Rotary piling machines are construction machines suitable for hole-forming operations in building foundation engineering. They are primarily suitable for construction in soil layers such as sand, cohesive soil, and silty soil. They are widely used in various foundation constructions, including cast-in-place piles, continuous walls, and foundation reinforcement. It is an engineering machine that uses a hydraulic power system as its core, driving the drill rod and drill bit to rotate and cut through rock and soil via a power head. It uses a drill bucket to extract soil and circulates the operation to ultimately complete the hole-forming of the pile foundation. It integrates mechanical, hydraulic, and electrical control technologies and is suitable for pile foundation construction in buildings, bridges, railways, highways, and other engineering projects.

Case 1: Export to the United States — YG13 Compact Rotary Drilling Rig
1. Customer Background & Identity
The customer is a local medium-sized foundation engineering contractor headquartered in Texas, USA, mainly engaged in shale gas well site construction, small industrial plant foundation projects and suburban commercial building piling work. As North America is the world’s largest rotary drilling rig market, accounting for 38.7% of global market share, the company undertakes numerous scattered infrastructure renovation and energy supporting construction projects. The contractor previously used outdated heavy-duty drilling equipment and intended to purchase a flexible, low-failure hydraulic rotary drilling rig to replace old machines, improve construction efficiency and meet local strict construction emission and safety standards.
2. Key Difficulties Encountered
- Most construction sites are narrow suburban industrial zones and well-site temporary yards, large rotary drilling rigs cannot flexibly turn and transfer, and the transportation cost of oversized equipment is extremely high.
- Local shale and soft soil geology is prone to hole collapse during piling; old equipment with fixed rotary speed cannot adjust drilling parameters according to stratum changes, resulting in unqualified hole forming and frequent project rework.
- Small-scale foundation projects only require shallow pile construction within 15 meters, large torque heavy rigs lead to high fuel consumption and serious equipment idle waste, greatly raising operating costs.
- The United States has strict noise and exhaust emission requirements for construction machinery; traditional drilling equipment fails to meet local environmental inspection standards, restricting the scope of project bidding.
3. Targeted Solution: YG13 Rotary Drilling Rig Matching Local Demand
Combined with North America’s market characteristics and the customer’s project attributes, we recommend the YG13 rotary drilling rig machine:
- YG13 features a compact overall dimension of 3.1×1.92×3.5m and a total weight of only 9 tons, supporting highway transportation and rapid transfer between scattered well sites and suburban construction plots, which greatly cuts vehicle transportation and road approval costs for oversized equipment.
- This model is equipped with a maximum drilling depth of 13m and a maximum drilling diameter of 1000mm, perfectly matching the shallow foundation construction demand of industrial parks and shale gas auxiliary facilities in Texas; the maximum rotary torque reaches 50KN·m, which can easily cope with local shale, clay and loose sandy strata.
- The adjustable rotary speed ranges from 10 to 45r/min, and the 360° full-range rotary angle allows flexible drilling in narrow working areas. Operators can adjust rotation speed in real time according to geological conditions to effectively prevent hole collapse and ensure one-time qualified hole forming.
- The whole machine adopts low-emission power configuration, meets North American environmental protection standards, helps the customer pass construction site environmental audits, and expands the range of government and energy enterprise bidding projects. We provide English operation manuals, remote technical training and a full set of vulnerable spare parts to solve the difficulty of local after-sales maintenance.
4. Actual Operation Effects
- Compact body realizes fast cross-site transfer, the equipment relocation cost is reduced by 62%, and the daily number of pile forming rises from 5 piles to 11 piles, significantly shortening the construction cycle of each project.
- Adjustable rotary speed effectively avoids hole collapse accidents in shale strata, the one-time acceptance rate of pile holes reaches 100%, and the rework loss caused by unqualified hole forming is completely eliminated.
- The small-tonnage design avoids equipment idle and excessive fuel consumption, the daily fuel cost is reduced by nearly 40%, and the comprehensive project profit margin is significantly improved.
- The low-emission configuration meets local regulatory requirements, the customer successfully obtained bidding qualifications for three energy infrastructure supporting projects, and the company’s market competitiveness in the southern United States has been greatly enhanced.
5. Customer Feedback
“Our YG13 rotary piling machine perfectly adapts to our scattered industrial and shale gas foundation projects in Texas. Its compact size saves us a huge amount of transportation and site use costs, and the strong 50KN·m rotary torque handles local complex shale geology very well. The adjustable rotating speed ensures stable hole forming quality, and the low-emission design helps us win more government construction tenders. We will recommend this reliable hydraulic rotary drilling rig to our peers in Oklahoma and Louisiana, and we plan to place a repeat order for two more units within this year.”
