High operating efficiency. Due to the full hydraulic pressure and top drive rotary propulsion and lifting, it is suitable for various drilling techniques and various drilling tools. It is convenient and flexible in operation, fast in drilling speed and short in auxiliary time, so the operation efficiency is high.

low cost. Drilling on rocks is mainly based on the down-the-hole hammer drilling process. The down-the-hole hammer rock drilling operation has high efficiency and low drilling cost per meter.
