Products features
Advanced Hydraulic System
The RCJ-3W Rotary Borewell Machine features a fully hydraulic control system for drill rod lifting, lowering, and mast adjustment. Operators can remotely adjust drilling speed and monitor bottom-hole pressure in real time, ensuring safe and efficient operation across different geological conditions.
Good Mobility and Easy Setup
Four hydraulic outriggers lift the rig up to 1.3 meters for easy loading and unloading, while the wheeled traveling device and hydraulic leveling supports allow precise positioning on site. The automatic telescopic mast simplifies tower assembly and disassembly, saving time and enabling operations on slopes, embankments, and other challenging terrains.
Powerful Engine and Versatile Operation
A 24V diesel engine with electric start provides reliable performance in all weather conditions. With 8 forward and 2 reverse speeds, the RCJ-3W Rotary Borewell Machine adapts to different drilling materials and depths. Optional attachments, such as a hydraulic pipe wrench, further reduce manual labor and downtime, making the machine ideal for year-round drilling applications.
Packaging & Shipping
