Import Blast Hole Drill Rig — Buy in Bulk from Supplier in India

The Revathi C370R blast hole drill rig is a track-mounted rotary drilling system designed for open-pit mining and quarry operations, capable of drilling holes from 270 mm to 311 mm in diameter. It uses a top-head drive system with planetary gear reduction to deliver consistent torque under heavy load, with a maximum pull-down force of 80,000 lbs and a 43-foot head travel to handle 40-foot drill pipes. The rig is powered by a Cummins QSK23 or Caterpillar C23 diesel engine, rated at 800 HP, driving both hydraulic pumps and a 1880 CFM screw compressor for air blast operations.

The drill features a welded steel mast with a working height of 52 feet 2 inches, supported by twin hydraulic cylinders and safety check valves. Feed rates range from 12 FPM standard to 80 FPM fast, with hoisting speeds up to 170 FPM. The hydraulic system uses open-loop circuits with axial piston pumps, delivering 58 GPM for tram and rotation, and 18 GPM for feed. The operator cab is fully enclosed, sound-suppressed to 85 dB, and equipped with joystick controls and climate control. Dust extraction is managed by an NVE-type dry filter system with a hydraulic suction blower.

This rig is typically purchased by mining contractors in Southeast Asia, Africa, and Latin America for large-scale blast hole patterns in hard rock. Buyers require full compliance with EPA Tier III emissions standards and robust undercarriage for steep terrain. Standard configuration includes four drill pipes, spindle subs, bit and hammer subs, and a hydraulic winch. Optional upgrades include an electronic depth counter, central lubrication, and fire suppression. Trade terms are usually FOB Coimbatore Port, with lead times of 10 to 14 weeks after deposit.

Revathi Equipment Ltd. is based in Coimbatore, Tamil Nadu, India, and manufactures heavy mining equipment for blast hole drilling. The company is listed as an imported supplier with harbor trust tier status, but provides no details on years in operation, workforce size, or production volume. Its product listing confirms capability to build and ship the C370R model with standard and optional configurations, but does not reference ISO certification, export history, or client testimonials. The supplier’s address is verified through local business registries, and the company operates as a direct manufacturer without third-party distribution claims.

There is no public information regarding the company’s testing protocols, quality control procedures, or after-sales service network. The listing does not mention spare parts availability, training programs, or technical support hours. Buyers should request a factory acceptance test report and a list of included spare parts before shipment. The absence of a response rate or reply time suggests limited customer service infrastructure, making direct engineering coordination essential prior to purchase.
