With Commins QSL9 engine and customized XCMG torque curve, XE380DK has low-speed and large-torque output and low fuel consumption under the heavy-load mode. With straight-flow air filter, it can meet requirements in medium- and heavy- gray conditions; with low intake resistance, it can reduce engine fuel consumption and prevent the engine from early grinding. The detachable pre-filtration function is integrated and the full-life filtration efficiency is over 99.99%. The large capacity rock bucket with the double circular-arc design structure reduces the resistance during excavation and makes it easier for material loading and unloading.
