Ports and terminals could reduce container handling and reachstacker fuel consumption by 25pc. This was the message from Hyster at an exclusive press event in Nijmegen, the Netherlands, where the company reported on data collected from customers who have switched to using its latest super low emissions Stage IV / Tier 4final (T4f) compliant Big Trucks.
“We now have up to 25pc fuel savings on our 2015 models, without loss of performance, compared to Stage IIIA 2010 trucks and many of our competitors,” says Jan Willem van den Brand, Product Strategy Manager Big Trucks, at a press conference at the factory where the 1000th Hyster® ReachStacker had just come off the production line.
“The latest Hyster ReachStackers and Container Handlers, used to transfer and stack shipping containers, have proven time and again to offer significant fuel savings,” says Jan Willem. “We had the first Stage IV / T4f test trucks running back in May 2012 and have since collected thousands of validation hours in real life applications.
“We have ‘right sized’ the engines to give the best performance, reliability and economy," he says. “Our goal was to continue our 'Profitable Low Emissions' strategy reducing the total cost of operations and ownership while meeting the new standards for a cleaner environment.”
The latest Hyster Big Trucks above 18t lifting capacity feature EGR (Exhaust Gas Recirculation), DOC (Diesel Oxidation Catalyst) and SCR (Selective Catalytic Reduction) technologies to meet the Stage IV / T4f legislation.
As featured on the 1000th Hyster ReachStacker, the Cummins QSL9 (up to 370 hp, 276kW) provides the power, which is also used on the Hyster 36-48t forklift trucks, and Hyster laden container handlers. The Hyster 5-8 high empty container handler, the 18-20t and 25-32t forklift truck ranges feature the latest Cummins QSB 6.7 engine (up to 270 hp, 201kW) with similar benefits.
The engine's EGR technology reduces NOx (nitric oxide and nitrogen dioxide) formation during combustion, preventing the majority of the NOx formation, followed by SCR, which removes the remaining NOx from the exhaust stream. This provides the best possible control of NOx at all engine loads and exhaust temperatures allowing fully optimised power and response and low fuel consumption. This combination requires low DEF (Diesel Exhaust Fluid) usage with no risk of crystallisation.
For PM (particulate matter) reduction, high pressure fuel injection reduces PM formation at source and a diesel oxidation catalyst (DOC) removes remaining PM from the exhaust stream. There is no DPF (diesel particulate filter), no additional operator intervention or ash cleaning service required. In addition, the DOC increases the exhaust temperature allowing normal idle rpm.
“EGR and DOC allow a controlled burn,” Jan Willem says. “With a smaller block size, a larger power range can be achieved.”
In addition to the Cummins engine technologies, further Hyster performance optimisation includes cooling on demand, load sensing hydraulics (power on demand), RPM management and alternate engine idle speed to help further reduce the total fuel usage.
The trucks also feature the ECO-eLo Fuel Efficiency Mode, which can be used to reduce the maximum engine speed and further optimise fuel efficiency. With engine, transmission and hydraulic protection systems, Hyster ensures excellent reliability in the most challenging quayside operations and has proven performance results.
A selection of previous Hyster models is still available for sale to regions outside of the EU and North America and all Hyster equipment is supported worldwide by a global network of local distribution partners.
