Product Overview
The HD-C20A crawler-mounted drilling rig is a fully hydraulic drill mounted on a specially designed mechanical transmission‑driven tracked chassis. It is suitable for drilling operations in challenging terrains such as beaches, farmland, river networks, marshes, grasslands, and muddy areas, supporting seismic exploration and mineral‑field investigations.
The dual-speed power head can meet the varying requirements of mud drilling, rotary‑drilling, and air‑drilling/air‑percussion drilling for either high torque or high rotational speed. The standard dual‑speed power head equipped on this rig is interchangeable with the company’s dedicated air‑drilling power head.
