Which Buyers Need This Category?
Deeper Water Well Contractors
For buyers who need more than compact 100m or 150m machines, large crawler rigs provide stronger lifting, feed control and drilling package flexibility.
Hard Rock and DTH Projects
When the formation includes hard rock, the rig must be matched with air compressor, DTH hammer, bit diameter and air pressure, not only drilling depth.
Rough or Unpaved Jobsites
Crawler chassis helps the rig move and stabilize on unpaved roads, construction sites, rural projects and uneven drilling pads.
Technical Positioning
Large Water Well Drilling Rig Selection Factors
| Factor | What to Confirm |
|---|---|
| Water Well Depth Class | Confirm whether the well project is 200m, 300m, 400m, 500m or 600m class. Depth must match rig pullback, drill pipe, mud pump or compressor package. |
| Drilling Method | Choose mud circulation drilling, DTH air drilling or combined method according to soil, gravel, weathered rock and hard rock. |
| Chassis | Large crawler chassis is suitable for rough jobsites, unpaved access, rural water projects and contractor mobility. |
| Power and Torque | Torque, feed force, lifting capacity and engine power must be checked together, especially for hard rock and larger boreholes. |
| Export Package | Confirm transport size, spare parts, rods, hammer, bits, mud pump, compressor recommendation and local service conditions. |

FAQ
Hydraulic Drilling Rig FAQ
Is this category for small drilling machines?
No. This category focuses on larger water well drilling rigs for 200m to 600m class projects, not compact light drilling machines.
Can these rigs drill hard rock?
Hard rock drilling depends on the complete package: rig torque, feed force, air compressor, DTH hammer, bit size and operator setup.
Why list LY-280 and LYXY-3 first?
Both models now have confirmed parameters and product images. More 200m-600m rigs should be added only after official names, specifications and photos are ready.
Can LIYO recommend a 400m or 600m water well configuration?
Yes. Send the target well depth, borehole diameter, ground condition and country. LIYO can recommend the correct model and drilling package after confirming project requirements.
Need a 200m-600m Crawler Water Well Drilling Rig?
Send well depth, borehole diameter, ground formation, country and drilling method. LIYO Machinery will recommend a practical crawler water well rig configuration for your project.
