LQ-400 positive circulation drilling rig

The LQ-400 positive circulation drilling rig is an impact rotary drilling rig, and its internal structure is different from that of a general rock drill. Its air distribution and piston reciprocating mechanism are independent, namely the impactor Its front end is directly connected to the drill bit, and its rear end is connected to the drill rod By combining the advantages of various similar types of machinery, we have achieved high efficiency, easy disassembly, light weight, and easy transfer in our work. With excellent quality, we have gone through several glorious years The main technical parameters of this product (LQ-400 positive circulation drilling rig) are as follows: maximum drilling depth: 400m, maximum drilling diameter: 300mm, drill rod length: 2000mm-3000mm, maximum stroke of power head: 4600mm, drill rod diameter: 89mm/108mm/114mm, lifting force: 30T, turning torque: 10000NM, bearing method: hydraulic track type, walking speed: 3000km/h, climbing ability: 30 °, external dimensions: 3550mm * 1600mm * 2550mm, total weight of the machine: 8000kg
