This 33-meter pump truck is a multi-functional construction powerhouse, equipped with a 270-horsepower powerful engine, a 4.7-meter short wheelbase, and a high-power generator and a 700-compulsory double horizontal shaft mixer, ensuring efficient and rapid concrete mixing. The 90 pump system makes the concrete delivery smoother and more efficient. This pump truck performs well on narrow rural roads and in the construction of 3-5 story buildings, making it an ideal choice for construction projects. The intelligent control system of this pump truck enables the entire process from raw material proportioning to mixing and high-pressure pumping to be precise and error-free, ensuring the rapid and stable pouring of concrete.
