MKDQZ-350 Pneumatic Water Well Drilling Rig
Overview
The MKDQZ-350 is a cost-effective crawler-mounted pneumatic water well drilling rig designed for medium-shallow borehole construction. Powered by a 91kW Yuchai diesel engine and adopting mature DTH (Down-the-Hole) air percussion drilling technology, it delivers steady and efficient rock-breaking performance across formations from soft soil and sand-gravel layers to hard granite and limestone. With a maximum drilling depth of 350m and a bore diameter range of 140–325mm, this rig is ideally suited for rural domestic water supply, agricultural irrigation wells, foundation dewatering and small-scale geothermal drilling projects.

Key Features
1. 350m Max Drilling Depth with 140–325mm Wide Bore Compatibility
This pneumatic drill rig supports a maximum drilling depth of 350 meters and adapts to borehole diameters from 140mm to 325mm, fully covering the construction needs of most residential water wells, farm irrigation wells and small industrial water projects. One unit can undertake both small-diameter deep water wells and large-diameter shallow dewatering holes, eliminating extra equipment investment for different project types.2. 91kW Yuchai Diesel Engine with Fuel-Efficient Reliability
Equipped with an original 91kW Yuchai diesel engine — a globally recognized power brand with worldwide after-sales support and readily available spare parts — this rig features sufficient power reserve, low fuel consumption and high durability. It maintains stable output even in high-altitude, high-temperature and dusty field environments, effectively reducing unplanned downtime and long-term operation costs.3. 30° Max Climbing Crawler Chassis for All-Terrain Mobility
The reinforced steel crawler chassis has a maximum climbing capacity of 30° and a travel speed of 2.5km/h. It features excellent off-road passability and can easily reach mountain slopes, hilly areas, muddy farmland and other construction sites inaccessible to truck-mounted rigs, realizing flexible transfer between adjacent well positions without additional hoisting equipment.4. 15–35m/h High Penetration Rate for Hard Rock Formations
Leveraging DTH (Down-the-Hole) pneumatic percussion drilling principle, the rig achieves a penetration efficiency of 15–35m/h in typical hard rock strata. Compared with traditional mud rotary drilling rigs, it dramatically improves rock-breaking speed in dense geological conditions, significantly shortens single-well construction cycles, and allows drilling teams to complete more projects within the same operating period.
5. Multi-Spec Drill Pipe Compatibility for Flexible Project Configuration
The rig is compatible with Φ89mm and Φ102mm diameter drill pipes, and supports length options of 1.5m, 2.0m, 3.0m and 6.0m. Users can flexibly match drill pipe solutions according to well depth, bore size and geological conditions, avoiding extra procurement costs for additional drilling tools and improving equipment adaptability to different projects.6. 22T Strong Axial Lifting Force for Safe Deep Hole Operations
The main hoisting system delivers up to 22 tons of axial pulling force, which can smoothly lift the full drill string from 350m deep boreholes and effectively handle pipe sticking and other downhole emergencies. The robust lifting capacity ensures safe and efficient tripping operations, lowers on-site safety risks for construction crews, and extends the service life of drilling tools.Get a quote
