Skid-based full hydraulic rotary percussion drill 'Aroad Drill' series compatible with 3.5m liners.
We have enhanced the popular RPD-75SL-H2. The hydraulic rod clamp has been changed to a free type, addressing oil leaks from the conventional cylinder section, unifying the pieces (P57 to P146), and enabling compatibility with rod wear-related slipping. Additionally, in addition to movement using traveling rollers with single pipes, we have equipped the main machine's slide base with a jack cylinder, allowing lateral movement even without single pipes.
