replace antifreeze and check belt tension every 200 hours.

Hydraulic System (Core Parts)
First replacement of hydraulic oil and hydraulic filter after 100 working hours for new equipment.
Replace hydraulic oil and return oil filter every 300–500 hours in regular use.
Drain sediment and water at the bottom of the hydraulic oil tank monthly.

Crawler Travel System
Inspect the gear oil of travel reducers and replenish oil in time every 200 hours.
Replace travel reducer gear oil every 500 hours.
Regularly clean sediment on crawler tension cylinders to prevent rust and jamming.
