Two intelligent switchable working modes (Standard, Heavy Load) switchable via central color LCD monitor to match farm land leveling, municipal narrow pipeline trenching, light gravel crushing and villa garden precision shaping construction tasks. All hydraulic cylinders adopt built-in anti-shock buffer valves to eliminate micro impact vibration during mixed soil and small stone light-load operation. Factory pre-installed full small-flow hydraulic breaker pipeline interface, compatible with 55-75mm mini hydraulic hammer without secondary pipeline refitting. Exclusive CAT load sensing hydraulic control dynamically distributes dual pump output flow according to real-time operation load demand, reduces idle fuel consumption by 12% and improves overall construction efficiency by 16% compared with old generation 7-ton compact excavators. Auto idle function automatically reduces engine speed after joystick idle for 4 seconds to cut extra fuel waste, operation movement smooth and precise, widely suitable for urban municipal renovation, rural road maintenance and residential landscaping projects.
