The sectional software of mechanical arm is optimized designed,with the help of simulation optimization to  attain a unity of strength and rigidity .And the inner sliding block material of telescopic arm is replaced from nylon to self-lubrication metallic material.

The electronic control system extracts main parameters in running state,monitoring real-time operation status,such as oil temperature,hydraulic pressure,filter element ,real-time pumping displacement ,cumulative volume ,accelerator admixture ,switch times and etc.

Dual-channel boom control system makes oil cylinder start flexibly ,improve the sensitivity of three nozzles and truly realize”spray anywhere you point out”.

Original pump is replaced by Danfoss pump to improve the reliability of the pumping system .Comprehensively upgrade the exit pressure level in the meantime to improve anti-blocking  capacity and adaptability to the materials.

Based on a lot of primary experimental comparisons , we optimized the design of concrete pumping pipe ; Adopting wear-resistant materials to casting bend pipe and reducer pipe and unequal thickness design method ,which greatly prolong the service life ; Besides , increasing pumping hose diameter to reduce friction resistance, more adaptable to the materials.
