CARGO HANDLING
Mast trucks headed for the US
compliant engines to the US, or vice versa,
unless dual certification is obtained.
Hyster says it is the only lift truck builder
that has certified all its products under
both EU and EPA regimes, so trucks can
be freely shipped both ways.
The division into emission zones raises
other interesting points. Cummins, for instance,
states that Stage IIIb/T4i engines
operated outside their intended emission
region “will not carry a warranty.” This
reticence is based on the availability of
ultra-low sulphur diesel fuel (ULSD).
Stage IIIb/Tier 4i engines must operate
on fuel with a sulphur content no greater
than 15ppm and preferably ≤ 10ppm. This
is readily available in Europe and the US,
but can be scarce in some other regions.

has not yet adopted Stage IIIb/Tier 4i or
equivalent. However, it has wide sources
of ULSD and accordingly the Cummins
warranty holds.

Final stage
The next and final emission regulations,
due in January 2014, do not represent such
a major engineering challenge as did the
switch from Stage IIIa/T3, in Hyster’s
view, as much of the work has already
been done, particularly the incorporation
of greater cooling capacity.
Hyster has been working in conjunction
with Cummins for two years on the
Stage IV/Tier 4 final project, with two
machines currently on field tests. Instead
of Cummins developing a solution that
is then tested in a truck, both engine and
machine tests are being carried out in parallel
under all load conditions.
Hyster is not yet in a position to release
details of what the final configuration
will be, but it is interesting to note
that at this year’s Bauma, Cummins unveiled
a Stage IV/T4f solution incorporating
an ultra-clean aftertreatment system,
combining the Cummins Compact
Catalyst with Selective Catalytic Reduction
(CCC-SCR). This will be employed
in the QSL9, QSB6.7, QSB4.5 and
QSB3.3 engines to offer a common
aftertreatment solution from 75hp to
400hp. Operators can also expect a 2-3%
fuel efficiency gain from T4i to T4f.
The SCR system developed by
Cummins for Stage IV/T4f is described
as a “next-generation design that moves
beyond SCR technology currently in use
for T4i.” The system incorporates a copper
zeolite-based catalyst capable of up
to 95% absorption. Through passively
oxidising PM from the exhaust stream,
the CCC is a maintenance-free “fit and
forget” device. It involves dosing the engine,
albeit in smaller quantities than for
T4i/Stage IIIb SCR, with Adblue/DEF
- something that Hyster has avoided up
to now by staying with Cummins cooled
EGR and a diesel particulate filter.
The real touches
While a lift truck manufacturer is an assembler
of other suppliers for its key components
- engines, gearboxes, axles, attachments,
hydraulics - the strength of the
brand is how these can be put together
to gain the greatest advantage, while at
the same time developing specific subsystems
to lower the cost of ownership.
One feature Hyster is set to introduce
across it full range fitted with CanBus
systems is a performance data tracking
system. This comprises three modular levels,
with the basic level being a passive
reporting system covering hour meter,
cost of operation, periodic maintenance,
fault code tracking, impact sensing and
operator training. The Hyster Tracker
monitors the materials handling fleet,
controls operator access and helps to
verify that the operator completes his preshift
checklist before starting.
Accessing the cab
The second level, wireless access, includes
operator access restrictions and driver
identification using a swipe card, which
could also be used for checking onto the
shift. This feature is also useful for rental
trucks, where the swipe card can be preloaded
with the rental period. When this
is exceeded, the truck is immobilised. If
an impact occurs, emails are sent out automatically,
making it easier to review
incidents and related product damage.
The wireless access offering enables
remote monitoring, and idle shutdown.
To prevent operators leaving running
equipment unattended, an idle shutdown
feature powers off the truck following a
pre-set amount of time if the equipment
is tracked as idling or unattended. This
also helps to reduce excess fuel costs.
The Hyster Tracker Wireless Access
Managment System will be available later
in the year in EMEA based on either WiFi
or GPRS communications over local mobile
phone coverage, and will be accessed
through the HysterTracker.com portal. ❏
