Euro 3, Euro 5 and Euro 6 common-rail electronic versions meet high-level environmental-protection requirements with fuel-saving and eco-friendly performance.
Q5: What working conditions is each horsepower version suitable for?
371HP(Euro2, selected markets only) for short-haul concrete delivery at medium-small construction sites; 400HP(Euro3/Euro5/Euro6) for medium-distance concrete transportation; 430HP(Euro3/Euro5/Euro6) high-torque version for high-intensity field construction-site operation on mountainous and steep-slope roads. HW25712XSTL 12-speed gearbox is recommended for 430HP under heavy-load climbing conditions.
Q6: What are the core advantages of this model?
