A brief introduction of concrete pump truck with boom

HONGDA concrete pump truck is developed by applying modern advanced computer simulation techniques and systematically analyzing what effect the change of such various parameters as stress,displacement,natural frequency,etc. pump truck structure receives has on boom’s fatigue life on HONGDA GROUP’s drawing on advanced experience both at home and abroad. Meantime, the group optimized hydraulic system’s design,adopted latest free fluid technique,greatly lessened pumping reversal’s impact on boom,and won many patents on pump truck boom structure’s optimization and hydraulic system’s design. Perfect product quality control,perfect product making,and absolutely adequate quality inspection make HONGDA pump truck achieve CHINA’s leading level and international advanced level. Pump system adopts steel plates all from SWEDISH SSAB, which have been treated by high-strength coldrolling with yield strength beyond 900Mpa, to ensure boom system with high-strength and light weight. The system’s aggregate carrying pipe,landing leg,and oil tank,etc. all have been treated by 100% stess removing after welding. Every welding seam has been treated by 100% nondestructive evaluation or X radial check to avoid any tiny defect and to make the machine more enduring.

The boom system adopts slewing bearing from GERMANY ROTHE ERDE or imported ITALY product, which have higher strength and longer using life with texture to be 42CrMo.

Accurate data support from finite element analysis and dynamics simulation analysis act as design basis to ensure boom system with a scientific structure and excellent property. Stess and strain test are conducted by national test center to verify the agreement between boom structure calculated analysis result and actual working condition.
