What’s New In Plant & Equipment
choose between maximum rimpull and maximum travel
speed via a convenient switch on the RH console. It also
automatically regulates speed during downhill travel.
The Deluxe cab features two side-entry doors, low-effort
electro-hydraulic joystick, suspended pedals, tilt steering
wheel, air-suspended and heated seat and optional security
keypad.
Options include the Road Feature and Load Feature
Packages, which include a new electronic, soft-touch keypad
for convenient control of most functions. The Road
Feature Package includes a Ride-Control system that cushions
boom cylinders when the machine is traveling with
a load in rough terrain, smoothing the ride and retaining
material.
Medium Sized Loaders
In the larger wheel loader range, the new Cat 950M (19,769
kg )and 962M (20,296 kg) wheel loaders feature a Cat C7.1
ACERT engines that also meet Stage IV emission standards.
The new engines deliver more power than their K-Series
predecessors and contribute to a potential
10% gain in fuel efficiency (25% better than
the H series). This was achieved from the
enhanced performance of the redesigned
hydraulic system and the new engine,
which works at a lower average speed and
creates less heat.
An improved interface between the
operator and machine controls further
boosts production potential, and the new
Cat Payload Measurement system enables
operators to confidently deliver exact
loads, while allowing managers to monitor
machine productivity.
The new models also feature major drive-train refinement,
new cab amenities, optimized Z-bar linkage and a
range of Cat Performance Series buckets and work tools
that expand overall machine versatility.
In the cab, the new electro-hydraulic joystick steering
is also available on the 950M and 962M featuring speed
sensing force feedback for unparalleled comfort and control.
A new multipurpose color touch screen display dramatically
simplifies the operator interface with machine
controls, rear vision camera and the new fully integrated
Cat Production Measurement system.
The mobile scale device accuately loads truck, stores
the data and can, via the optional printer, produce a receipt
of the amont of material loaded. This system is not
yet certifiable for accuracy, as required by local authoriaties
and regulators, but it is only a matter of time before the
technology proves itself. At that time, it will be possible to
dispense with manned weightbridges.
Stair-like steps and repositioned grab handles facilitate
safely entering and exiting the M-Series cab, as does the
wider door opening. An available switch in the electronic
service center allows ground-level unlatching of the door,
which then swings open via a gas strut.
A heavier counterweight and a larger bucket capablity
means 20 t. trucks can be loaded in 3 passes.
Improving Markets
Paolo Fellin, Vice President - Global Construction &
Infrastructure said that they expect to see a continued
growth out of the depressed markets within Europe but it
will become a more competitive market.
One reason for this could be Chinese manufacturers
looking to export as local demand
decreases. There is a general concensus
that the markets will find a new level some
58% below the peak of 2008 but signficantly
higher the the low experienced in 2009.
Mr Fellin explained how fully integrated
technology is enabling Cat customers to
benefit. In truck loading, by loading to optimum
level, maximum efficiency is achieved
with less spillage from overloading. For
highway trucks, overloading can result in a
costly fine, being able to measure loading
eliminates this.
Enhanced bucket loading features, return to dig, etc
also contribute to fewer passes which translates to less
fuel.
Fleet owners and plant hire companies have also welcomed
the opportunity to manage their equipment in real
time. To see where delays are occuring and to track machine
usage and location.
