Product Overview
This tractor-mounted pneumatic water well drilling rig is designed for high-efficiency drilling in complex geological conditions, especially in mountainous areas, hard rock layers, gravel, and cobble formations.
By combining air DTH hammer drilling and rotary water drilling, this machine overcomes the limitations of traditional rotary rigs in hard rock and the inefficiency of air hammer drilling in soil layers.- a common challenge discussed in 【Air Drilling Vs Water Drilling: How To Choose The Right Method For Hard Rock And Mixed Formations】 when selecting drilling methods for complex formations.
In real field operations, its drilling efficiency can reach up to 10 times that of conventional rotary drilling rigs, significantly reducing drilling time and overall project cost.
It is an ideal solution for users seeking fast penetration, stable operation, and low operating cost in water well and irrigation projects.
Applications
This video demonstrates the actual operation of this tractor-mounted pneumatic water well drilling rig.
Deep water well drilling
Agricultural irrigation wells
Geothermal heat pump boreholes
Mountain water extraction projects
Hard rock, gravel, and cobble layer drilling
Especially suitable for areas where traditional rotary drilling struggles and air DTH hammer drilling fails in soil layers.
Advantages
Competitive advantage
The company conducted a competitive advantage analysis to identify its strengths and weaknesses compared to its rivals.
1. Mechanical Main Drive with Hydraulic Assistance
The rig adopts a mechanically driven main system, with hydraulic power used only where necessary.
This design effectively reduces power loss, lowers fuel consumption, and significantly cuts drilling costs.
01
2. Wide Speed Range & High Torque Output
- Multiple forward speed stages
- Speed range: 14–500 rpm
- Output torque: 250–13,428 N·m
This allows operators to easily adjust drilling parameters for soft soil, hard rock, and mixed formations.
02
3. Dual Reverse Speed for Emergency Handling
Equipped with two reverse gears, making it easier to handle stuck drill tools, collapse situations, or unexpected underground conditions.
03
4. Long-Stroke Dual-Speed Power Head
- Power head stroke: 3800 mm
- Long stroke design reduces:
- Frequent rod handling
- Drill pipe blockage
- Burning and abnormal wear
This directly improves drilling efficiency and operational safety.

5. Dual Oil Pump Hydraulic System
- Single pump during drilling
- Dual pump flow merging during lifting and lowering
This intelligent system minimizes power loss, shortens auxiliary operation time, and improves overall working efficiency.
05
6. User-Friendly Structure & Easy Maintenance
Advanced structural layout with:
- Clear component positioning
- Easy access for inspection and maintenance
- Lower long-term service costs
Ideal for overseas users and field maintenance conditions.
06
7. Crawler Chassis with Long-Stroke Outriggers
- Crawler-mounted chassis for strong terrain adaptability
- Outrigger cylinder stroke: 1.5 m
- Automatic loading for easier transportation
Stable operation even on slopes and uneven ground.
