Described here is our DZ-350 DTH water well drilling rig that is a light weight, efficient and multi-functional crawler mounted drilling rig.
1. This DTH drill rig is mainly used for drilling of water well and monitoring well, geothermal drilling and other drilling applications.
2. It is able to conduct compressed air operated down-the-hole drilling in numerous kinds of formations.
3. Mast folding up and down, rotation head going up and down, drill pipe loading and unloading, rotating and drilling, hoisting, traveling and other movements are driven hydraulically, considerably reducing labor intensity and improving drilling efficiency and quality.
