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.
