DMD350/350L Mechanical Top Drive Drilling Rig for Water Drilling and Air Drilling

DMD-350/35OL mechanical top drive drilling rig is a drilling equipment independently developed by the company that can drill 90° and integrates the functions of water drill and air drill (National Invention Patent: ZL201510479602.4). It adopts 5-speed manual car transmission wide speed range, sensitive and convenient forward and reverse switching. high transmission efficiency, greatly reduced power energy consumption, more efficient and energy-saving. t solves the difficulty of drilling with air down-the-hole hammers in soil layers and the low construction efficiency of rotary drilling rigs in hard rock layers. gravel, and pebble layers.
