    Boom pump truck howo30m

    Short Description:

    1.EquipΦ230mm cylinder, large displacement pumping system, the material absorption is more than 88%, the number of commutation with the same displacement is low, and the wearing parts life is long;

    2.The pumping system adopts electronically controlled commutation. The pumping commutation is quick and accurate, for system impact is small, and the actual pumping efficiency is increased by more than 7% over the conventional hydraulically controlled commutation system.

    3.Adopts industrial large pump truck integrated valve, the line is simple, the pressure loss is small, compared to the conventional valve energy saving 17%. Hydraulic systems are not prone to heat.

    CO-NELE concrete pump truck structure receives has on boom’s fatigue life on CO-NELE’s drawing on advanced experience both at home and abroad. Meantime, the company optimized hydraulic system’s design, adopted latest free fluid technique, greatly lessened pumping reversal’s impact on boom,and won many patents on concrete pump truck structure’s optimization and hydraulic system’s design. Perfect product quality control, perfect product making, and absolutely adequate quality inspection make CO-NELE 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.
