Shantui paver improves the material conveyance and distribution capability to meet the 50cm thick paving need and increase the theoretical productivity. The large-diameter large spiral blades are used and the material feeding passage is optimized to mitigate the material segregation and improve the road construction quality while guaranteeing the efficient and stable materials supply. Four paver models are designed with one same platform. Featuring high-end configuration, high driving/riding comfort, convenient maintenances, and high reliability and cost-performance, they boast excellent paving stability.
