Large Torque Rotary Drilling Rig Successfully Developed

The first large-torque rotary drilling rig in China was successfully developed and put into production at Shijiazhuang Coal Machinery Company.
Rotary drilling rigs are foundation hole drilling machines commonly used in developed countries today, and are widely used in roads, railways, bridges, urban transportation, and high-rise building pile holes. At present, the equipment mainly relies on imports. The XZ-20 rotary drilling rig produced by Shijiazhuang Coal Mining Machinery Company introduces advanced technology from Finland. The maximum drilling diameter is 2 meters, the maximum depth is 60 meters, and the maximum torque is 20 tons per meter. The machine adopts an extended crawler chassis, self-rising folding mast, free vertical adjustment of drilling, hole depth automatic display, touch screen and monitor at any time to display the working status and other advanced operation control system, with large torque, low noise, high drilling efficiency, With flexible and convenient operation, safe and reliable operation, and compliance with environmental protection construction requirements, the product fills the gap in the domestic rotary drilling rig market.
