Hyster has introduced its new generation of forklifts, container handlers, and reach stackers that are said to achieve up to 15% improved fuel efficiency. The 16- to 48-t (18- to 53-ton) capacity Hyster Big Truck range features Cummins QSL9 and QSB6.7 engines with an integrated air-intake-to-exhaust aftertreatment system meeting U.S. EPA Tier 4 Interim and EU Stage IIIB regulations taking effect Jan. 1. The trucks provide the same lift capacity, lift speed, and travel speed as the equivalent Tier 3/Stage IIIA trucks with larger-displacement engines. Collaboration between Hyster and Cummins application engineers enabled highly efficient engine calibrations aligned with the new ECO-eLo “fuel efficiency” or HiP “high performance” truck operating modes. Performance optimization work by Hyster, such as cooling on demand and load-sensing hydraulics, has helped realize the full potential of the Tier 4 technology, according to Cummins—the exclusive engine partner for the Hyster Big Truck range. The Cummins Particulate Filter removes over 95% of all particulate-matter emissions from the exhaust. Field test work with Hyster demonstrated that the filter operates up to 99% of the time in passive regeneration mode; when active regeneration is required, it does not affect lift truck operation, Cummins claims.
