Product Highlights
High-Performance Kawasaki Hydraulic Pump System: Equipped with a Kawasaki main oil pump delivering strong hydraulic power up to 28MPa, ensuring stable concrete conveying, reduced pipeline blockage risk, and a longer component service life for long-distance underground transportation.
Diesel-Electric Dual Power System: Features a flexible diesel-electric dual power design allowing self-propelled movement and strong climbing ability on-site via diesel power, followed by a switch to electric power for low-emission, cost-effective shotcrete operation.
S-Tube Valve Pumping Technology: Utilizes a heavy-duty S-tube valve structure designed for engineering concrete containing coarse aggregates up to 15mm, providing smoother concrete flow and improved continuous spraying performance compared to traditional ball valves.
Precision Accelerator Dosing System: Combines a variable-frequency accelerator dosing pump with compressed air atomization technology for continuous dosage adjustment, ensuring precise chemical mixing, a lower rebound rate, and better concrete adhesion.
