Rotary Drilling Rig SR200C
Rotary Drilling Rig SR200C uses truss type mast. Under the effect of pressure, it has strong bending, compression resistance capabilities, which ensure the stability of the whole machine and the rigidity of the mast. Its diesel has automatic acceleration/deceleration functions and makes the fuel consumption descend by 5-10 percent. Rotary drilling rig is applicable to the fundamental construction of the railways, highways, bridges etc.
