1. Introduction of ST-400 mud/air drilling rigST-400 mud/air drilling rig is a water well drilling rig that mix mud drilling rig and air drilling rig in one equipment with mechanical top head. It is a good solution to the difficulty of drilling in the soil layer for DTH rig and the low efficiency of drilling for mud rotary rig in the hard rock, gravel and pebble layer. The mud/air drilling rig adapts to various soil strata. The mud/air drilling rig is efficiency and energy saving to drill water well and

FL series bore well drilling machine is a type of light, high efficient and multifunctional drilling rig. It is widely applied in water well, irrigation well or other boreholes, especially good for mountain areas or rock foundations. The drilling rig adopts new hydraulic technology, supporting high-torque hydraulic motor rotation and large-bore hydraulic cylinder propulsion.

All drilling rigs here are multifunctional, it can be used with air compressor, mud pump, even we can just use the dry hydraulic drilling method.The drilling rigs are not only designed for water drilling. They can be used in all conditions based on pore-forming purpose.They are widely used in industrial and agriculture water project, testing well and other exploration borehole. In particular, drilling hole for geothermal heating, it can also meet the engineering basis for reinforcement, loose gravel drilling rock formation connected with a variety of engineering.Our drilling
