Three New Compact Track Loaders added to Cat Range
27/01/2009
Three models of compact track loaders,
the 279C, 289C and 299C, are the newest additions to the Caterpillar®
line of rubber-track loaders. The new loaders feature durable,
steel embedded track and steel undercarriage components for maximum life
in aggressive applications and deliver solid traction and reduced wear
on sites with sticky, rocky soils.
The new compact machines combine
a freshly engineered suspension-type undercarriage, designed and built
by Caterpillar, with the chassis of their multi terrain loader counterparts,
the 277C, 287C and 297C. The fully suspended undercarriage employs four
independent torsion axles for a superior ride and excellent bucket load
retention. Class leading track-on-ground of almost 1767 mm provides good
flotation and traction, low ground pressure and long track life.
All three models feature two-speed
drive systems for fast movement around large sites while the Caterpillar
exclusive drive motor seal guards extend the lives of seals and final drives.
The electrohydraulic joystick control of the drive motors delivers
straight-line tracking, and electronic torque management optimises productivity.
The new compact track loaders complement
the Caterpillar multi terrain loaders, which feature very low ground pressure
for high flotation and little ground disturbance. Multi terrain loaders
also offer the best ride and highest travel speeds of all compact tracked
machines. Now you can choose the machine that best suits your primary applications.
Robust new undercarriage
At the heart of the Caterpillar
compact track loader design is a robust new undercarriage. It uses an external-type
sprocket, steel track rollers and idlers, conventional spring-type (grease-adjusted)
recoil mechanism and rubber tracks that incorporate the reinforcing strength
of steel—both as steel cords that run longitudinally through the tracks
and as steel inserts at the sprocket-engagement points. The design emphasizes
durability and aggressive traction, suiting it particularly well for applications
in which maintenance, operator technique and underfoot conditions might
present challenges.
Power train and hydraulics
Powering the three new loaders
is the Cat C3.4T diesel engine, an inline, four-cylinder, turbocharged
model with a 3.3 litre displacement. The engine is designed with premium
Caterpillar features, including high-load-carrying bearings, induction-hardened
cylinder liners, forged-steel/super-finished crankshaft, positive-displacement
gear-pump lubrication system and gear-driven coolant pump.
The engine powers a two-speed hydrostatic
drive system, which provides a travel speed of 13.6 kilometres per hour
in second range—and which is standard equipment for the new 279C, 289C
and 299C models. The drive system is engineered to electronically balance
torque and speed delivered to the tracks, a feature designed to promote
optimum performance and fuel efficiency in any application, whether aggressively
digging in a sticky clay bank, loading trucks or doing drawbar work. To
complement the efficient design of the drive system, the drive motors incorporate
Caterpillar’s exclusive seal guard, which helps protect the motors from
damage.
Electronic control of the drive
system allows continual fine-tuning of the engine, drive pumps and drive
motors to deliver controlled tractive effort, but always in combination
with ample hydraulic power for the implement (lift and tilt) and auxiliary
circuits.
The Advanced Machine Information
and Control System allows the operator to select the level of loader-arm
and bucket responsiveness, while also providing 10 work-speed selections.
Operator/technician amenities
To enhance controllability and
ease of operation, the new models are equipped with a foot throttle, which
allows the operator to adjust engine speed to suit the application, while
also reducing sound levels and conserving fuel. This feature complements
the independently adjustable joystick controllers, which are console-mounted
to provide ample forearm support. The operator station is equipped with
a suspension seat.
The enclosed ROPS cabin is sealed,
pressurised and heated, with ventilation air filtered to eliminate dust.
An air-ride seat and air-conditioning further enhance the operator environment.
The design positions the seat and surrounding enclosure to enhance visibility,
and a quick-release door and safety interlock system prevent accidental
machine movement. Lift-arm safety braces are designed for easy use,
and routine-maintenance features include a rear door that swings open 90
degrees to provide ready access to service points. Also, the cab tilts
up for wide-open access to drive-system and hydraulic components.
