Product Overview
This drilling rig operates in conjunction with a pneumatic power unit. A pneumatic distribution valve controls the pneumatic motor, which drives the drill string to rotate.
The pneumatic top-drive drilling rig comprises a rotary table, a pneumatic motor, a directional control valve, and a rotating assembly.
The new‑type power head features a separate circulation system for drilling fluid and bearing housing, reducing the likelihood of bearing failure. The clearance between seals is adjustable, resulting in extended maintenance intervals.
Application scenarios: blasting holes, seismic exploration shot holes
Advantages: lightweight, easy to operate, faster, and cost-effective.
