Product Q&A

Q:What is the difference between RC and forward circulation drill rigs?

RC drill rigs use 'outside-in' circulation, offering 30%-50% faster slag discharge and less sediment, making them suitable for large-diameter, deep-hole operations in complex formations like pebble and hard rock. Forward circulation is limited to shallow, small-diameter drilling in soft formations.

Q:What formations can the RC drill rig work on?

The rig has strong adaptability and works in clay, sand, pebble layers, cemented gravel, medium weathered rock, and hard rock. It is also suitable for arid, water-scarce, and remote areas.

Q:What are the maximum drilling depth and diameter?

Standard models support a drilling diameter of 105-3000mm and a depth of 50-1200m. Customized services are available for deeper depths or larger diameters based on specific project needs.

Q:What after-sales services are provided?

We offer 24/7 online technical support, a one-year warranty with long-term coverage for core components, free installation and maintenance guidance, fast delivery of original spare parts, and overseas engineering support for debugging and training.

Q:What certifications does the machine have?

The machine is certified with ISO 9001:2000.
