Main Components

Reverse Circulation and DTH Compatibility Combines RC with DTH technology; air compressor supplies pressurized air for impact drilling and dust collection, delivering contamination-free samples.
Positive Circulation Option Supports positive circulation using standard drilling tools for added versatility in various applications.

Fully Hydraulic System Integration Diesel engine-powered hydraulic controls cover walking, rotation, feed, lifting, legs, compensation, and rod change, ensuring efficient, low-effort operations.
Dual Tube Mechanism Employs reverse circulation hammer and double tubes where pressurized air flows between tubes, expelling cuttings through the inner tube for reliable sampling.

Features Introduction

Product Description

The JRC500 Reverse Circulation Drilling Rig is a full-hydraulic, deep-hole exploration machine designed for high-efficiency geological prospecting and sampling operations. With a drilling diameter range of 105–450 mm and a maximum drilling depth of 500 m, it adopts advanced gas-lift reverse circulation technology to ensure clean, accurate, and contamination-free sample recovery.
The rig integrates a dust collector and cyclone separator to effectively capture rock dust and cuttings, minimizing environmental pollution while improving sampling quality. Powered by a diesel engine, the fully hydraulic system controls walking, rotation, feeding, lifting, compensation, rod handling, winch operation, and leveling legs, significantly reducing labor intensity and enhancing drilling efficiency and construction quality. With excellent mobility, strong terrain adaptability, and versatile drilling capabilities, the JRC500 is an ideal solution for deep-hole applications in exploration, water wells, monitoring wells, and ground source heat pump systems.

Fully Hydraulic Integrated System

Diesel-driven hydraulic controls cover walking, rotation, feed, lifting, compensation, rod loading/unloading, and leveling, ensuring smooth operation with minimal manual effort.

Advanced Reverse Circulation Sampling

Gas-lift reverse circulation combined with DTH technology delivers clean, dry rock cuttings with minimal contamination, ideal for accurate geological sampling and analysis.

Dual-Tube & Multi-Process Capability

The reverse circulation hammer uses a dual-tube structure for reliable sample return, while optional positive circulation allows use of standard drilling tools for versatile applications.

High Mobility & Operational Stability

Self-walking crawler system with 2.5 km/h travel speed and 25° gradeability, supported by hydraulic legs for stable, safe, and precise drilling in rugged terrain.
