CONSTRUCTION: EXCAVATORS
H
itachi focuses on building excava-
tors, not every other kind of machine.
The results are, more reliability and
higher productivity.
Hitachi has a rock-solid reputation as they
can lay claim to the conception that over
one third of all the hydraulic excavators op-
erating throughout the world are Hitachi. All
their excavators such as the EX1200-6 are
engineered to give the flexibility to handle
many different jobs. As a total package the
customer gets stronger horsepower, effi-
cient engines, comfortable cabs, advanced
hydraulics, tough frame and powerful arm
and bucket digging forces.
With the EX1200-6 the advanced hydrau-
lic system provides, combined bucket tilt,
boom raise and fast pass speeds which de-
livers quicker loading times. In addition, the
EX1200-6 has a stronger boom and bigger
bucket for increased lift capacity and the
smoothest precise operation.
For even higher productivity, operations get
switchable power modes, adjustable for ev-
ery job. The power modes include a deep-
end mode that gives you the muscle to get
the heaviest jobs done and a fuel saving
mode for less heavy jobs, which significantly
reduces fuel costs.
The EX1200-6 also raises productivity with
an exclusive auto-level crowd mechanism
that allows for easy one-lever crowding of
the bucket into the material at a constant
level.
The well insulated pressurized cab ensures
operator comfort under all conditions thanks
to the highly efficient heating/air conditioner
system. Being a particularly large and roomy
cab, operators of various sizes can be ac-
commodated without any discomfort.
The EX1200-6 is built with uptime in mind.
Features such as heavy duty rigging struc-
tures and reliable hydraulic, electrical un-
dercarriage components.
The rigid box frame is designed to resist
bending and twisting forces and provides
strength and balance to handle heavy dig-
ging jobs and mated to the heavy duty under-
carriage with large diameter swing bearing,
provides increased reliability and durability,
combined with a high stability factor.
The Cummins, 6-cylinder, EPA Tier 2, eco
friendly diesel engine adds to the produc-
tivity and efficiency of the EX1200-6. With
567 kW (750 hp) on tap, combined with a
3468 Nm of torque, the Cummins engine
provides this mammoth excavator with the
power source to drive the three main vari-
able displacement hydraulic pumps and the
gear driven pilot pump.
The design characteristics of the EX1200-
6 has reduced the service inspection and
maintenance times to a minimum. The unit
is loaded with time-money saving mainte-
nance features like easy-to-check sight
gauges and fluid reservoirs, quick-change
remote-mounted filters, advanced self-di-
agnostic and extended filter replacement
intervals.
