YowCheeKeong, YTLplant andmachinerymanager, said, “We’vehadaPotain tower crane inour
fleet since1984, butwe recently invested in sevennewunitsbecauseof the significant improvements
that Potainhasmade.
“Theyareextremelyhighperformingcranes that areeasy touseand simple toerect.Wecanalso

in the future.”
Sevenof YTL’sPotainMCR225A tower cranes
areworkingon theFennel Sentul project in
KualaLumpur,Malaysia. Thecraneswillwork16

measuringup to40metres in length, acompany
spokesperson said.
The 5,001st Potain crane is handed over to
Malaysia-based construction company YTL.

Manitowoc has produced 5,000 tower cranes inChina since 2006
Intelligent excavator
Integrated guidance systems
and stroke sensing hydraulic
cylinders have been used to
improve accuracy, efficiency
and safety on a new 20 tonne-
class excavator.
K
omatsuhas launched its intelligent
machine control excavators inEurope.
The PC210LCi-10, unveiled as a
prototype at last year’s Bauma exhibition,
features a newmachine control and guidance
system that improves accuracy, efficiency and
safety.
Komatsu says its control and guidance system
means the operatorwill no longer have toworry
about digging toodeep or damaging a target
surface, improving efficiency, precision and safety
on site.
The system startswith a factory installed, fully
integratedmachine control system that includes
stroke sensing hydraulic cylinders for the boom,
arm andbucket, developedbyKomatsu for
precise, real-time bucket edge positioning.The
InertialMeasuringUnit (IMU) gives precise
machine orientation anddeterminesmachine
angle from gyro and accelerometer data, while
an on-boardGNSS receiver is used toprovide
the real time position of themachine.This
information is used to automatically prevent
digging beyond the target depth on any given
task.
MalMcCoy, productmanager for hydraulic
excavators and intelligentmachine control
products said, “This latestKomatsu technology
is a revolution inhowhydraulic excavatorswill
be used in the coming years.The ability of the
PC210LCi-10 to achieve andmaintain grade
withminimum effort from the operator is
awesome”.
Komatsu says its system lets the operator focus
onmovingmaterial efficiently, without worrying
about digging toodeep.The touch screen control
box features a facing angle compass, a light bar
and audio guidance anddisplays information
such as real-time “as-built” status, amagnified
fine grading view or a 3Dplan view.
The company says that by setting 3Ddesign
data on the control boxmonitor, staking
canbe reduced or eliminated, as can
surveying andfinal inspection. Safety
can alsobe greatly improved, with less
people needed on site andnear the
machine.
The PC210LCi-10’s operatingweight
varies from22.6 to23.5 tonnes,
depending on options and configuration,
with a 123 kW engine.Other
specifications are identical to those for
theKomatsuPC210LC-10.
