Product Description

Product Description
The mechanical top drive series drilling rig is a water well drilling equipment independently developed by the company that integrates the functions of water drilling and air drilling. It adopts a 525 gearbox for vehicles, which has a transmission efficiency doubled compared with hydraulic transmission and reduces power consumption by 35%, making it more efficient and energy-saving. It solves the problem of the difficulty of air down-the-hole hammer drilling in soil layers and the low construction efficiency of rotary drilling rigs in hard rock layers, gravel and pebble layers.
