- Robust Dongfeng Core: Built on a chassis known for high torque and durability, ensuring steady PTO (Power Take-Off) for the hydraulic system during long work shifts.
- Compact Transport Mode: The folding boom retracts into a compact footprint, allowing the truck to travel through low tunnels and narrow streets with ease.
- Synchronized Safety Controls: Features real-time interlock systems between the stabilizers and the boom, preventing accidental tipping or structural stress.
- Enhanced ROI for Contractors: Its versatility means it can handle jobs that straight-boom trucks cannot, opening up more revenue streams for rental and maintenance fleets.
