12F GTs were performing on 80 %
slopes.
- This option is really
recommended if you constantly
need to forward or skid on slopes
and are looking for maximum
efficiency. Since the TWinch
assistant has its own engine,
it doesn’t take power from the
operating machine, Kivipelto
mentions.

In Chile, Biofor is using a Logset clambunk, with which they can pull the
whole stems from the slopes. The size of the clambunk is 2,75 m2.
Slopes are challenging terrains
within the forest industry, as
forest machines are heavy and
may damage the ground surface.
Luckily, there have been constant
advances in forest machine
technology and today solutions
exist for collecting timber on steep
slopes.
In South America, Logset
has tested a separate winch on
forwarders with great results.
- If the machine works daily
in slopes, I would recommend
the separate TWinch assistant
developed by Ecoforst. We have
used their solutions with our
biggest forwarder Logset 12F GT
in South America with impressive
results, says Logset’s Technical
Director Jukka Kivipelto and
continues:
- The TWinch makes the
machine more versatile, because
the cable can be either attached
to the front or rear of the chassis.
The T-Winch can also easily be
transferred to another pulling spot
by remote control.
always stays tight and secure,
Kivipelto explains.
The Logset 12F GT forwarder
has a tractive effort of 250 kN.
Combined with the T-Winch’s
pulling power, the machine
operator has 350 kN of tractive
power available. The 12F GT combo
can operate safely on a regular 45

Maximum power and
efficiency with a t-winch
Logset delivered 12F GT forwarders
with clambunk configuration to
Biofor in Chile in mid-2016. Their
work sites are exclusively clear
fells. On the hills, the weight
distribution among the eight
wheels is uneven and therefore the
T-Winch is of a great assistance.
- The synchronized TWinch is
automatically connected to the
operating machine through radio
control. For example, if the driver
of the machine stops, the T-Winch
also stops. This way the cable
