Wear Resistant Long Lifespan Air Hard Rock Drilling Rig for Mountain Drilling
mountain rock drilling rig
,mountain water well drilling rig
,hard rock rock drilling rig
The engineering behind the OEM 350 Meters 140kw 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.
ST350 series is mainly applied in drilling wells, irrigation wells, geothermal wells and air holes for other purposes, especially for mountain and rock formation water engineering. The water well drilling rig machine can work on different formations, well drilling diameter up to 350mm. The drill machine adopts new hydraulic technology, supporting high torque hydraulic motor rotation and big bore drill hydraulic propulsion, branded multi-cylinder engine-powered two-stage air filter and the intake air compressor designed for hydraulic systems.
