●  World innovation gradation III concrete pump (patent no: ZL200310110564.2) with max. grain diameter of aggregate of 80mm;
●  Unique double-mixing axle forced feeding mechanism (patent no: ZL02277347.9)with suction efficiency above 85%;
●  The self-developed high pressure ram-type distribution valve of the three-gradation concrete pump makes the pumping pressure reach 13MPa, which effectively solves the problem of pipe blocking;
●  The first to successfully develop three-gradation concrete mixing proportion and pumping construction process, which satisfies the requirements on pump ability of three-gradation concrete;
●  Energy-saving control technology of diesel engine saves oil consumption of more than 20%;
●  Full-hydraulic reversing open-type system provides for cleanliness of hydraulic liquid, low oil temperature and less reversing impulsion;
●  New functions like the infinitely variable control on the pump displacement, automatic switch between high and low pressure, auto-return control of concrete piston and hydraulic landing leg;
●  PLC control, real-time text display of working conditions ensures safe and reliable operation;
●  The main oil cylinder adopts proprietary technology of water-proof packing to effectively avoid emulsification of the hydraulic liquid;
●  Main hydraulic and electrical components are of well-known international brands with high reliability.
