Product Features
This through-hole drilling rig is equipped with a high-pressure hydraulic system and variable displacement piston pump, providing strong and stable power with load-adaptive performance, ensuring stable and effcient drilling without power loss, deviation or jamming in deep holes.
Featuring one-key continuously variable transmission, it is easy to operate and highly adaptable to complex formations including hard rock, fractured zones, cobble beds and silt layers.
With intelligent fuel saving, high reliability and low failure rate, it greatly reduces overall operating costs.Its through-hole structure ensures smooth coring, casing and cable running, and its key performance is comparable to international frstclass brands, making it the ideal choice for deep-hole and complex formation projects.
