Cat track harvesters help loggers boost production in the woods, and their efficiency and durability help increase profitability. They are designed with the best combination of lift capacity, swing torque, and tractive effort ratios for high production. The Cat 541 and the Cat 552 Series 2 models are full tail swing machines designed for high-production clear-cutting or final felling in rough terrain. The 552 Series 2 is a levelling machine for improved operation in steep terrain, and Caterpillar also offers steep slope harvesting enhancements for this model. The Cat 521 and 522 B Series machines are near-zero tail swing machines, which are more attractive for harvesting in select cut and thinning applications because they help reduce damage to the residual stand. The 521B is a non-levelling model best suited for plantation thinning, biomass harvesting, and medium- production select or clear-cut applications; the 522B is a levelling machine for select or clear-cut logging. The 541 and 542 Series 2 and 521 and 522 B Series machines are equipped with the Cat C9 ACERT The combination of swing and lift capacity reduces cycle times and increases production Jared Dunn, Caterpillar 226 kW (303 hp) engine, which has a proven track record of reliability and durability. Power management software is tailored for the unique engine-hydraulic interactions in a forestry application and delivers a high level of machine performance. The closed centre hydraulic system includes fully adjustable electric over hydraulic controls and plentiful flow capacities; two or three pumps, depending on the configuration, power the hydraulic system to give loggers smoother multi-functioning. An on-demand reversing fan helps keep the radiator debris- free, and the high-capacity cooling system keeps the engine running at the proper temperature, optimizing performance, durability and fuel economy. Large structures such as swing bearings and booms have been designed for longer life and durability. The tracks and all undercarriage rolling components are high-grade to extend track life, The Cat 541 and the Cat 552 Series 2 models are full tail swing machines designed for high-production clear-cutting or final felling in rough terrain 46 International Forest Industries | FEBRUARY / MARCH 2018 reduce repair costs, and increase stability. The machines have excellent ground clearance and an open carbody design, increasing mobility by eliminating interference with obstacles. “Strong drawbar pull, along with excellent ground clearance and the ‘open tunnel’ undercarriage design, makes for a highly manoeuvrable machine that easily climbs steep slopes,” said Jared Dunn, Product Application Specialist for Caterpillar Forest Products. The Cat PRO (Parallel Reach Operation) System gives operators the ability to complete a smoother, fluid harvesting motion. One joystick either extends or retracts the work tool by combining both the main and stick boom functions. For feller buncher configurations, the head is kept level as well. By combining these functions in one joystick, the operator can efficiently move the head in a planar, parallel motion relative to the ground. The Cat PRO System, adjustable for different applications and varying slopes, helps new operators learn faster, and it increases efficiency and reduces fatigue for seasoned operators. LED lights are standard, and the purpose-built forestry cab offers operator protection and comfort. It meets ROPS, FOPS, OPS, OR-OSHA and WCB regulations and standards. The ISO mounting system reduces noise and vibration, increasing operator comfort. The 541 Series 2 and 552 Series 2 excel in lift capacity, reach, and working envelopes, which deliver high performance. “The combination of swing and lift capacity reduces cycle times and increases production,” said Dunn. “The balance between lift and tipping load capacity, along
