Cat Forest Products recently launched the new B Series knuckleboom log loader with the introduction of the Cat® 559B. The loader features an enhanced engine and hydraulic power system that improves fuel economy and gives the operator more control to match the loader’s power output to job requirements. Reduced engine and fan speeds, a reengineered hydraulic pump and bigger hydraulic lines allow more efficient use of horsepower to save fuel while maintaining performance. The new pump also decreases heat generation, resulting in cooler hydraulic system temperatures. Loader performance is further improved by a 15% increase in swing torque and modified main control valve spools that improve cycling to lower the boom faster. The increase in hydraulic line size also allows faster grapple action. Read more....
