Big truck clean-up
June 1st 2011 Hyster introduces Tier 4i/Stage IIIB low emission engines for its 25-32 tonne heavy
duty forklift trucks
Arange of nine models including four conventional forklift
models with between 25,000kg and 32,000kg lifting capacity
at 1,200mm load centre has been updated to Tier 4i engine
standards. The range also includes three ultra-compact models, with
wheelbases of between 3.655m and 3.935m, and two container
handlers which have a dedicated carriage for the container spreader.
The new engines are expected to deliver lower overall exhaust
emissions and fuel savings of up to 15%. The powertrain is also
said to ensure increased dependability for long periods of peak
power operation with protection for the engine and the 3-speed
transmission.
The Hyster Big Truck assembly line in Nijmegen is already
building the 25-32t range featuring the new Cummins QSB 6.7
engine (up to 270 hp, 201kW) which is said to deliver rapid
boost at low engine rpm and then maintain high boost at higher
rpm independent of engine speed. This is due to the Variable
Geometry Turbocharger (VGT) which varies the exhaust gas flow
into the turbine wheel.
In addition to the Cummins engine technologies, Hyster has
introduced cooling on demand, RPM management and alternate
engine idle speed, to help reduce the total fuel consumption.
As maximum loads are not always handled (and many lift
modes are without load), the trucks do not always require
maximum engine power and therefore less fuel will be consumed.
The operating speed of the hydraulic functions (lift, tilt,
sideshift, fork-positioners) can also be adjusted to suit the
requirements of a specific application.
Operators can also select either an ECO-eLo "fuel efficiency"
or HiP "high performance" mode. The HiP mode is the normal
operating mode, whereas the ECO-eLo mode reduces the
maximum engine speed and optimises fuel efficiency.
The trucks also have a 'dual-function' carriage. The hook-style
design with a 'quick-disconnect' (dis)mounting feature for the
forks enables fast exchange between forks and attachments such
as coil rams. Sideshift and fork-positioning functions are featured
as standard, and include two fork-positioning working ranges.
The masts offer heavy lifts up to 6.20m high.
For the operator, the Hyster 'Vista' operator compartment
provides the operator with a cab that is positioned mid-high and
towards the front.
Maintenance requirements are kept to a minimum with features
such as oil-immersed brakes and increased service intervals are
promised, contributing to lower overall operating costs. The tilting
cab, which ensures easy access to key components, also makes
servicing easier.
Antoon Cooijmans, big trucks product manager for Hyster
Europe said: "The trucks are all intelligently designed to offer a
unique blend of high productivity, reliable proven components,
fuel efficiency and outstanding driver comfort for intense use in
ports or in heavy industry. The 25-32 tonne range is packed with
features to reduce energy consumption and save fuel and helps
drivers maintain comfort and concentration throughout a shift.
"We have also made Tier4i/Stage IIIB compliance easy for the
operator by using EGR engine technology, which means that the
end user does not have to change the way it operates. Diesel is
added to the tank in exactly the same way and the engine does
the rest with no additional equipment, additives or maintenance
regimes, unlike SCR technology.
The company's range of reach stackers has also been redesigned
with Tier 4 interim(i), Stage IIIB emissions regulations in mind.
Hyster believes that, in certain intensive operations, the redesigned
machines can deliver fuel savings of up to 23%.
Low emissions are achieved across the larger models in the
Hyster Big Truck range using the new Cummins QSL9 (up to 370
hp, 276kW) engine. Combining cooled exhaust gas recirculation
(EGR) with an improved High Pressure Common Rail (HPCR)
fuel system enables more efficient combustion, and effectively
controls NOx emissions. The integrated Cummins Diesel
Particulate Filter (DPF) also
reduces particulate emissions. More articles from Hyster Europe: |
