Horizontal directional drilling rig system configuration

Drilling rig system: it is the main body of drilling operation and backdragging operation of crossing equipment. It is composed of drilling rig host, turntable, etc. The main rig is placed on the rig frame to complete drilling and towing operations. The rotary table is installed at the front end of the main machine of the drilling rig and connected with the drill pipe. By changing the turntable steering, output speed and torque, it can meet the requirements of different working conditions.
