Structures

The 539 Knuckle boom loader’s main structures (main frame, platform frame and boom and stick) are purpose-built for the stress loads of pull-through delimbing and truck loading.

Attachments

Factory installed options include a fifth-wheel trailer, pull-through-delimber with topping saw, continueous rotation grapple etc.

Engine

The turbocharged and aftercooled Cat 3126 DITA engine provides optimum power and fuel efficiency. The four-stroke cycle design delivers long power strokes and efficient fuel combustion with low emissions. The engine is easily maintained. All engine service points are located on the back side of the engine and are easily accessed through swing-out doors at the back of the loader. Turbocharger enhances performance and engine efficiency, especially at high altitudes by packing more air in the cylinders for excellent combustion. Jacket water aftercooler reduces smoke and emissions by providing a cooler, more efficient combustion. This also extends the life of the piston rings.

Air intake heating eases cold weather starting. Individual, high-pressure unit injectors increase fuel economy with low emissions. The radius cone injector nozzle provides excellent contact with the cylinder head sleeve to ensure tightness with the combustion chamber.

Fuel pre-filter and water separator element combined with two high efficiency micron filters ensure excellent fuel cleanliness, provide long injector life, fuel system durability, and protection.

Operator’s Station is designed for comfort, safety and ease of operation. It has such features as an ergonomic seat, integral pilot controls and excellent sight line to the work area.

Caterpillar instrument panel includes: engine service hour meter; voltmeter; gauges for hydraulic oil temperature, fuel level, engine oil pressure, coolant temperature; a two-stage system warning monitor.
