Four intelligent switchable working modes (Heavy Load, Standard, Economy, Fine Precision Control) switchable via central color LCD monitor to adapt highway widening, residential foundation excavation, bulk soil loading and medium hard rock crushing construction scenarios. All hydraulic cylinders adopt thickened cylinder barrel and built-in high-pressure anti-shock buffer valves to eliminate strong impact vibration during long-time continuous earthmoving and rock breaking operation. Factory pre-installed full medium-heavy flow hydraulic breaker pipeline interface, compatible with 100-140mm hydraulic hammer without secondary pipeline refitting. Exclusive CAT Intelligent Load Sensing hydraulic control dynamically distributes dual pump output flow according to real-time load demand, reduces idle fuel consumption by 13% and improves overall construction efficiency by 18% compared with old generation 20-ton medium excavators, delivering reliable, stable and fuel-saving digging performance for urban highway reconstruction, rural land consolidation and medium stone yard projects. Auto idle function automatically reduces engine speed after joystick idle for 4 seconds to cut unnecessary fuel waste.
