Caterpillar Launches Compact Track Loaders

By Tom Hale -- Associated Construction Publications, 8/26/2008

In its first-ever web launch of a Cat product, Caterpillar announced its C Series compact track loaders. This new three-model – 279C, 289C and 299C – addition to the Caterpillar line of rubber-track loaders offers the flotation and ride of tracks with a Caterpillar-designed steel undercarriage to take on harsh applications. The new tracked machines deliver solid traction and reduced wear on sites with sticky, rocky soils.

According to Caterpillar, the fully suspended steel undercarriage featured on the C Series compact track loaders provides a smooth ride and offers better material load retention, which means greater productivity. The fully suspended undercarriage employs four independent torsion axles.

Power Train & Hydraulics

The Caterpillar 279C, 289C and 299C compact track loaders are equipped with Cat C3.4T diesel engines. The 279C offers a net power of 82 horsepower and a rated operating capacity of 3,200 pounds at 50 percent of tipping load; the 289C offers a net power of 82 horsepower and a rated operating capacity of 3,850 pounds at 50 percent of tipping load; and the 299C offers a net power of 90 horsepower and a rated operating capacity of 4,150 pounds at 50 percent of tipping load.

All three models feature two-speed drive systems, with a maximum speed of 8.5 miles per hour. Caterpillar says the electrohydraulic joystick control of the drive motors delivers straight-line tracking, and electronic torque management optimizes productivity. Caterpillar exclusive drive motor seal guards extend the lives of seals and final drives.

At the heart of the Caterpillar compact track loader design is a 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.

Because the undercarriage is suspended by a pair of torsion axles on each side of the machine, each track assembly can flex independently, resulting in a softer ride for the operator, reduced shock loads through the machine, and minimal spillage from the bucket in rough going. And with nearly 70 inches of track-on-ground, the 18-inch-wide tracks exert low ground pressures, while providing added traction and long service life.

Operator Comfort

Operator comfort is another key feature of the compact track loaders. A spacious cab provides a comfortable work environment. 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 optional enclosed ROPS cabin is sealed, pressurized and heated, with ventilation air filtered to eliminate dust. An available 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.
