Hyster Co., Greenville, N.C., has launched a new generation of forklifts, container handlers and reachstackers with low emissions power from Cummins Inc., achieving up to 15 percent improved fuel efficiency. The 16-48 tonne capacity Hyster ‘Big Truck' range features Cummins QSL9 and QSB6.7 engines with an integrated air-intake-to-exhaust after-treatment system, meeting U.S. EPA Tier 4 Interim and EU Stage IIIB regulations taking effect Jan. 1, 2011.
While achieving a major reduction in fuel consumption and a lower carbon footprint, the QSL9- and QSB6.7-powered trucks provide the same lift capacity, lift speed and travel speed as the equivalent Tier 3/Stage IIIA trucks with larger displacement engines. Advancements in power density and productivity are realized due to Tier 4 technology enhancements, including Cummins Variable Geometry Turbocharger (VGT), which enables faster transient response across the rpm band. Cleaner, more efficient combustion is delivered by Cummins Xtra-High Pressure Injection (XPI) on the QSL9 engine and High Pressure Common Rail (HPCR) fuel system on the QSB6.7 engine.
Peak power output for the QSL9-powered Hyster trucks is 370 hp (276 kW) and 270 hp (201 kW) for the QSB6.7-powered trucks. Close collaboration between Hyster and Cummins application engineers has resulted in highly efficient engine calibrations aligned with the new ECO-eLo "fuel efficiency" or HiP "high performance" truck operating modes.
