Caterpillar Type Drilling Machine

The mast's top side adopts frame structure, which has strong bending and compressive resistance capacity. So this ensures the stability of whole machine and the rigidity of the mast, and the completion of the construction under different geological conditions. Its diesel has automatic acceleration/deceleration function and makes the fuel consumption descend by5-10 percent. Representing the advanced technology of the drilling machine, Caterpillar Type Drilling Machine is applicable to extremely large and deep construction.
