The rotary piling rig is professional foundation piling equipment for high-rise buildings, municipal bridges, and infrastructure projects, with four models covering 13–20m drilling depth and 1000–1600mm pile diameter. Equipped with 36–50KN·m stable rotary torque and adjustable rotating speed from 10 to 46r/min, it efficiently handles clay, sand, and weathered rock strata. Two rotary designs (180° and 360°) adapt to narrow urban sites and linear road construction. Compact YG13 only weighs 9 tons for easy cross-region transportation, while heavy YG20 meets European high-standard deep piling demands. Featuring stable hydraulic systems, low fuel consumption, and flexible crawler transfer, this rotary piling machine has gained wide popularity in North America, Europe, Southeast Asia, and so on for its high hole-forming accuracy and long service life.

Case 1: Customer from the Philippines
1. Customer Background & Identity
The client is a local medium-sized foundation engineering contractor based in Manila, Philippines, mainly undertaking residential buildings, municipal roads and small commercial building pile foundation projects. The company frequently undertakes scattered urban construction tasks and island infrastructure projects, requiring a flexible and compact hydraulic rotary drilling rig for small and medium pile construction. Before cooperation, the customer used old-fashioned percussion drilling equipment and intended to replace it with a high-efficiency rotary piling machine to improve project bidding competitiveness.
2. Difficulties Encountered
- Low construction efficiency of old percussion equipment: It can only drill to 10 meters deep at most, failing to meet the 12–20m pile depth requirements of local high-rise buildings, resulting in frequent project delays.
- Limited narrow urban construction sites: Large drilling equipment cannot enter residential block construction zones, and the old machine has too large an overall dimension to turn freely.
- Unstable hole-forming quality: Underground sandy soil strata easily cause hole collapse, and the old equipment lacks an adjustable rotary speed to cope with complex geological conditions.
- High equipment transfer cost: The previous heavy drilling machine could not be transported by small inter-island barges, leading to extra high freight for cross-island engineering projects.
3. Targeted Solutions Combined with Technical Parameters
We recommended YG13 and YG20 rotary drilling rigs for this customer according to local pile construction standards and transportation conditions:
- Adopt the YG13 model with a maximum drilling depth of 13m, drilling diameter 1000mm, total weight 9 tons and dimension 3.1×1.92×3.5m; its compact body supports small barge transportation and free operation in narrow urban sites, with a 360° rotary angle to realise multi-directional pile drilling.
- Equip YG20 rotary drilling rig with 20m maximum drilling depth and 1600mm drilling diameter for high-rise building foundation projects; the machine is matched with 36kN·m rotary torque and 22–43r/min adjustable rotary speed to adapt to local sandy soil and clay strata.
- Provide remote parameter debugging training, teach operators to adjust rotary speed to prevent hole collapse, and deliver complete wearing parts to solve the difficulty of spare parts procurement in the Philippines.
- Offer a detailed equipment operation manual and a one-year global warranty service to reduce the customer’s post-purchase maintenance risk.
4. Operation Effects
- Greatly improved construction efficiency: The hourly pile forming speed is increased by 70% compared with the old percussion drilling machine, and the daily pile construction quantity rises from 6 piles to 12–15 piles.
- Perfect adaptation to narrow and cross-island transportation: YG13 compact rotary drilling rig can be loaded on small transport vehicles and inter-island barges, cutting equipment transfer cost by 55%.
- Stable hole forming quality: Adjustable 10–45r/min rotary speed effectively avoids sandy stratum hole collapse, and the 360° rotary angle ensures verticality of all pile holes, fully passing local engineering acceptance inspection.
- High equipment utilization rate: Two sets of rotary drilling rigs undertake urban, suburban and island engineering projects simultaneously, and the customer successfully won 3 more municipal foundation bidding projects.
5. Customer Feedback
“Our YG13 and YG20 hydraulic rotary drilling rigs have completely solved our construction and transportation troubles in the Philippines. The reasonable rotary torque and adjustable rotating speed adapt perfectly to local complex soil layers. The compact structure makes equipment transfer much easier, and the stable performance helps us win more foundation orders. We will purchase more rotary piling machines for our branch teams in Visayas and Mindanao regions and highly recommend your rotary drilling rig machine to local engineering partners.”
Case 2: Customer from Madagascar
1. Customer Background & Identity
The buyer is an infrastructure contractor headquartered in Antananarivo, Madagascar, mainly engaged in rural highway reconstruction, factory construction and port auxiliary pile foundation projects. Local geological conditions are complex, including swamp peat soil, weathered rock and gravel interbedded strata. The customer needed a durable rotary drilling rig machine with strong torque to complete pile drilling in variable geology, and previously compared multiple brands of hydraulic rotary drilling rigs before final cooperation.
2. Difficulties Encountered
- Complex and changeable geological conditions: Swamp soft soil and weathered rock alternately appear; ordinary drilling rigs have insufficient rotary torque, leading to slow drilling and frequent drill jamming.
- Uneven construction road conditions: Most rural construction sites have no hardened roads, and overweight drilling equipment is easy to sink and cannot move flexibly.
- Inconsistent pile diameter and depth requirements: Highway bridge piles need 15–16m drilling depth and 1500–1600mm pile diameter, while factory foundation piles have diversified parameter standards.
- Lack of professional after-sales service locally: Once the drilling rig fails, spare parts are difficult to purchase, which will cause long-term construction shutdown losses.
3. Targeted Solutions Combined with Technical Parameters
We selected YG15 and YG16 rotary drilling rigs matching the customer’s project requirements:
- Deploy the YG15 model with a maximum drilling depth 15m, drilling diameter 1600mm, 45kN·m high rotary torque and 17–45r/min rotary speed; strong torque effectively breaks weathered rock and gravel strata to avoid drill sticking.
- Configure YG16 hydraulic rotary drilling rig with 16m drilling depth, 1500mm drilling diameter and 46kN·m rotary torque to meet factory foundation pile construction; the 180° rotary angle is suitable for limited operation space beside rural highways.
- The two machines weigh 13 tons and 11 tons respectively, with reasonable weight distribution to prevent sinking on muddy rural construction roads, and the overall dimensions are convenient for off-road vehicle traction transfer.
- Equip a full set of vulnerable spare parts, including drill bits, hydraulic seals and drill pipes, provide 24-hour online technical guidance, and formulate parameter adjustment schemes for local swamp and rock strata.
4. Operation Effects
- Efficient drilling in complex geology: High rotary torque successfully solves drill jamming problems in weathered rock and gravel layers, and the single pile drilling time is shortened by nearly half.
- Strong off-road transfer adaptability: Reasonable equipment weight avoids sinking on muddy rural roads, enabling fast transfer between multiple highway construction sections.
- Wide construction parameter coverage: The two models can realise 1000–1600mm pile diameter and 13–16m drilling depth, covering all the customer’s highway and factory pile foundation construction demands.
- Low equipment failure rate: Standardised hydraulic system and pre-delivered spare parts ensure continuous construction, and no long-term shutdown caused by equipment failure occurs during the whole project period.
5. Customer Feedback
“These rotary piling machines bring huge benefits to our infrastructure projects in Madagascar. The high rotary torque design perfectly adapts to our local swamp and weathered rock geology, greatly improving our pile forming efficiency. The equipment moves flexibly on rural muddy roads, and the complete spare parts package eliminates our worries about after-sales maintenance. We plan to expand our construction scale and place repeated orders for your hydraulic rotary drilling rig in the near future.”
