Hydraulic Core Drilling Machine
What Is a Fully Hydraulic Core Drilling Rig?
A fully hydraulic core drilling rig is a professional hydraulic-powered geological drilling machine. It adopts full hydraulic control for rotation, feeding, lifting, and walking, paired with thin-wall diamond wireline coring technology. It ensures low deviation, high core recovery, and precise rock sampling.
YG hydraulic core drilling rigs are crawler-mounted with 0–90° multi-angle drilling masts. They require no foundation, feature fast hole positioning and flexible movement, and cover drilling depths from 180m to 1100m for various geological projects.
Full Hydraulic Drive & Stable Drilling
Stepless hydraulic speed regulation enables smooth, low-vibration drilling. Built-in pressure monitoring and overpressure protection improve safety, while the simple hydraulic system reduces maintenance costs.
High-Efficiency Wireline Coring
The optimized thin-wall bit lowers torque resistance for faster drilling. The rigid drill string controls hole deviation effectively, delivering large-diameter cores and high recovery rates with fewer drilling accidents.
Integrated Compact Structure
One-piece ground-touching tower needs no repeated assembly. The long-stroke feeding design avoids frequent rod reversing, supporting accurate directional drilling and adapting to narrow job sites.
Remote Control Crawler & Strong Adaptability
Supports manual and remote control walking. 45° max climbing angle adapts to complex mountain and field terrains. Dual air-water cooling ensures stable long-hour operation under heavy loads.
Safe & Eco-Friendly
Hydraulic overload protection prevents equipment damage. Foundation-free installation, low noise, and zero pollution meet green construction standards.

Small Well Drilling Rig
How to Choose: Wheel Type or Crawler Type Small Well Drilling Rig?
Choose Wheel-Type (YG-150) If:
Flat & narrow working sites: Choose the wheel-type YG-150. Lightweight (550KG) and towable, it suits flat roads, yards, indoor and urban narrow spaces, enabling fast transfer and flexible light-duty drilling at a lower cost.
Choose Crawler-Type (YG-HY200) If:
Complex & rough terrains: Choose the crawler-type YG-HY200. Equipped with independent walking power and a stable crawler chassis, it adapts to mountains, muddy roads, and slopes, delivering stable performance for long-duration field drilling work.

Reverse Circulation Drilling Rig
A reverse circulation drilling rig (RC drilling rig) is a high-efficiency, eco-friendly crawler hydraulic drilling machine for geological exploration. Unlike core drilling that collects rock cores, RC drilling uses double-wall drill pipes and DTH hammers to crush rock. By compressed air reverse circulation, rock cuttings flow up through the inner pipe and are collected by cyclone separators for accurate depth sampling.
Fully hydraulically controlled, YG RC rigs support both air DTH drilling and mud drilling. They work on loose soil and bedrock, covering drilling depths from 200m to 1200m.
Fast & Accurate Sampling
Continuous reverse circulation delivers complete, depth-matched rock cuttings for lab analysis. Drilling efficiency reaches 10–25m/h, greatly accelerating exploration progress.
Stable & Durable Performance
Ground-fitting compensation cylinders improve overall stability. Protective slide design extends drill pipe life. Equipped with a precision centralizer and level meter, the rig ensures accurate hole opening with wear-resistant sliding structures for long service life.
Fully Hydraulic & Labor-Saving
Hydraulic wrenches and automatic pipe handling enable fast, safe rod connection. Full hydraulic operation lowers labor intensity and improves construction quality.
Strong Adaptability for Harsh Conditions
High-efficiency air pre-filter removes over 90% of dust to protect the engine. Special oil mist devices extend DTH hammer lifespan, ensuring stable operation in complex outdoor environments.
Green & Clean Drilling
Matched dust collection and cyclone separation systems effectively control dust and residue, realizing pollution-free, environmentally friendly construction.
Applications of Reverse Circulation Drilling Rig
Mineral Exploration
Fast cutting sampling and reserve verification for metallic and non-metallic minerals.
Engineering Geological Survey
