The Ponsse Bison has a transmission equipped with a stepless gear ratio change, which means there’s no need to stop when switching to the fast range from the slow range. Working in all types of terrain is much faster – just hit the throttle. With Active Frame as standard equipment, driving is smooth. It prevents the cabin and operator from swaying. To top it all off, the engine’s revolutions per minute remain nearly constant regardless of speed. This has a significant impact on fuel consumption. Bison’s low-emission engine is highly economical. It can carry 16 tonnes with unprecedented ease from forests to storage sites.
Komatsu has updated its 875 and 895 forwarders with new features designed to increase productivity, simplify daily maintenance, and maximize profitability. The 875 (16 metric tonnes) and 895 (20 metric tonnes) have more engine horsepower at 254-hp and 287-hp, respectively. These engines feature a new, more user-friendly DEF system, a new exhaust system and new, lower-maintenance hydraulic lifters. Both models feature the new MaxiXT control system, which continuously monitors and optimizes engine, transmission, hydraulic, and crane performance. A new drive-by-wire steering system replaces the former steering wheel and allows for higher travel speed. The HST transmissions have a special hydraulic retarder overspeed protection that keeps key driveline components from over-revving.
Available in a six-wheeled or eight-wheeled configuration, the 910G and 1010G forwarders are designed to offer customizable solutions for every logging operation. The improved machine design includes a shorter frame, balanced bogie axles and rigid front axles on the six-wheeled models. The fixed or rotating and leveling cab is equipped with large windows, ergonomic armrests, a fully adjustable air-cushioned seat and automated climate-control system. Optional Intelligent Boom Control boosts productivity. Both models feature a high tractive force transmission, Adaptive Driveline Control and TimberMatic control system, and are compatible with the TimberMatic Maps and TimberManager technology offerings.
