Our concrete pump truck is developed by applying modern advanced computer simulation techniques and analyzing systematically what effect the change of such various parameters as stress,displacement,natural frequency,etc. And it optimized hydraulic system's design,adopted latest free fluid technique,greatly lessened pumping reversal's impact on boom. Perfect product quality control,product making and quality inspection. Accurate data support from finite element analysis and dynamics simulation analysis act as the design basis to ensure boom system with a scientific structure and excellent property.
