Rotary drilling rig 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, and 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.

7 Core Features of Hydraulic Rotary Drilling Rig
- Full Hydraulic Drive & Powerful Drilling Performance: This hydraulic rotary rig adopts a full hydraulic power system, providing strong rotary torque and high drilling pressure. It easily drills through clay, sand layer, pebble layer, and soft rock strata, ensuring fast and stable hole forming.
- High Piling Efficiency & Fast Construction Speed: Integrated drilling and soil discharging design greatly shortens single-hole forming time. Its continuous working capacity is 2–3 times higher than that of traditional drilling machines, effectively speeding up project progress and shortening construction periods.
- Stable Drilling Quality & Low Defect Rate: Precise hydraulic control ensures vertical drilling with low hole deviation. The finished pile holes are neat and uniform, effectively reducing pile rework rate and improving overall foundation construction quality.
- Strong Terrain Adaptability: Equipped with a sturdy crawler walking system, the rotary drilling rig adapts to muddy construction sites, uneven mountain terrain, and complex road conditions. It can move freely and position accurately on various harsh working grounds.
- Low Vibration & Low Noise Environmental Operation: Different from high-impact drilling equipment, hydraulic rotary drilling works with low vibration and low noise. It meets urban environmental protection standards and supports construction near residential areas and dense urban buildings.
- Intelligent Operation & High Safety: Equipped with an intelligent monitoring panel, real-time display of drilling depth, torque, and working status. It supports overload protection and automatic shutdown functions, greatly reducing construction safety risks.
- Durable Structure & Low Maintenance Cost: Thickened heavy-duty main body and wear-resistant drill tools extend service life. The modular structure design makes daily inspection and parts replacement simple, lowering long-term operation and maintenance costs.

Real Customer Cases about Rotary Drilling Rig Machine
Case 1: New Customer – Philippine Municipal Contractor
- Customer Background: A local municipal engineering contractor in Manila, Philippines, specializes in urban road renovation, small bridges, and residential foundation piling projects, requiring flexible and lightweight piling equipment for narrow urban sites.
- Difficulties: Urban construction spaces are limited; traditional large rigs cannot enter narrow working zones. Local soft soil strata easily cause hole collapse, and old equipment has unstable drilling depth and low efficiency.
- Solution: We recommended the YG13 hydraulic rotary drilling rig, featuring 13m max drilling depth, 1000mm drilling diameter, 360° full rotation, and only a 9-ton lightweight body, perfectly fitting narrow urban construction and local soft geology.
- Effect: The compact 3.1×1.92×3.5m dimension enables free access to tight sites. 360° rotary angle improves positioning flexibility. Steady 50KN · m torque effectively prevents hole collapse, fully meeting municipal piling standards.
- Customer Feedback: “This small hydraulic rotary rig is ideal for Philippine urban projects. Flexible movement and stable drilling quality greatly improve our working efficiency.”
Case 2: Repeat Order – Polish Infrastructure Company
- Customer Background: A large Polish infrastructure firm undertaking highway viaduct and industrial park foundation projects. It is our old customer and placed a repeat order for capacity expansion.
- Difficulties: The company undertook multiple large foundation projects requiring deeper drilling and larger pile diameters. Previous small rigs could not meet 20m deep piling demands, restricting project expansion.
- Solution: We supplied the heavy-duty YG20 rotary drilling rig machine, with 20m maximum drilling depth, 1600mm max diameter and 360° full rotation, meeting European high-standard deep foundation construction requirements.
- Effect: The 17.8-ton heavy-duty machine runs stably for long continuous operation. Deep drilling capacity completely solves depth limitation problems, helping the customer finish large-scale bridge foundation piling efficiently.
- Customer Feedback: “We repurchase this hydraulic rotary drilling rig for its reliable performance. It perfectly supports our large highway projects with stable output and low failure rate.”
