Product Description
Engineered for precision and reliability, this 4-ton mini excavator delivers professional-grade performance through proven Japanese componentry. Powered by a Yanmar 4TNV88 engine producing 27.1 kW at 2200 rpm, the XE40 combines a water-cooled 4-cylinder design with a 2.19L displacement for consistent output across demanding job sites. Hydraulic architecture features a Japanese Fujikoshi variable pump paired with a gear pump, delivering 110 l/min main flow at 21 MPa system pressure for responsive control and efficient cycle times.
Operational capabilities include a maximum digging reach of 5,810 mm and depth of 3,600 mm, supported by 23.2 kN bucket digging force. The compact footprint—5,455 mm transport length and 1,650 mm width—enables access to confined urban environments while maintaining 30° climbing ability. Plunger hydraulic motors drive both rotation (13.5 rpm) and travel functions (4.2/2.6 km/h dual-speed), ensuring smooth operation under load. With a 1,721 mm track ground length and 23.6 kPa ground pressure, this Xuzhou-manufactured unit balances stability with minimal surface impact. Currently available in Shaoxing, Zhejiang, ready for immediate deployment.
