All new
from JCB
JCB has unveiled an array of
newmachines, including its
first ever 10 tonne excavator.
Improved fuel economy is a
theme it is stressing across
these new launches, as
Chris
Sleight
found out
J
CBhas been rollingout newproducts
acrossnumerous product ranges,
including tracked,wheeled andmidi
excavators,wheeled loaders, telescopic
handlers, rough terrain forklifts, newvariants
to its backhoe loaders andgenerators from
JCBPowerProducts.
Perhaps oneof themost interesting areas is
themidi excavator segment. This is adifficult
area todefine accurately, but the general
meaningof ‘midi’ is taken tomeanbigger than
amini excavator, but smaller thanmainstream
excavators, so about 6 to10 tonnes operating
weight.New additions in this area include
the6.5 tonne class 65R-1, a reduced tailswing
model – a replacement for the8065RTS.
Meanwhile, abrandnew addition to the
range is the100C-1– the first 10 tonne class
excavator JCBhas ever built. The company
said itwas basedon the frameof the8.6 tonne
86C-1midi, butwith amorepowerful engine,
largerdig end and increasedhydraulic capacity
toboost performance.Keymarkets are seen as
France and theUK.
The traditional overhanging counterweight
machineoffers amaximumdiggingdepthof
4.6m (15 ft), adumpheight of 5.6m (18.4 ft)
and a reach at ground level of 7.5m (24.6 ft).
Power comes from a55kW (73.8hp)Kohler
engine thatmeets emissions regulations
without theuseof adiesel particulate filter.
JCB said this powerunit offered a10% fuel
saving compared to competitivemodels. The
100C-1 alsohas an engine auto idle function
that drops engine revs after apre-determined
periodof inactivityup to30 seconds.
Another important feature is that all
the service intervals – includinggreasing
– are500hours. JCB said, “The500hour
greasing interval is probablyonly twice a
year, compared toweeklyordailyonother
machines.”
Furtherup theweight range, JCBhas added
thenew30 tonne class JS300 crawler excavator,
which replaces the JS290. There is a reduction
in internal noise to just 70dB(A) in the cab,
andother features include ahigh specification
JCB hasmoved toMTU engines for its
Tier 4 Final 457wheeled loader and
themachine also features the next
generation Command Plus cab
The new JS300 features a simplifiedmode selection
system and quieter cab than the JS290 it replaces
UK demolition contractor DRSDemolitionNational,
based in Avonmouth in Cornwall, has invested
close to £2million (US$3.2million) to shift its
fleet focus towards the use of Hyundai equipment.
Its order includes four R330LC-9A full demolition
specification excavators, four R220LC-9A full
demolition specification excavators, a 140LC-9A
and a 140LC-9, threeR80-9 excavators, anR55-9,
anR33-9 and anHL740-9Awheeled loader.
Themachineswere supplied throughMolson
Group, also based in Avonmouth, who is the largest
Hyundai dealer in the UK.
The newmachines are nowworking on a range
of jobs around Cornwall, including the demolition
of the oldest hotel inNew Polzeath, the Atlantic
House.
Cat introduces tilt coupler
Cat has launched a new tilt coupler for its 5 and 8 tonnemini excavators in the shape of
its newDual-Lock Tilt (DLT) pin grabber hydraulic coupler that allows use of attachments
through a 180° arc.The design provides optimum flexibility and efficiency in applications
including demolition, accommodating compatible pin-on attachments and permiting the use
of buckets in a front shovel configuration.
The DLT coupler’s design allows tools to be changed from the cab and a visible locking
mechanism assures operators that tools are securely attached. Its primary locking system
uses a wedge plate positioned via a hydraulic cylinder with integrated check valve and a
spring-applied secondary lock hydraulically released bymeans of a separate circuit.
It features an enclosed design with no external cylinder rods ormoving parts, resulting
in optimum reliability, longer component life and low cost of ownership, says Cat. All internal
components subject to wear are heat-treated formaximum service life, thus extending
the life of bearings, seal grooves and gear
surfaces. A newly designed rotary actuator
provides up to 35%more holding torque,
reduces overall weight by 15% and simplifies
hydraulic line routing. In addition, the helically
cut and hardened gears used in the actuator
ensure positive action and long-term
durability.
Coupler weights are 112 kg (247 lb) for
5 tonne class excavators plus the 903C
CompactWheel Loader and 180 kg (398 lb)
for 8-ton-class excavators. The DLT coupler
is available for 305C/D/E and E2models,
305.5D/E and E2models, and 308E and
E2models.
