SX 30 Double Cutter Drilling Rig

Adopting Hagglund CA210 motor drive, SX 30 double cutter drilling rig has its cutters connected with the frame, and the frame is connected with the main winch through steel rope and lifting pulley. The type of the base machine is SG60, which is equipped with double tubing winch, discharge tubing winch, compressed air pipe winch, pressure retaining oil tank. Linked with the frame and driven by the oil cylinder, the cutter head can move forward and backward, and rock debris cut by it will be discharged by suck slag tube through air lifting. In addition, the alignment cylinder on the frame can guarantee the verticality of the slot milling.
