Direct Overview: The Kaishan KW180 is an ultra-portable, crawler-mounted water well and geothermal drilling rig designed to drill borehole diameters from ⌀140 mm to 254 mm down to a maximum depth of 180 meters. Powered by a fuel-efficient 60–65 kW Yuchai turbocharged diesel engine delivering 4,600 N·m rotary torque and a 12-ton (120 kN) pullback force, it weighs only 5,200 kg with an ultra-narrow 1.63-meter width. Its hybrid "Gas & Water" dual drilling system operates with high-pressure DTH air hammers (17–25 bar) for hard rock and mud rotary pumps for soft soil at penetration rates of 15–35 m/h.
Small-scale agricultural irrigation, rural homestead drinking wells, and residential geothermal HVAC installations frequently encounter narrow entrance gates, village lanes, and fragile lawns where heavy truck-mounted or wide crawler rigs cannot enter. Furthermore, tackling varied geology—ranging from loose alluvial clay, sand, and river pebbles to hard limestone and granite bedrock (f=6–20)—demands flexible, high-penetration tooling.
The Kaishan KW180 is engineered specifically to conquer confined jobsite constraints without sacrificing performance. Featuring an ultra-slim 1,630 mm width and a lightweight 5.2-ton chassis, it maneuvers through residential alleys and garden gates with ease. Operating up to 10 times faster than conventional rotary drills, it enables drillers to switch seamlessly between air hammer percussion and positive-displacement mud circulation on a single, highly economical platform.
Equipped with an industrial 60 kW / 65 kW Yuchai diesel engine paired with an independent hydraulic pump design, delivering strong power output, minimal hydraulic loss, low fuel consumption, and easy worldwide maintenance.
Patented composite arm design with dual lifting cylinders delivers 12T (120 kN) rig lifting power. The 3.0m one-time advance stroke handles standard 1.5m, 2m, and 3m drill pipes with built-in cylinder safety stoppers.
Hydraulic rotary head with speed reducer delivers 3,200–4,600 N·m torque. A fast distribution valve allows 3-gear speed control (45–70 r/min, max up to 150–160 r/min) for both high-pressure air and mud drilling.
Four heavy hydraulic legs provide fast, stable leveling on slopes and rough terrain, allowing the rig to elevate high enough for a flatbed truck to back underneath, enabling crane-free self-loading and unloading.
Weighing only 5.2 tons with a 1,630 mm width, the KW180 features durable rubber tracks (steel tracks optional), minimizing turf and pavement damage while providing a 30° climbing ability in mountainous paths.
Features an integrated dust suppression device suitable for tunnel/cavity applications, customized DTH hammer oil mist lubricator, soft-protected hydraulic hoses, and an intuitive centralized control console.

To achieve maximum penetration across 140–254 mm boreholes down to 180 meters, the KW180 connects with compact portable compressors and mud pumps:
Kaishan LGCY-13/13, LGCY-15/13, or KSCY-550/13 (13–17 bar, 15–18 m³/min) for fast rock penetration with 4"/5" DTH hammers.
BW-160 reciprocating mud pump for borehole wall stabilization and drilling through loose sand, gravel, and clay.
A: The KW180 is rated for drilling depths up to 180 meters (590 ft) with borehole diameters from 140 mm to 254 mm, backed by a 12-ton lifting force mast.
A: Yes. It comes equipped with surface-friendly rubber tracks (steel tracks optional) that maneuver across private lawns, pavers, and asphalt driveways without cracking or damaging the ground.
A: Four high hydraulic leveling outriggers elevate the machine above flatbed truck height, allowing the truck to reverse directly underneath for 100% crane-free self-loading and unloading.
