Tigercat competes in three
forwarder classes: the 1055C is a
14 t capacity machine; the 1075C is
a 20 t forwarder and the 1085C is
rated to carry a massive 25 t load.
The new C-series forwarders are all
powered by the Tigercat FPT N67
engine with either Tier 4f or Tier 2
configurations.
The 1055C now offers Tigercat’s
innovative ‘low-wide’ bunk system
and ‘WideRange’ drive. The 1055C
is also available with a choice of
three wagon frame lengths and
fixed bunks. The new Tigercat
F135T85 hooked crane means more
lift for the 1055C and less chance of
the crane contacting the gate.
1075C is designed for long-
distance forwarding, steep
slopes, scarifying and other tough
applications. With heavy duty
wide spread bogies, the 1075C
excels in tough terrain and slopes
and operates with minimal soil
disturbance.
The expandable bunk improves
productivity by increasing payload
in applications where the wood is
relatively light in weight and load
area is the constraining factor. With
a reliable two-speed transmission,
the 1075C is also the best choice
when extensive roading is required
for the application.
The 1085C excels in “severe
duty” applications and is
especially well matched to steep
slopes. This model is equipped
with the extreme duty Tigercat
engineered and manufactured
ROB17 bogies and Tigercat
the WideRange transmission.
The Tigercat designed and
manufactured driveline provides
tractive effort that is “unmatched
in the industry”, according to the
manufacturer.
WideRange transmission
The 1055C and 1085C both use
Tigercat’s WideRange transmission.
WideRange is an infinitely variable,
single speed transmission
well-proven in extreme forestry
applications.
For the 1085C, WideRange
allows for extremely high tractive
effort while achieving a maximum
working speed of 7 km/hr.
Hooked-crane profile and low-
wide bunks
Tigercat’s innovative hooked
cranes are now available on all
three forwarder models and
include standard end-of-position
dampening sensors on the
stick boom and slew bearing to
prevent impact loads. The tapered
roller bearing in the slew base
is designed to last the life of the
machine, an improvement over the
plain bearing and spherical rollers
used in other cranes.
The crane’s hooked profile
increases the working envelope
of the crane for reduced machine
travel and improved productivity.
“The crane really shines when
used in combination with Tigercat’s
low-wide expandable bunk
systems,” Tigercat stated.
The low-wide bunks are angled
to reduce overall gate height and
eliminate the need for a vertically
sliding gate. In combination with
the hooked crane, the low-wide
bunk system significantly reduces
the chance of contact with the gate
or bunk stakes.
The operator enjoys a clear
sightline to the top of the load,
increasing log placement accuracy
and decreasing cycle times. In
addition, the grapple stays within
the operator’s view through the
entire loading and unloading cycle
for reduced operator strain. The
low-wide system is available for all
Tigercat forwarders.
Tigercat grapples
Since an average of 50% of
the forwarder duty cycle is
spent loading and unloading,
increasing the number of logs
per crane cycle is another way
that Tigercat is improving overall
machine productivity and reducing
forwarding cost per tonne.
The FG43 and FG53 series
Tigercat grapples available on the
1075C and 1085C complement the
powerful cranes with larger load
area capacities of 0.43 m2 (4.6 ft2)
and 0.53 m2 (5.7 ft2) respectively.
The grapples are fitted with
thick walled bushings for extended
service life. The link has a patent
pending hose routing design
to better protect the hoses and
the swing dampener has been
designed for heavy duty.
The tilt out hood enclosure on all
Tigercat C-series forwarders makes for
simple access to the Tigercat FPT N67
engine for regular servicing
