Hyster has launched its first Tier 4 Final emission compliant big truck models in the United States, with the company tipping fuel savings of up to 25 percent from the high-capacity forklift trucks and container handlers.

Hyster's H400-450HD/S high-capacity forklift truck.

The company says its aggressive move toward Tier 4 Final compliance is the result of the United States Environmental Protection Agency (EPA) requiring additional emission reductions over Tier 4 Interim products.

"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," Hyster Company President, Big Trucks, Brett Schemerhorn says.

Aimed at demanding ports, terminals and heavy industry, the 18-tonne to 32-tonne trucks and empty container handlers now feature a Tier 4 Final Cummins QSB 6.7L engine with a ZF WG 211 five-speed powershift transmission.

The engine offers peak power of 172kW for the H400-450HD/S (pictured) and empty container handler models; and 200kW for the H550-700HD/S models.

Hyster’s 36-tonne to 48-tonne 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 271kW 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 (NOX) reduction, a diesel oxidation catalyst (DOC) for particulate matter removal and a diesel exhaust fluid (DEF) delivery system.

This package results in approximately 96 percent fewer particles (soot) and 94 percent 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 says its big truck performance optimisation developments such as ECO-eLo mode, cooling on demand, RPM management and alternate engine idle speed, help further reduce total fuel consumption.
