Boost your profitability with SpeedShift
Komatsu Forest is introducing a
new forwarder option, SpeedShift,
a smart solution that enables
operators to use the machine’s
full speed range without having to
stop to change gear. SpeedShift
automatically shifts the machine
up a gear as the operator increases
speed, which results in both lower
fuel consumption and higher
average transport speed.
SpeedShift is a smart gearbox
solution with dual hydrostatic
motors, with the forwarder
automatically changing up a gear
as the operator increases speed.
This enables the machine to
accelerate continuously within
the full speed range without any
additional operator intervention.
In this way, the engine can work at
optimal engine speed most of the
time, which saves fuel and provides
a quiet and more comfortable work
environment.
The automatic gear changes
enable increased transport speed
where ground conditions allow.
This can include, for example,
relatively flat access roads in
otherwise hilly terrain that can be
covered at faster speed. The longer
the forwarding roads, the greater
the benefit offered by SpeedShift.
The main difference between
SpeedShift and a standard gearbox
is the automatic gear changes. A
machine with a standard gearbox
can be driven at up to about 7
km/h in low gear; to drive faster,
the operator must stop and change
to high gear.
Since this gear changing takes
time that could be better used for
production, operators often drive
at the maximum speed possible in
low gear, which means high engine
speeds and, consequently, higher
fuel consumption.
The SpeedShift technology
is centred on a gearbox with
two motors and two operating
modes. Motors M1 and M2 are
used together when high traction
is required but the machine is
moving at low speed. When the
driving speed exceeds 6 km/h, the
gearbox automatically disengages
M2 from the powertrain. M2 is then
completely disengaged from the
hydraulic system, which means
lower energy losses and, as such,
lower fuel consumption.
The operator can adapt
the powertrain’s handling
characteristics according to needs
by switching between four driving
modes, which are selected using
buttons on the keypad. In working
modes, the accelerator pedal is
used as a driving pedal and does
not increase engine speed. In
transport mode, the accelerator
pedal instead controls the speed of
the diesel engine.
This option will initially be made
available in the Swedish market for
the 855 and 895 forwarders in 2017.
Japan and South Korea become largest wood pellet importer
Wood pellet imports to Asia
reached an all-time-high in the
4Q/16 when Japan and South Korea
together imported 630,000 tons of
pellets. Although import volumes
were down slightly in the 1Q/17,
they were still over 40% higher than
in the 1Q/16, as reported in the
latest issue of the Wood Resource
Quarterly (WRQ).
South Korea is by far the main
destination for pellets in Asia, and
in 2016, the country was the world’s
third largest importer of pellets,
trailing only the United Kingdom
and Denmark. Although import
volumes to Japan have tripled from
2014 to 2016, the usage of pellets
is still at a relatively low level (see
WRQ for detailed trade data).
Consumption of pellets in Japan
and South Korea has increased
quite rapidly the past four years
because of new government
requirements which favor reducing
carbon emissions and increasing
the usage of renewable energy.
The recent trend in pellet usageis
likely to continue in the future
and is driven both by incentives
(subsidies) and regulations
(renewable energy portfolio
standards). With an urgent need
to replace nuclear energy and
generous feed-in-tariffs, it is
expected that Japan will increase
importation of wood pellets quite
substantially over the next five
years.
Vietnam has been the major
supplier of pellets to the Asian
market for the past three years,
accounting for almost two-thirds of
the shipments to Japan and South
Korea in 2016. Canada was an early
supplier to the Asian market, but
its market share dropped from 22%
in 2014 to 14% in 2016. However,
in the 1Q/17, Canada increased
shipments to Asia to the second the
highest quarterly level on record
and the market share was up to
21%.
