PRODUCT DESCRIPTION

Characteristics

1: The Rugged track was driven by hydraulic motor with high traveling ability.

2: The feed and rotary head were driven by hydraulic motor, therefore, the air and oil consumption and total drilling cost are lower.

3: The hydraulic feed and rotary head put out the biggest feeding force and largest rotary torque, which makes it more suitable for operation in complex worksites.

4: The compressor equipped for the rig is smaller and cheaper than that one the air rig equipped, along with the best price-performance ratio than air rig.

5: The Hydraulic track oscillation makes it more suitable to drill in any rough terrain.

6: The carriage with rollers provides for minimal wear to the drill guide.

7: The Hydraulic auxiliary functions are easy and efficient for guide extension, boom swing, boom lift, guide tilt and guide dump.

8: The diesel engine and main hydraulic parts adopt imported products or famous domestic brand.

9: The special compensation device makes a full protection of drill rod threads.
