The fourth generation ROADS intelligent control system is matched with a large flow pump and valve,with a rotary drive that balances high torque and high speed,making it easy to shake soil and achieving higher construction efficiency;
The entire machine can be transported with the Kelly bar attached,allowing a single flatbed truck to complete the transfer.This enables rapid switching between work and relocation,saving 4 hours and reducing costs by 30%in a single disassembly and assembly process;
 
        Optimize product detail design:pipeline optimization design,single row layout of mast pipeline,for a more concise appearance;
Equipped with a one-click automatic mast raising and lowering feature,reducing operator fatigue;
One click soil throwing,automatic rock entry,one click inverted mast,one click upright mast.
