After many years of successes, the Sherpa dual-track snowmobile is still the only snowmobile which can truly be considered a work-horse. The twin-track of 500+500 mm width provide an unbeaten capacity of floating over fresh snow, together with a superior traction and stability. Driving the Sherpa is extremely handy and easy, even in narrow trails and corners, thanks to the twin-skis steering system with its unique design. Since its first launch, the Sherpa is still the only snowmobile with catalytic converter in conformity with European and the EPA automotive emissions standards.
The
2012 version of the Sherpa is equipped with a silent engine 1.6 liters 4-stroke
with variable camshaft timing (VCT) provides plenty of torque (155 Nm. / 114
ft-lbs.) and power (115 Hp @ 6000 rpm.), as well as a great fuel economy and
a cheap maintenance-routine.
The new "second-generation" ATSS track-suspension can be adjusted to vary
the load on the rear part of the tracks, thus adapting the trim to every specific
situation.
The new track design, with a 32 mm height aggressive profile lug, improves
grip and traction on any type of snow.
The slight body-restyling was mostly focused on the front air intakes, head-lights
and tail-lights and some minor details.
A
new innovative accessory introduced by Alpina is the SRK (Safe Rescue
Kit), an equipment designed for the rescue of injured persons in ski-areas.
The new SRK introduces a whole new safety-standard among the rescue-equipments.
The Sherpa dual-track snowmobile is everywhere recognized as the safest and
most stable snowmobile in the market and, thanks to these features, the SRK
is an accessory specially designed to be installed directly on it.
The special stretcher is installed transverse-way over the rear cargo-platform.
It can accommodate the injured patient on either a vacuum-mattress or a backboard,
and it is provided with a special absorbing system to prevent vibrations and
shocks to the patient even if in case of severe spinal-trauma (it is the typical
injury that in the past required the support of an helicopter to face it).
The SRK has an electronic-system which keeps the stretcher in horizontal position
during all the hill descent, independently by the inclination of the snowmobile,
increasing the comfort and the safety of the patient. The stretcher is protected
by a roll-over guard (ROPS) and a sturdy perimetrical frame integrated with
the stretcher. The SRK has a dual ski-rack able to carry the patient's and
the rescue-team's skis, and is complete of warning signals (optical and acoustic)
to increase visibility in the slopes during the whole rescue operation. The
kit can be easily and quickly installed and removed from the Sherpa, allowing
to use the Sherpa for any other purpose (grooming, transporting people and
goods, etc) when the rescue service is not needed. Thanks to the SRK, any
rescue-teams will finally have a safe, quick and effective rescue machine
specially designed for this purpose. According to the several tests made in
cooperation with professional rescue-teams, the SRK's performances are above
any other rescue-device (i.e.: the traditional toboggans behind-skier or behind
snowmobiles).
For the people transportation the Sherpa equipped with the 3-seats kit can carry 3 more passengers on the cargo-platform (plus one passenger and the driver on the seat), for a total of 5 persons. In addition, the towing-sled Transalp BUS can accommodate 6 / 9 persons, that means up to 13 passengers plus the driver. The roll-over protections (ROPS) and the safety belts, together with the frame's design and the special ski-suspensions, make the Transalp BUS the safest and most effective among all the existing personnel transportation systems. A new accessory for the Transalp BUS towing-sled is also available: a full-transparent weather-shield including windshield and roof. This "all-weather" shield will protect the passengers from snow, wind and cold, without any limit to the field of vision, since the shields are transparent. The Transalp towing-sled can be easily converted into a sled for transporting any type of materials, with a payload capacity over 830 Kgs. / 1830 lbs.
Cross-country
ski is one of the favourite applications of Alpina, and the new version of
the track-making equipment "F-One" is the state-of-the-art of technology
for perfect cross-country ski tracks. The F-One system was born to give Sherpa
the capability of making ski-tracks with the same quality offered by a snow-cat,
setting both the classic-track and the skating-lane with a 2.500 mm width.
The track-maker with variable ski-distance includes a power-tiller with on-board
4-stroke engine and hydraulic-transmission. The engine has a control-panel
with hour-meter and warning-lights; all the controls and functions are activated
through a keyboard installed on the Sherpa, and connected to the F-One with
a can-bus wiring. The skating lane is set by a 74-knives tool and a finisher-comb
with a special profile, different by the standard alpine-ski profile: the
F-One comb is finer and with an higher number of teeth, less aggressive and
more suitable for the modern cross-country ski.
In December 2011 Alpina will also unveil the new F-250, an innovative grooming/trackmaking
accessory for the Sherpa series. The new F-250 system is fully operated
through electric actuators, controlled by a smart can-bus keyboard from the
snowmobile cockpit. It will be available with one or two track-setters equipped
with on-board electric grooming stage instead of the traditional rotor powered
by gasoline engine through hydraulics.
The F-250 will make the Sherpa an indispensable machine for all the XC-ski
areas who keep a particular eye on environment, functionality and economy.
