Shanbo SR220 excavator uses the method of three-dimensional structure design and finite element analysis to simulate and analyze the load on the car body and realize a reasonable high-strength structure. High-strength left and right platforms, thickened and high-rigidity turntable ensure strong excavation and high-speed driving.

And the international advanced hydraulic system is adopted. By setting the action priority and optimizing the system throttling, the operability is better and the action is more accurate. When the boom is lifted and the bucket is dug, the hydraulic oil is fused in the valve to improve the working efficiency; The stick has the function of regeneration, which accelerates the running speed of the stick. Compared with the traditional model, the system pressure is improved.

Compared with the traditional way, the system pressure increases and the mining force increases by 11%.

The optimization of the internal passage of the main valve reduces the pressure loss during the internal transmission of the system, and comprehensively saves oil by 5%-8%.
