Advantages

1. The crawler leveling device makes the center of gravity more stable and the crawler adhesion stronger.The protection design of braze bin and cab can eliminate the hidden danger of personnel safety.

2. The drilling rig can excavate multiple rock holes at one time with its flexible drilling arm and off-road function, which can meet the drilling requirements of various primitive landforms.

3. Equipped with high frequency hydraulic drill, the unit energy consumption of drilling rig is unmatched competitiveness.
