RC Reverse Circulation Drilling Rig Heavy Duty Machinery for Soil Gold Mining and DTH Drilling Projects

Product Description

High-efficiency drilling rig hoist

Equipped with a high-performance hydraulic power motor, it features powerful output, precise speed control, safety and reliability, as well as simple operation and easy maintenance.

Fully hydraulic centralized control console

The fully hydraulic centralized control is convenient and flexible

The rotational speed, torque, thrust shaft pressure, reverse shaft pressure, thrust speed and lifting speed of the drilling rig can be adjusted at any time to meet the requirements of different drilling tool usage conditions and different construction techniques.

Double hydraulic power head

 

The hydraulic dual power head offers strong power and a significant increase in torque output. Whether in hard rock layers or complex geological structures, it can precisely drill holes, handle them with ease, and the drilling efficiency will increase sharply.

Top-drive rotary propulsion lifting

Top drive power head has anti-impact design patented technology, rotary gear reducer reliable and durable, direct access to the drill pipe, shorten the auxiliary time, but also conducive to pipe drilling.
