Drilling products produce tunnel drilling rigs for coal mines, hydraulic drilling rigs, meter drilling rigs, meter drilling rigs, and are the first drilling rig company in Hebei. It is a product of our Hebei Shijiazhuang coal mining machine and is also the birthplace of drilling rigs.
The series of drilling rigs are mainly composed of power head gearbox, drawworks, brake, brake, chassis, console, drilling tools and other parts. According to the on-site use requirements of Fengcheng Mining Bureau, the partial design of the drilling rig has been improved, and the drawworks components can be eliminated. The drill pipe equipped with the drilling rig is made of alloy steel, and the welding process uses special equipment to weld face to face with friction hot melt. It has excellent quality and high strength. The casting shell mold was changed from a log mold to a metal mold, which fully ensures the interchangeability of the main components of the drilling rig and improves the quality of the drilling rig.
