JRC500 Rc Air Compressor Type Reverse Circulation Drilling Rig Equipment

Product Description:

The JRC500 Reverse Circulation (RC) Drilling Rig is a state-of-the-art, high-performance drilling solution developed for geological exploration, mineral resource assessment, water well drilling, and environmental studies. It incorporates advanced gas-lift reverse circulation drilling technology, ensuring minimal sample contamination while maintaining high drilling efficiency.

The rig is fully hydraulic, reducing manual labor while enhancing operational precision. With a powerful 132kW Cummins diesel engine, a maximum drilling depth of 500 meters, and 14000 N.M of rotation torque, the JRC500 is built for tough geological conditions. It can operate with DTH (Down-the-Hole) drilling or RC drilling, making it versatile for different drilling applications.

Additionally, the crawler-type chassis provides mobility across rough terrains, while the dust collection system minimizes environmental impact. This combination of power, precision, and efficiency makes the JRC500 an ideal choice for drilling projects that demand accuracy and reliability.
