1，By using the load-sensitive technology, the pressure distribution of
the whole system is more reasonable, no throttle loss. The system
conversion efficiency is high, and more energy saving and environmen-
2，The power head with mechanical spring and cone block clamping /
hydraulic release mode, clamps reliably for long maintenance cycle.
3，The feed system is driven directly by the cylinder, so the structure is
simple and compact, and the feeding / pulling force is bigger.
4，Standard hydraulic base who can achieve 0-180 ° tilt adjustment,
convenient , fast and reliable.
5，With a hydraulic winch for taking the core.
6，Ergonomic console can achieve centralized control and drilling
parameters show . The operation is convenient,
safe and reliable under low labor intensity.
