Expect new equipment to debut at the Oregon Logging Conference (OLC), like the new Cat B Series track feller bunchers. The feller bunchers feature a new, upsized undercarriage, more horsepower and a new hydraulic design for improved multifunctioning performance.
“Major enhancements to these limited tail-swing track feller bunchers will give loggers faster cycle times, more uptime and longer machine life,” said Keith Hicks, Caterpillar Forest Products product performance engineer. The Cat 522B is a leveling machine for select or clear-cut logging in rough, steep terrain. The Cat 521B is a non-leveling model best for plantation thinning, swamp logging, medium production clear cut, and high production biomass applications.
All the undercarriage rolling components of both models have been upgraded to D7 size hydraulic excavator type. “Track shoes, link assemblies, idlers, track rollers and undercarriage frame structures have all been upsized. Undercarriage life expectancy even in tough terrain is going to increase significantly,” Hicks said.
