Self-Propelled Crawler Water Well Drilling Rig 300m Depth 105-350mm Borehole JKS300B

The JKS300B self-propelled crawler water well drilling rig is a compact hydraulic machine built for contractors who need dependable drilling capacity without the cost and logistics of a truck-mounted unit. Its full hydraulic drive train uses a high-pressure variable displacement pump to deliver stepless rotation speed, which removes heavy gearboxes, trims overall weight and makes the rig easier to maintain in remote locations. The machine travels on heavy-duty rubber crawler tracks that spread ground pressure evenly, allowing safe movement across soft farmland, muddy riverbanks and loose gravel. Once on site, the operator can level the rig with hydraulic supporting legs and be drilling within a single working shift, with no crane or auxiliary equipment required.

• Dual drilling modes: switch between DTH hammer with compressed air flushing for hard rock and rotary cutting bits with mud circulation for soft strata, all from the same mast.
• Stepless rotation: high-pressure variable pump delivers 0-40/80rpm rotation with 8500N.m torque, simplifying the drive train and reducing fuel consumption.
• Compact footprint: 6300x2000x2300mm transport dimensions let the rig pass through narrow village roads, orchard lanes and gateways.
• Fast pipe handling: built-in small winch with 1.5T lifting force speeds up drill pipe makeup and breakout, reducing crew fatigue.
• Crane-free setup: hydraulic supporting legs and a foldable mast allow erection on site without any lifting equipment.
• Field power options: optional 24kW/380V hydraulic generator and 20L/min foam pump support auxiliary tools and foam drilling.

The JKS300B is widely used for rural drinking water wells, livestock watering holes, small-scale irrigation boreholes, geothermal probes and monitor wells. Its compact size and high-speed small-diameter drilling capability also make it a practical choice for geological exploration, gas drainage, water drainage, trenchless crossing and anchoring support operations in confined construction zones.

The rig is shipped in export seaworthy packing with steel frame support, plastic film wrapping and anti-rust treatment on all exposed hydraulic parts. Every machine passes a full hydraulic pressure test, rotation test and track inspection before loading. We provide a one-year warranty on major components, complete operation and maintenance manuals, and remote technical support for first-time assembly and subsequent rig relocation.
