Digging deep
savings of up to 8% compared with the Tier 3 machine. This
efficient engine produces 281 hp (210 kW) at just 1900 rpm,
driving a twin pump, load sensing hydraulic system to deliver
strong digging performance. When equipped with a 6.45 m
main boom and a 2.21m dipper, the JS360 delivers 25,300 kgf
of dipper tearout and 27,716 kgf of bucket tearout force.
The JS360 is also available in XD demolition specification
or with a 21 m long reach boom for waterway maintenance
and dredging operations. The JS360LC XD features added
protection for both themachine and the operator, including an
XD cage for the cab, heavy duty undercarriage and side impact
protection.
Also available is the JS360 HRDwith a modular three-piece
demolition rig, the machine offers 21 m of reach from the
ground to the bucket pin.
Meanwhile, New Holland’s E385C crawler excavator, which
weighs in at a hefty 38 tonnes, is equipped with a powerful
common-rail engine, which maximises on fuel efficiency. The
E385C offers an eco working mode, and meets Stage IIIB EU
specifications on exhaust emissions, with its integrated cooled
exhaust gas recirculation (EGR) system.
Designed for heavy-dutywork, the E385C comes with a Bulk
ExcavatorHeavy (BEH) configuration, which includes a shorter
monoboom andpoweredbucket linkage to give greater stability
and higher breakout force. A bigger bucket is available for the
E385C BEH, which can carry +18%more material than the
standard version.
At the lighter end of the excavator spectrum, Komatsu has
introduced its 18-tonne PC170LC-10 to the Europeanmarket.
Following on from the PC160LC-8, Komatsu says the dash-10
offers between +5% and +15%more lift capacity.
Driven by an 115 hp (86 kW) engine with a variable-flow
turbocharger, the PC170LC-10 is also up to 10% more fuel
efficient than its predecessor.
Cab comfort
Tipping the scales at 42.6 tonnes, the newHyundai R430LC-
9A is the latest addition to the manufacturer’s Robex excavator
range. The new Stage IIIBmachine, which is being rolled-out
across Europe, slots in between the existing R380LC-9A and
the R480LC-9A. The R430LC-9A’s new economy mode helps
operators conserve fuel. According toHyundai, it offers 5% fuel
savings in comparison to previousmodels.
However,what sets this excavator apart is the focusonoperator
comfort.
The R430LC-9A features a Hyundai -9A cab, which offers
a fully adjustable suspension seat and armrests. The joystick
consoles are also adjustable in height to ensure less operator
fatigue. A fully automatic air-conditioning system provides a
constant ambient temperature.
In-cab technology includes a 7-inch (178 mm) LCD colour
touch screen for programming personal machine preferences,
includingworkmodes, self-diagnostics,maintenance check lists
and start-up machine security codes. The screen also enables
the operator to see the rear view camera, providing all round
visibility.
Launched atMarch’sConExpo-Con/Agg exhibition in theUS,
Luigong’s 50-tonne 950E excavator follows in the tracks of the
Chinesemanufacturer’sD series. Again, attentionhas beenpaid
to operator comfort with the 950E offering one of the largest
cabs in the industry. The cab windows are widened for better
visibility, especially the right downward view for steering and
excavation. An enlarged skylight with rolling sunshade provides
excellent visibility and good ventilation.
The on-board LCD monitor displays machine operational
states, warnings, audible alarms and maintenance information
in a choice of 10 languages.The LCDmonitor also serves as the
display for the rear view camera, which improves safety.
A

equippedwith a hydraulic rotating
grabwas used to get theRiver Severn
flowing again in theUK.
WMPlant Hire, based inShropshire,
provided the long reach excavator to clear
500 tonnes of debris from the arches of
Worcester’s historic bridge. This had built up
following flooding and therewas concern the
lodged debris could restrict the flow of water
and cause additional lateral loading and
stress on the bridge structure.
The project was co-ordinated by the local
council, emergency services, environment
agency, and highway authorities.
WMPlant Hire operates one of the largest
fleets of long reach excavators in theUK.
