¡ôThe double-pump and double-circuit open hydraulic system is adopted for concrete pump.The pump group and valve group equipped are world famous brand, Germany Rexroth and the hydraulic rubber hose is manufactured by Italian Manuli Rubber Industries S.P.A..
¡ôControllable full flow forced air-cooling radiator is applied to ensure the hydraulic system work under the best condition.
¡ôThe unique cone bottom hopper with 3D geometry optimized hopper design and double layer arc structure feature.The overall hopper is made of 16Mn thick steel plate , and it's wear resistance has been enhanced much more than the ordinary hopper.
¡ôThe adoption of wide flang, long stroke and large diameter for concrete cylinder, which ensures accurate assembly effectively. Under the condition of a certain delivery capacity, the times of stroke have been reduced greatly, thus the service life of the spectacle plate, the cutting ring, the piston and hydraulic components are significantly prolonged.
¡ôBy adopting American Haydon brand of linear stepping motor's automatic throttle controller, the control precision, reliability and service life are much more higher than other control mode. Thus, it not only realize energy-saving, but also thoroughly eliminate harsh conditions when the motor works with idle load at high speed for a long time.
¡ôThe photoelectric coupling non-contact control technology ensure longer service life and higher reliability than the relay control mode.

A¡¢Power System
The customer can free of choice main pump;
Use the universal acknowledged dynamical system-Swedish VOLVO generator and Germanic;
The power is strong and the fault rate is low. |

B¡¢Hydraulic Pressure System
The unique open-style hydraulic system and appropriate hydraulic cushion technology make the system work with less commutation force and heat. The heavy load hydraulic main pump with bigger volume and the hydraulic valve with wider pathway of world-famous brand guarantee concrete pump safety and reliability.
¡ôPrinciple of work:£ºThe pile-up valve group, the introduction of commutation cushion system in the return route of open-style hydraulic pressure, and use of the sensor examination commutation signal, can immediately carry on the automatic optimized control to the entire hydraulic system, thus facilitating the cushion effect for the system when the signal of sensor monitors is received by MCU/PLC..
¡ôThe high performance seamless steel pipes are selected for the hydraulic circuit. The excellent welding craft guarantees non-leakage of the pipeline. All pipe connections and the high-pressure hoses are of world-famous brand. Unique buckle tube technology is adopted to prevent occurrences of cartridge igniter and oil leakage.
¡ôThe high-pressure accumulator with large capacity and the cushion performance design with good condition make the swinging system more powerful, two times than the same type, thus reducing the requirement of tube S valve greatly for medium tong, and make low in construction work freely.

C¡¢Pump Stytem
¡ôThe design of the changeable diameter in the material mouth end of the pumping system can free the pressure of tong into the pipage to the largest degree, reduce the pressure loss of tube S and pressure concentration in the exit, and thus prolong the wear-resisting life of the exit of tube S. At the same time, the flange type connection between the pipe with changeable diameter and the exit can reduce the clash and tremor for the pump, and avoid the hidden danger brought by the clip type connection.
¡ôThe agitation system with large torque and agitation axis design easily knocked-down, can make it very convenient for customers to repair. The three built-up metal antifriction welding crafts in the agitation leaf blade can guarantee its longevity.

D¡¢Electric Control System
The humanized and intellectualized electric control system can optimize the human-machine interface and make the operation easy to handle.Intelligent control: It provides precise monitoring for the whole machine. The text displayer shows the working condition of the whole machine and keep timely warning. The optimized interlocking design effectively prevents accidents in operation. The setting of multi-protection mode in the control program like motor starter with electricity also prevents misoperation and enhances the reliability of the system.
