Wheeled towable chassis for flexible field transfer
The rig weighs 8 tons with dimensions of 4×1.9×2.3 m. The four-wheel off-road chassis can be towed, with optional hydraulic self-propulsion. Compact size fits standard container shipping for medium-deep drilling projects with scattered work sites.
High torque power head for soil and bedrock drilling
Max torque reaches 5900 N·m, main lifting capacity 18 tons and axial thrust 4 tons. It supports mud rotary and DTH hammer drilling, maximum depth 300 m and drilling diameter 105–300 mm, performing well in loose formations and weathered bedrock.
Dual drilling modes for wide formation adaptability
It can work with air compressor for DTH drilling or adopt mud circulation. Working air pressure ranges from 1.25–3.5 MPa and air consumption 16–55 m³/min. Two modes can be switched freely to improve drilling efficiency in rock layers.
Yuchai high-power diesel engine for continuous field work
Equipped with Yuchai 76KW diesel engine, it operates independently without external power supply. The penetration rate reaches 10–35 m/h, suitable for long-time continuous drilling in remote mountain and mining areas without electricity.
Modular standard design for convenient maintenance
It adopts recommended 76mm drill rods with 4m length. Most hydraulic spare parts are universally available. Optional accessories include mud pump, centrifugal pump and foam pump. Modular structure simplifies global maintenance.
Reliable hydraulic feeding system for controlled deep drilling
Max rotation speed: 85/170 r/min; auxiliary lifting capacity 1.2 tons, leg stroke 1.35 m. Four hydraulic outriggers stabilize the machine, reduce vibration and rod abrasion, and guarantee safe operation for 300m deep boreholes.

Self-supply water wells for mines and large pastures
It constructs independent water wells for mining camps and pastures. Powered by built-in 76KW diesel engine without grid electricity, it reaches 300m depth to provide stable domestic and production water for remote wild areas.
Deep irrigation wells for large agricultural bases
Designed for orchards and large breeding farms to drill medium-deep irrigation wells. It can pass through surface gravel and rock layers to obtain stable underground water, ensuring long-term water supply for large-scale agricultural development projects.
Deep drinking water wells for mountain rocky areas
It solves the shortage of shallow water in hilly mountain regions and drills water wells in weathered bedrock. Supporting DTH hammer drilling, the compact wheeled rig travels on narrow rural roads to secure drinking water for mountain villages.
Q1: What geological conditions is the ST300 drilling rig suitable for?
A1: It supports mud rotary drilling and DTH hammer drilling. It adapts to loose formations, sand, gravel and weathered bedrock. For intact dense granite, please contact us to confirm drilling feasibility before order.
Q2: What is the maximum drilling depth and main technical parameters?
A2: The maximum drilling depth is 300m, drilling diameter 105–300mm. Max torque reaches 5900 N·m with 18T main lifting capacity, powered by Yuchai 76KW diesel engine. Recommended drill rod size is 76mm, 4m per rod.
Q3: What is the difference between ST300 and ST200 water well rig?
A3: ST300 supports a maximum depth of 300m with larger torque and lifting force. It can drill into bedrock, targeting medium-deep rock water wells. ST200 is mainly designed for shallow soft formation projects within 200 meters.
Q4: Does the rig need external power supply during construction?
A4: It is equipped with Yuchai 76KW integrated diesel engine and works independently without grid power. Air compressor needs separate preparation when carrying out DTH hammer rock drilling.
Q5: Can I select optional accessories and customize configurations?
A5: Optional equipment includes mud pump, centrifugal pump and foam pump. Hydraulic self-propulsion can be upgraded. Please inform us of your target depth and geological conditions before placing orders.
