HYUNDAI HX220A L
upfront but much like the machine
control expense, Declercq sees it as
a longer-term investment.
“We are in the transition period
going from Stage IV to V so that
means up to mid next year we will
have a limited stock of the Stage IV
engines but the customer is in
comfortable position where he can
choose which model he wants.
“Why would he choose Stage V?
First of all, it is of course more
environmentally-friendly, but it also
has new technology on the engine
for fuel saving.
“We also built in new hydraulic
technology, which also give
additional fuel savings so actually
the choice the customer needs to
make is not only whether he wants
to become more environmentally
friendly but also whether he wants
to save fuel costs,” he says.
Under the hood
The 22 metric ton crawler excavator
is one of the first in Hyundai’s range
to be Stage V ready. Cummins is the
chosen engine supplier and its B6.7
unit provides the machine 130kW
(174hp) of net power.
To meet the stricter emission
guidelines, the exhaust gas
recirculation (EGR) system has
been removed, while a diesel
particulate filter (DPF) has been
added at the exhaust end and the
injection of Ad Blue has been
optimized.
With the EGR-free
architecture, complexity
is reduced which improves
reliability but also reduces
the space required for the
cooling system. In addition,
the aftertreatment system
combines the DPF, Selective
Catalytic Reduction (SCR) and

urea dosing in one unit that is 50%
smaller and 30kg lighter than the
supplier’s prior system.
“Instead of previously having two
canisters for the exhaust, we are
down to one that is individually
slightly larger but in the end the
space it takes in the engine hood is
60% less,” says Declercq. “When the
service technicians saw the result,
they were very happy because now
there is space around the engine and
it is easily accessible for servicing.”
All-rounder
Through Hyundai’s Hi-Mate
platform, advanced troubleshooting
diagnostics reports
are sent to the dealer to quickly
inform them of any engine
failures, ensuring a rapid
response and machine
downtime is kept to a minimum.
Electronic pump flow
control supplied by Kawasaki
automatically tailors the oil flow to
the task at hand increasing the fuel
efficiency of the machine.
Inside the cab, the choice of
an in-house built joystick or an
optional Engcon version is available
but the touchscreen display of the
outgoing model is retained.
“You can control all of the
functions of the machine from the
cluster, so the operator will notice
that there aren’t many switches
inside the cab as it is all centralized
there,” says Declercq. “It’s not
a rocket ship, we’ve intentionally
designed it to be as simply operable
as possible.”
Redesigning the access door and
cab roof has increased the amount
of glass coverage, which, along with
the lower profile of the engine hood,
has noticeably improved visibility
for the operator.
Crawler excavators in this class
are often the touchstones by which
an entire range is judged; and on all
fronts, the HX220AL is making a
good case for Hyundai. Peter
Sebold, another Hyundai product
specialist adds: “The HX220AL
kicks off the introduction of our
new A-series – a range of machines
with intelligent features, that will
cater to the demand of our modern
society for smart machines, clean
machines, but still robust and
productive powerhouses. And that
is Hyundai’s strength – solid and
unbreakable products.” iVT
THE DOOR OPENER
Hyundai is enabling its customers
to boldly go where they previously
couldn’t with another of its new
machines. At just 73cm wide, the
HX10A is smallest in the OEM’s lineup
and with a two-column foldable ROPS bar
is able to pass through standard size doors.
Powered by a Yanmar diesel engine, the
1-metric ton mini excavator can also be
powered by a separate mains-powered
electro-hydraulic unit for emission-free
indoor work.
“There are connectors in the back of
the machine where you can attach hydraulic
hoses,” explains Laurent Declercq,
a product specialist at Hyundai Construction
Equipment Europe. “The separate unit is an
electric motor with a hydraulic pump, which
supplies hydraulic oil to fluid to the machine.
The hydraulic hoses can be up to 10 meters
from the power unit, so you can work fully
emission free.”
Additionally, with the mono-boom
mounted on a swing-post, the vehicle can
dig close to a wall and confined spaces.
“We call it our ‘door opener’ and for our
customers it can be an entry product or
complementary to their other machines
for indoor jobs,” says Declercq.
