Cat knuckleboom loaders are known for superior multifunction capability, excellent visibility and heavy-duty booms and structures. Now the Cat C Series knuckleboom loaders feature a new more fuel efficient power system, an upgraded hydraulic system for greater reliability and significantly more lift at full reach than previous models. Like the smaller model, the Cat 579C, now has a right-side operator's cab with a walk-up platform and enlarged doorway for safe access to the cab.
