Overview

The JTRC-350 is a high-performance reverse circulation drill rig engineered for 350m deep drilling operations, combining robust Weichai power, superior hydraulic control and professional RC drilling technology. Ideal for hard rock formation drilling, it excels in water well construction, geological exploration, mineral sampling and geotechnical engineering projects worldwide, with a versatile drilling diameter range of 105-400mm to meet diverse on-site demands.

Core RC Drilling Advantages & Key Performance

1. Powerful Drilling Capacity for 350m Depth

Equipped with a Weichai 129kW/2200rpm engine, the JTRC-350 delivers a high rotary torque of 8000-12000N·m and adjustable rotary speed of 40-160rpm, ensuring efficient penetration through complex rock formations. Its 260kN lifting force and 130kN propulsion force provide stable power for deep drilling, paired with 3.3m feed stroke to streamline rod handling and reduce operational downtime.

2. Professional Reverse Circulation System

Fitted with medium and high air pressure series RC hammers, matching a supporting air compressor with 1.7-3.5MPa working pressure and 17-42m³/min air consumption. The RC system ensures clean cuttings recovery and uncontaminated core sampling, critical for accurate geological analysis and aquifer identification in water well projects.

3. Efficient Operation & Flexible Configuration

Boasting 20m/min fast lifting speed and 40m/min fast feeding speed, the rig maximizes daily drilling productivity. It supports customizable drill pipe options (76/89/102mm diameter, 1.5/2/3m length) and a 20kN tool hoist lifting force, adapting seamlessly to different drilling depth and diameter requirements for multi-scenario applications.

4. Rugged Mobility & Stable Terrain Adaptability

With a heavy-duty crawler chassis, the JTRC-350 offers 2-3km/h walking speed and 25° gradeability, enabling reliable deployment on uneven terrain, rural work sites and remote exploration areas. Its compact transport dimensions (5900*2100*2500mm) and 8t overall weight simplify logistics and on-site setup, while the stable working dimensions (4200*3000*6100mm) guarantee safe operation at maximum drilling depth.
