Hyster’s Big Trucks Reach Tier 4 Final Compliance | Industry News

Hyster Company has launched its first Tier 4 Final-compliant big truck models with fuel savings of up to 25%. “Building on the operational success of our Tier 4 Interim products, we’ve been able to achieve even greater fuel savings for our 2014 models, reducing the total cost of ownership while meeting the new emission regulations,” said Brett Schemerhorn, president of big trucks for Hyster Company.

Hyster 40,000- to 70,000-lb. trucks and empty container handlers now feature a Tier 4 Final Cummins QSB 6.7L engine with a ZF WG 211 5-speed powershift transmission. The engine offers peak power of 230 hp for the H400-450HD/S and empty container handler models and 270 hp for the H550-700HD/S models. Hyster’s 80,000- to 105,000-lb. trucks and ReachStackers including the H1050-1150HD-CH laden container handlers, now come standard with a Tier 4 Final Cummins QSL 9L engine with peak power of 363 hp with a Dana Spicer Off-Highway TE 32 powershift transmission.

The integrated drivetrain with emission reduction package includes cooled exhaust gas recirculation (EGR), a selective catalytic reduction (SCR) system for nitrogen oxide (NO_X) reduction, a diesel oxidation catalyst (DOC) for particulate matter removal and a diesel exhaust fluid (DEF) delivery system. This package results in approximately 96% less particles (soot) and 94% less NOx compared to Tier 3 equivalents built before 2005. It requires no diesel particulate filter (DPF), no extra operator intervention and no ash cleaning service.

In addition to the Tier 4 Final Cummins engine technology, Hyster big truck performance optimization developments such as ECO-eLo mode, cooling on demand, RPM management and alternate engine idle speed, help further reduce total fuel consumption.
