JKS500F Crawler Mounted RC Drilling Rig 300m Depth 115-350mm Borehole 9000Nm Torque Water Well Machine

This JKS500F crawler mounted reverse circulation drilling rig is a deep-capability machine that reaches 300 meters with borehole diameters from 115 mm up to 350 mm, making it a strong choice for community water supply projects, irrigation boreholes, and commercial water well programs. The rig produces 9000 Nm of rotation torque and offers two rotation speed ranges, 0-35 rpm and 0-70 rpm, so the operator can match rotary speed to formation conditions from soft alluvium to hard bedrock. With a 132 kW engine and 26 tons of maximum lifting force, the JKS500F handles long drill strings and heavy casing strings safely. The compact 12.5 ton crawler base keeps the machine transportable between rural project sites.

• 300m Drilling Depth: deep water well capability for municipal and agricultural supply projects.
• 115-350mm Borehole Range: covers production wells, test holes, and larger diameter boreholes.
• 9000Nm Rotation Torque: powerful rotary drive for large bits and tough formations.
• 26T Lifting Force: handles long drill strings and casing with a wide safety margin.
• Dual Rotation Speed Ranges: 0-35 and 0-70 rpm settings adapt to different drilling methods.
• 12.5 Ton Compact Base: easy transport and access to remote well sites.

The JKS500F is a proven performer in the water well sector, drilling production wells for villages, farms, schools, and industrial facilities across Africa, Southeast Asia, and Latin America. Its reverse circulation method keeps the hole clean and stable in unconsolidated formations, reducing the risk of collapse and improving well yield. The rig also drills geothermal exchange wells, dewatering wells, and exploration boreholes. Water well contractors value the machine for its combination of depth capacity, hole size range, and road transportability, which allows one rig to serve a wide service territory.

Each JKS500F is factory tested with a lifting test, rotation torque check, and full flushing circuit verification before packing. The rig ships in a 40ft open top container or flat rack with the mast and drill string components secured. Documentation includes the CE certificate, engine compliance papers, operation and maintenance manuals, and a recommended spares list.
