CAN in hydraulics for forestry machinery with Tier 4
Source: CAN Newsletter December 2010
Mobile hydraulics components and system solutions from Bosch Rexroth are designed for the new Tier 4 final emission regulations (to be phased-in from 2008 to 2015). They reduce diesel fuel consumption and emissions in mobile work equipment used in the forestry industry. The BlueHydraulics technologies introduced at Interforst 2010 in Munich, Germany compensate for the expected power losses in Tier 4 final engines without sacrificing the accustomed machine performance and handling capacity. The brake systems increase safety and comfort in rough terrain.
Solutions
The DHC (diesel hydraulic control) features digital networking of the travel drive and implement hydraulics with the diesel engine ECU (engine control unit) to realize fuel consumption savings of up to 20 % with correspondingly reduced harmful emissions. DHC enables lower consumption while maintaining the accustomed dynamic response in complex motion with multiple actuators. The diminished engine output resulting from downsizing concepts and lowered engine speeds is thereby compensated.
