Truck-mounted concrete pump 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 boomï¿&frac*2;s fatigue life on HONGDA GROUPï¿&frac*2;s drawing on advanced experience both at home and abroad. Meantime, the group optimized hydraulic systemï¿&frac*2;s design,adopted latest free fluid technique,greatly lessened pumping reversalï¿&frac*2;s impact on boom,and won many patents on pump truck boom structureï¿&frac*2;s optimization and hydraulic systemï¿&frac*2;s design. Perfect product quality control,perfect product making,and absolutely adequate quality inspection make HONGDA pump truck achieve CHINAï¿&frac*2;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 **0Mpa, to ensure boom system with high-strength and light weight. The systemï¿&frac*2;s aggregate carrying pipe,landing leg,and oil tank,etc. all have been treated by **0% stess removing after welding. Every welding seam has been treated by **0% 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 *2CrMo. 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. welcome to contact me through email wangpinandy at yahoo dot com dot cn
