SH520 excavator adopts Linde hydraulic system, which is not only an external upgrade, but also an internal function upgrade of the machine. Due to the customized load sensing system, the fuel consumption per hour is further reduced, and the work efficiency and fuel efficiency are greatly improved. In the corresponding application, three working modes can be optimized and matched, thus saving energy and improving work efficiency.
