"Yugong Group" has officially unveiled its latest innovation — the RC Reverse Circulation (RC) Crawler Drilling Rig — a new-generation drilling solution engineered for efficiency, environmental friendliness and versatility in geological exploration.
A New Benchmark in Sampling Drilling
The RC drilling rig is a crawler-mounted, multi-functional drilling machine designed to deliver clean, representative ore samples with exceptional accuracy. By employing "double-wall drill pipes", it collects ore powder through the inner tube and conveys it directly to the "cyclone collector", ensuring contamination-free samples that meet the strict demands of geological exploration departments for sampling and analysis.
Working Principle: Air-Powered, Hydraulically Driven
This drilling rig performs "compressed-air reverse circulation down-the-hole (DTH) drilling" across a wide range of strata. Every critical action — drill mast lifting, mast compensation, drill pipe loading and unloading, rotation and feeding, outriggers, winch operation and crawler walking — is powered by a reliable "hydraulic system". This fully hydraulically-driven design significantly reduces operator labor intensity while enhancing construction efficiency and overall project quality.
Key Features
1. High-Efficiency Air Supply & Slag Discharge
An integrated air compressor handles both air supply and slag discharge. The rig can be matched with various DTH hammers and bits according to the working hole size, offering maximum flexibility across different drilling conditions.
2. Low Failure Rate, High Torque & Adjustable Speed
Engineered for durability, the rig delivers large torque with a low failure rate. Rotation speed can be precisely adjusted to suit different working conditions, effectively boosting impactor footage efficiency.
3. Independent Hydraulic Oil Radiator
The hydraulic system is equipped with an independent radiator to ensure continuous, stable operation even under high-temperature outdoor climate conditions — no more downtime caused by overheating.
4. Compensation Cylinder for Superior Rigidity
When the rig is operating, the movable slide presses firmly against the ground working surface through the sliding of the compensation cylinder. This enhances the rigidity and working stability of the entire machine, even on uneven terrain.
5. Reliable Air Pre-Filtration System
The efficient air pre-filtration system filters out dust from intake air, is easy to clean and maintain, reduces engine wear, extends service life, and boosts overall work efficiency — making the rig highly suitable for harsh working conditions.
Applications
The RC Reverse Circulation Drilling Rig is ideal for:
- Geological exploration and mineral sampling
- Ore body delineation and resource evaluation
- Environmental and engineering geology investigation
- Large-scale drilling projects requiring high-speed, high-quality sample recovery
