One SANY SR220C rotary drilling rig was used for digging piles in Port Said of Egypt. In spite of the viscid earth of this region, the piles must reach 60m deep. And finally, the SANY rotary drilling rig has successfully accomplished the work with high efficiency and low cost.
Based on the flush-type system, SANY rotary drilling rig has a core work mechanism controller and perfect CAN-BUS technique. Its powerful output torque, stable performance and high efficiency are highly praised by its user, MISR RAYMOND FOUNDATIONS.
