SDL-280/XSDL-280 mechanical top drive drilling rig
SDL-280/XSDL-280 mechanical top drive drilling rig is a kind of drilling equipment independently developed by the company that integrates the functions of water dilling and air drilling. The drilling rig adopts a 5-speed manual automobile gearbox and a mechanical top drive power head. It has a wide speed range, convenient forward and reverse switching, high mechanical transmission efficiency, and greatly reduced power energy consumption. It is more efficient and energy-saving, which solves the problems of difficult air DTH hammer drilling in soil layers and low construction efficiency of rotary drilling rigs in hard rock layers, gravel and pebble layers.
