The customer requests our company to develop a multi-way valve to achieve high-frequency shaking function for the bucket.

Due to the loader bucket itself not having the ability to remove clay, it easily accumulates soil when operating in wetlands or mountainous areas. When the accumulated soil reaches a certain thickness, it affects the work and can only be manually removed. Manual removal of soil is often time-consuming and leads to low work efficiency.

With the increasing demand for operational comfort, the proportion of loaders adopting hydraulic pilot control unit has been increasing year by year. When users need it, they can quickly operate the pilot handle, and the multi-way valve responds promptly, controlling the reciprocating extension of the piston in the tipping cylinder, causing the bucket to vibrate and achieve the shaking function of the loader. So, how can we achieve timely response of the multi-way valve when operating the handle at high frequency without compromising its performance?

This is the core and difficulty of technical improvement. It requires adjusting the area of the throttle slot within the range of the multi-way valve's spool stroke to achieve rapid pressure buildup in the system and realize the shaking function. But where is the optimal adjustment point?

To address the "shaking material" issue, our experienced technical engineer Zhou Jian and his colleagues got busy. Zhou Jian, who has worked diligently in the technical development department for 14 years, is well-known for his seriousness, meticulousness, and precision. Discussions on working conditions, analysis of principles, brainstorming, manufacturing trials, performance testing... It took two weeks before the first installation test began. At XCMG's technical center, everyone held their breath and closely observed the testing process: the impact force was insufficient, and the shaking function was not obvious.
After continuous analysis, design, trial production, and testing, one month later at XCMG, the team from the technical center, quality department, and after-sales service department conducted an installation test together, and the shaking effect was significantly improved.
However, meticulous Zhou Jian noticed that there were two or three instances of instability during hundreds of consecutive shaking operations. Zhou Jian and the XCMG technical staff unanimously decided to continue improving until the customers were truly satisfied.
After the third round of improvements came the third round of testing. At XCMG's testing field, the customers watched the entire testing process and finally gave their thumbs up, praising, "The impact force is very significant, and the shaking is quick and clean. It's exactly what we wanted!"
The improvement in shaking performance reduces the labor intensity of manual cleaning, shortens cleaning time, and improves work efficiency.

The success of this technical breakthrough has significantly enhanced the market competitiveness of loaders, as the multi-way valve is now applied in lifting operations, material spreading, and other working conditions, with obvious effects.

After three and a half months of collaboration between Gaoyu and XCMG Group, we have solved their problem and achieved long-term cooperation!
