DMD500/500L Mechanical Top Drive Drilling Rig for Water Drilling and Air Drilling

DMD-500/500L mechanical top drive drilling rig is a drilling equipment independently developed by the company that 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. It 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.
