Hyster gets tough on forklift, reachstacker and container handler engine size

“Bigger is no longer better when it comes to engines” says Jan-Willem van den Brand, product strategy manager for Hyster Big Trucks.

Hyster recently made a bold move by introducing new Tier 4i / Stage IIIB compliant engines and new system technologies across its complete range of Big Trucks with over 16 tonnes lifting capacity.

“Big Truck users at ports and in heavy industries want tough, powerful equipment, but they also want reduced fuel bills” he says, explaining that in the EU and North America, businesses must comply with strict environmental regulations.  “The new breed of Hyster Big Trucks features the right size engines that provide high performance and significant fuel savings in the region of 15%.”

“For our 25-32 tonne forklifts we replaced the Tier 3 QSC 8.3 litre engine rated at 260hp with the Tier 4i /Stage IIIB QSB 6.7 litre rated at 270hp. For the Reachstacker, laden container handlers and 36-48t forklifts we replaced the Tier 3 QSM 11 rated 300 or 335hp by the QSL 9 rated 350Hp. The performance of the trucks has improved while fuel consumption has been significantly reduced.

"This high performance is thanks to a strong working partnership with engine supplier Cummins and the introduction of features such as the Variable Geometry Turbocharger (VGT™), and XPI (High Pressure Injection system). The transient response of these engines is so much better now, it opened up new possibilities and we took advantage of it" Jan-Willem says.

Hyster has addressed how the power produced by the engine is used most efficiently in each truck function, by introducing new performance optimisation features such as cooling on demand, load sensing  hydraulics, RPM management and alternate engine idle speed.

In order to optimise truck performance in the application, performance settings can be adjusted - the HiP “high performance” mode is the standard operating mode, delivering maximum productivity or the ECO-eLo mode can be selected, which reduces the maximum engine speed and optimises fuel efficiency further.

“The powerful trucks are also cleaner and quieter in operation than ever before.  Exhaust emissions are low and cleaner and more efficient combustion, with reduced NOx emissions, is possible thanks to the combination of cooled exhaust gas recirculation (EGR) with an improved High Pressure Common Rail (HPCR) fuel system.  The fully integrated Cummins Diesel Particulate Filter (DPF) also reduces particulate emissions by over 90%.

"Furthermore, operators can fill the fuel tank in the same way, without the need for any additional processes or chemicals” he says.

Featuring engine and transmission protection systems, Hyster ensures excellent reliability in the most demanding operations everywhere.
