Product Description
The DR500 Water Well Drilling Rig is a high-capacity hydraulic crawler drilling machine developed for deep water well construction, geothermal energy projects, mining exploration and large-scale infrastructure applications. With a maximum drilling depth of 500 meters and borehole diameters up to 400mm, the DR500 is designed to deliver exceptional drilling performance in demanding geological environments.
Powered by a reliable 118kW Cummins diesel engine, the rig combines strong lifting capacity, powerful rotary torque and advanced hydraulic control technology. Its heavy-duty structure ensures stable operation during deep drilling projects while maintaining high productivity and operational efficiency.
Engineered for Deep Borehole Drilling
Designed for professional drilling contractors, the DR500 is capable of handling complex drilling conditions where standard rigs may struggle. The machine supports drill rods up to 114mm in diameter and lengths up to 6 meters, making it highly effective for deep borehole construction and large-diameter water wells.
Its reinforced mast system and heavy-duty hydraulic components are built to withstand continuous operation under high loads, providing excellent reliability in long-term projects.
High-Power Rotary System
The DR500 features a rotary head capable of delivering up to 10,000N.m of torque, allowing efficient drilling through hard rock formations and difficult geological structures. The adjustable rotary speed range provides flexibility for different drilling techniques and formation types.
Combined with a lifting force of 26 tons, the machine offers superior handling of heavy drill strings and drilling tools, ensuring safe and efficient operation throughout the drilling process.
Flexible Drilling Methods
One of the key advantages of the DR500 is its ability to operate with either air compressor drilling or mud pump drilling systems. This flexibility enables contractors to adapt the machine to various geological conditions, improving drilling efficiency and reducing project limitations.
Whether working in fractured rock, gravel layers, clay formations or mixed geological environments, the DR500 provides dependable performance and excellent drilling results.
Built for Large-Scale Projects
With a machine weight of 11.5 tons and a heavy-duty crawler chassis, the DR500 offers exceptional stability during drilling operations. The hydraulic support legs further enhance machine balance and safety when working on uneven terrain.
The combination of deep drilling capability, powerful hydraulic performance and durable construction makes the DR500 an ideal solution for demanding drilling projects worldwide.
