XCMG Factory XE400DK Engineering Construction Machinery Used 40 Ton Crawler Excavator

XCMG XE400DK hydraulic excavator is suitable for earth and stone construction projects such as municipal construction, highway bridges, housing construction, road engineering, farmland water conservancy construction, port construction and so on.

I. More energy-saving and environmental friendly

1. By adopting Cummins imported electronic fuel injection engine, the machine has stronger power and higher fuel economy.

2. High pressure common rail system realizes optimum fuel injection control and effectively improves combustion efficiency.

3. With optimized engine power curves and low-speed and large-torque output, the fuel consumption is greatly reduced while providing strong power, which satisfies dynamic balance and economy of power output and fuel consumption in heavy-duty mode.

II. More reliable and durable

1. Lengthened and widened heavy-duty undercarriage, combined with reinforced exclusive working equipment for mines, bring better stability and higher reliability, which can satisfy heavy-load construction in various working modes.

2. Exclusive double grouser track shoe for mines with enlarged plate thickness and track tooth height has better abrasive resistance and long service life.

3. Reinforced mine type working equipment combined with high pressure system design ensure the whole machine has the strongest digging force among the machines of the same level so as to cope with various working modes easily.

4. The standard oil-bath air filter satisfies the demand for cleaning of air inlet system in heavy dust working mode so that the replacement period of air inlet filter element is prolonged. It provides better protection for engine, prolongs engine service life and greatly reduces maintenance and usage cost of users.

5. Oil return filter is equipped to sufficiently filtrate the dust in hydraulic oil so that the hydraulic system is kept clean.

6. The accumulator is added to absorb pressure fluctuation so that high reliability of system and pipelines is ensured.
