Knuckleboom Loaders



No matter what logging job you’re on, the Caterpillar Loader will make your day more productive, profitable and comfortable.

Engineered Performance
Caterpillar loaders feature swing torque ratings up to nearly 108.4 kNm (80,000 ft-lbs). Combined with swing speeds up to 11 RPM, Caterpillar loaders provide excellent performance in all applications from shortwood loading, to drag loading, and pullthrough delimbing.

Boom Reach
Boom reach ranges from 8.2 m (27') on the 519 up to 10.9 m (36') on the 579.

Rugged, durable operation
The Caterpillar Loader is built using advanced design technology, for the strength and reliability needed to meet the demands of high production delimbing and loading.

Advanced features
Features such as smooth and responsive joystick controls, quiet comfortable operator stations and powerful Cat® engines provide the performance you've grown to expect from Caterpillar machines.

Power Train
Powerful CAT® engines meet applicable EPA emissions standards. Powerful inline 6 cylinder, four-stroke-cycle diesel provides smooth consistent power under challenging conditions in the forest.

Rugged Boom Design
Caterpillar loader booms are built tough with welded high-strength steel. Delimbing booms feature heavy steel castings at the base end, stick end, and cylinder junctions of the main boom.

Grapple Design
Continuous rotation grapples are constructed of wear resistant, high tensile steel with heavy-duty rotators designed for strenuous pull-through delimbing applications.

Subframe Stability
Caterpillar heavy-duty subframes are engineered for high reliability. Lock valves integrated into the stabilizer circuit reduce cylinder movement and increase stability. Wide stabilizer leg spread, large pad size and deep below grade reach provide a stable base.
