Under high-load conditions, power output remains stable without fatigue or speed drop. The power system has undergone professional fuel-saving tuning, resulting in low operating vibration and noise, and excellent fuel economy. It supports long-term, all-weather continuous construction, effectively reducing daily energy costs and meeting the high-frequency, routine construction needs of construction teams and individual users.

The machine is equipped with an upgraded closed-loop hydraulic control system, resulting in greater hydraulic flow, faster response, and more even power transmission. The entire set of operating actions—digging, lifting, rotating, lowering the blade, and bulldozing—is seamless, linear, and without jamming, vibration, or lag. The equipment's digging depth, digging force, and rotating efficiency have all been comprehensively improved. It can accurately complete precise leveling, slope trimming, pit digging, and ditch clearing operations, and is also capable of handling high-efficiency operations such as large-scale earthwork excavation, spoil removal, and site demolition. Coupled with a larger and upgraded cooling system, the high efficiency and even heat exchange effectively resist the high temperatures of summer and the high temperatures caused by prolonged full-load operation, significantly improving the machine's continuous working stability and reliability.
