product Introduction

1. Cab Spacious, wide field of vision, humanized cab, emphasizing safety performance, front window protective fence.

2. Double motor swivel head Cycloidal hydraulic dual-motor slewing head with high output torque and extremely low failure rate.

3. Disc automatic rod changer The disc automatic rod changer allows free selection of drill rods to extend the life of the drill tool. The patented floating hose reel eliminates the concentrated point of tubing deformation and prolongs the service life.

4. Advance beam The cylinder is driven by steel wire rope, the propulsion force is controlled with high precision, and the rotary head runs smoothly It can drill various intermediate angle holes and horizontal sole holes.

5. Dust removal device Chigo's two-stage dust removal technology leads the industry. Dust removal and cleaning filter area is large, automatic continuous self-cleaning dust removal. The dust filter element array can be easily disassembled, and the maintenance efficiency is high; The integrated cover can slide up and down to clearly observe the opening situation and perform opening control.

6. Strong traction Tracked heavy-duty chassis, track frame hydraulic swing device swing frame ±10°; Great traction, enough off-road ability to improve the efficiency of the special field.
