? Hydraulic system adopts imported factory-assembled valve groups to control concrete pump with much higher reliability; ? Main electrical components, all imported factory-assembled, fully ensure high reliability of electrical control system; ? Distribution valve applies advanced S valve and slide valve system with good seal performance, simple and reliable structure, and convenient replacement of wearing parts; ? The main oil pump with constant-power variable large delivery volume has high efficiency of main power under constant power; ? Blade, especially designed with little dead angle of agitation, can be fit for many kinds of concrete mix proportions; ? Due to its functions of automatic recession, the check and change of piston heads will be convenient and rapid; ? Especially designed hopper, with independent intellectual property rights, having little dead angle of agitation and small accumulated materials, could be cleaned easily; ? The text display with large screen which is operated in menu type could lessen operation buttons; ? The speed adjustment of the diesel engine automatically controlled by computers had gained the domestically exclusive patents; ? As the electro proportional controlling technology is introduced, the pumping displacement could be adjusted steplessly; ? With good maintainability, the assembly and disassembly of all wearing parts is very convenient.
