Product Introdction
The HY350 350m crawler water well drilling rig is a heavy‑duty deep‑well drill rig built for complex terrain and demanding deep borehole projects. In addition to robust mechanical structure, it is fitted with a high‑torque top‑head rotary drive and dual‑purpose drilling system. This versatile hydraulic rig performs reliably for deep water wells, geothermal heat pump installations and geological survey drilling.
It achieves a maximum drilling depth of 350 m and bore diameter up to 350 mm. Meanwhile, supporting both mud pump and air compressor dual‑mode drilling, the HY350 handles soil, sand and hard‑rock formations under challenging geological conditions.
Furthermore, its heavy‑duty crawler chassis enables smooth travel across uneven and muddy job sites. The advanced full‑hydraulic control system delivers precise operation and stable rotary output for extended field work.


Complete safety features include emergency stop buttons, automatic locking systems and high‑pressure safety pipelines to protect operators and work sites. Besides, it boasts a user‑friendly control interface; the HY350 is simple to operate even for less‑experienced personnel, cutting complex procedures and lowering on‑site labor costs.
Apart from reliable performance, thanks to outstanding durability, strong terrain adaptability, dependable hydraulics and full safety design, the HY350 350m crawler water well drilling rig is a trusted choice for global drilling contractors and geothermal engineering teams. This heavy‑duty well‑drilling equipment works efficiently for rock water well projects across diverse field environments.
