Flexible RCF220W Wheel Type Borehole Drilling Machine for Marine Engineering
Machine Introduction
The RCF220W wheeled water well drilling rig is a versatile and highly efficient lightweight drilling system engineered for diverse applications. Designed for industrial, civil, and geothermal drilling projects, this rig combines a compact structure with rapid propulsion capabilities, ensuring exceptional maneuverability across a broad range of environments. Its pneumatic operation makes it particularly effective for water extraction in rugged terrains, such as mountainous areas and rocky formations, where traditional methods may struggle.
Beyond standard water well drilling, the rig’s adaptability allows seamless integration with air compressors, mud pumps (such as the included BW250 model), or dry hydraulic drilling techniques, enabling precise hole formation in varying geological conditions. Whether tackling soft soil, dense rock, or mixed strata, the RCF220W delivers consistent performance, making it a go-to solution for projects requiring flexibility, speed, and reliability.

Machine Advantages
1. Multifunctional and efficient operation - supports air down-the-hole hammer (DTH), mud pump circulation (standard BW250 pump, flow rate 250L/min) and dry hydraulic drilling, can cope with complex geological conditions such as hard rock and loose strata, with a maximum drilling depth of 220 meters and a hole diameter of 90-300 mm, suitable for industrial water wells, agricultural irrigation, geothermal development and other scenarios.
2. Powerful performance and precise control - equipped with a 65KW diesel engine, providing 3400-4700Nm high torque, combined with a full hydraulic system to adjust the speed, push-pull force and lifting speed (lifting force up to 13 tons) in real time, ensuring the operating efficiency and precision under different working conditions.
3. Stable and flexible design - the wheeled chassis is easy to move the trailer (speed 2.5km/h), and the four-leg structure enhances construction stability; the high-strength low-carbon alloy steel body and professional excavator chassis design are both wear-resistant and long-life.
4. Economical and durable - using DTH down-the-hole hammer technology, the drilling cost per meter is low, and with durable drill pipe (R780 material) and optional hard rock drill bits (such as 152mm three-cone drill bit), the equipment life cycle is extended.
