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; As the inclined-mounted slide valve is adopted as the distribution valve, the capacity of material-suction is good, and the work is reliable; 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; The text display with large screen which is operated in menu type could lessen operation buttons; and the protection level of the electric control box reaches Grade-IP65; 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.
