Product Description

Large Diameter Crawler Type Air Track Drill Rig 350m Water Well Depth

The engineering behind the Large Diameter Crawler Type focuses on one goal: maximizing drilling productivity. The high-efficiency air compression system, combined with hydraulic top-drive rotation, achieves outstanding penetration rates in granite, limestone, and mixed formations. Its robust construction ensures years of trouble-free service with proper maintenance.

ST 350 Air Track Drill Rig

ST350 Air Track Drilling Machine is our best-selling product with an excellent reputation among customers. In real drilling tests, we achieved a depth of 325 meters with a 219mm diameter borehole, and we believe the final depth can reach 350 meters.

This drilling rig is multi-functional, with different configurations suitable for various geological conditions. All our water drilling rigs accept customization. Contact us with your requirements, and our engineers will help you get exactly what you need. The rig can also be mounted on a truck chassis.
