High-Speed Telescoping Mast Water Well Drilling Rig 380m 6800mm Feed Stroke JKS380S

The JKS380S high-speed telescoping mast water well drilling rig is engineered for drilling teams that move between multiple sites every week. Its mast extends hydraulically to a full working height while the machine stays on a compact transport package, so the rig can be towed or trailered through mountain roads without special permits. A long 6800mm feed stroke reduces the number of pipe connections per hole, which cuts cycle time and lowers the physical workload on the crew. The hydraulic supporting legs have a 1650mm stroke, letting the operator level the machine quickly on slopes and uneven ground before the mast is raised, a decisive advantage in hilly terrain and narrow valleys.

• Long feed stroke: 6800mm stroke means fewer rod joints per hole, faster tripping and less wear on threads and shoulders.
• Telescoping mast: the mast retracts for transport and extends on site, keeping the transport height under 2650mm for easy logistics.
• High rotation speed: 0-40/80rpm stepless rotation with 8500N.m torque balances fast penetration with control in fractured formations.
• Strong pullback: 18T maximum lifting force and 1.5T small winch handle stuck tools and heavy drill strings confidently.
• Self-leveling legs: 1650mm hydraulic support leg stroke levels the rig on slopes up to 15 degrees without cribbing.
• Centralizer guidance: adjustable centralizer at 0.8m height keeps boreholes straight in dipping and faulted ground.

The JKS380S is a proven performer for mountain water supply projects, rural community wells, slope stabilization drilling, gas drainage holes and small geothermal loops. The combination of a telescoping mast, long feed stroke and steep grade ability makes it especially suitable for sites in hilly and rocky regions where access roads are narrow and crane support is unavailable.

Each JKS380S is delivered with export-grade packing, including steel frame reinforcement, waterproof wrapping and corrosion protection for hydraulic cylinders and hose fittings. The rig undergoes a 48-hour hydraulic system test, mast extension test and track tension check before shipment. One-year warranty, spare parts kit, bilingual manuals and online commissioning guidance are included with every order.
