It can be operated in all terrains and complex working conditions, and the meteorological weathered rock, strong weathered rock, cobblestone, backfill stone, etc. can be taken by one machine
This rotary drilling rig is equipped with a machine lock drill rod. The maximum drilling depth can reach 68m, the drilling diameter is 600-2400mm, the maximum torque of the power head is 285KN.m. The high-power turbocharged medium-air cooling engine is equipped, and the power system is more efficient 3. Higher transmission efficiency.The H-type retractable crawler chassis can overcome various complicated construction road conditions. The chassis telescopic function can improve the center of gravity of the body of the pile driver construction operation and increase its stability. The rig is equipped with a new generation of humanized cockpit, a new human-machine interaction interface, a new control system, 360° full-angle monitoring, and can be controlled by wireless remote control to achieve driving steering, chassis expansion, body rotation, mast lifting and other functions.
