Yuchai Excavator Digger 6 Ton Hydraulic Excavator

As an efficiency-oriented product featuring strong adaptation, green energy saving and excellent performance, the  hydraulic excavator is researched and developed on the basis of the market demands, with its the main pump pressure-flow (P-Q) curve optimized to improve the working efficiency and reduce fuel consumption.

Its newly-updated main control valve can achieve better coordination of the executive components and smaller loss of the flow pressure. It adopts a new controller as well as upgraded processor hardware with the calculation speed increased by 20%, able to greatly improve the response time of negative flow power regulation.

Reasonable setting of the adjustment parameters can exclude the gas-guzzling working area of the engine, make more sufficient and reasonable use of the engine power, perfect the matching of the pump and the engine, and thus achieve high efficiency and energy saving.
