Operation speed further improved

Through the update and optimization of the hydraulic control system and the use of new large-capacity valves that reduce pressure loss, the cycle time has been shortened. Field operations can be performed more efficiently.

Adopt new large capacity control valve

The improvement of the control valve structure greatly reduces the pressure loss in the internal channel. The operating oil discharged from the pump is reasonably distributed and supplied to the actuator. In addition to individual operation, the operating speed during combined operation is also greatly improved.

Shortening of recirculation time and operability

The cumulative working time of the excavation dump bucket has been significantly improved compared with the current SH220LC-6. At the same time, when micro-operation is necessary, the control of operability is more superior, and large soil volume and operability coexist.

Improve hydraulic pump horsepower control and automatic digging force

The recirculation time is shortened, and the horsepower of the hydraulic pump is also increased during load-bearing excavation operations. In addition, when power is needed, the excavation force can be automatically increased, allowing the operator to feel the power output at will.
