CONSTRUCTION: EXCAVATORS
U
nderlining its intention of competing
on a broad front in all sectors of the
construction and mining equipment
business, Hyundai’s top-end excavator in
the 100 t-plus sector endorses the compa-
ny’s commitment to large-scale investment
in developing new products and new mar-
ket opportunities.
Building on Hyundai’s experience with
the successful 50 t and 80 t high capaci-
ty models, the all-new 120 t R1200-9 has
been conceived with an eye on the expand-
ing worldwide mining and quarrying sector,
where the demand for efficient, large-scale
mass excavation in minerals extraction and
overburden removal has fuelled an increase
in sales of large mining trucks and the
equipment to load them.
The R1200-9 is powered by the high-per-
formance 23 litre, 6-cylinder Cummins
QSK23-C rated at 760hp (567 kW). Particu-
lar attention has been paid to the insulation
to achieve low internal and external noise
levels.
This version of the new 120 t machine
is equipped with a heavy-duty 7.55 m
back-actor boom, 3.4 m dipper-arm, and
6.7 m³ bucket – a combination which gives
a maximum digging depth of nearly 8m,
an outreach of 13.76 m, and a load-over
height of 7.8 m. Maximum breakout force
at the bucket is a massive 64.9 tons – and
with three selectable power modes (Power,
Speed & Economy), this is clearly a machine
designed for extra-heavy digging duties and
loading of large capacity dump-trucks.
In order to achieve optimum precision, Hyun-
dai engineers have designed the R1200-9’s
hydraulic system to provide the operator
with super fine touch and controllability.
Improved pump flow thereby minimises fuel
consumption and improved spool valves are
engineered to provide more precise flow to
each function with less effort.
In addition to power and precision, the
R1200-9 is robust and durable when taking
into account the strengthened undercar-
riage, a design that makes for an excellent
production rate in quarries and mines. Dura-
ble full track rail guards keep track links in
place and track adjustments are made easy
with standard grease cylinder track adjust-
ers and shock absorbing springs.
Special attention has been given to the cab
design which allows a clear, open and con-
venient interior with excellent visibility, plac-
ing the operator in a perfect position to work
safely and securely.
An advanced 140 mm wide LCD display al-
lows the operator to select personal machine
preferences and monitor crucial machine
data. Power and work mode selection, ma-
chine diagnosis, optional rear-view camera,
maintenance check lists, start-up machine
security and video functions have been in-
tegrated into the menu to make the machine
more versatile and the operator more pro-
ductive.
