3.2
Anchoring the winch.
OPTION
1
:
In
most
cases,
the
winch
is
anchored
to
a
fixed
object
using
a
polyester
sling
or
one
of
our
optional
anchors
and
the
line
is
attached
to
the
object
you
are
trying
to
move.
The
latter
is
moved
towards
the
winch
as
the
winch
pulls
the
line.
OPTION
2
:
Sometimes,
the
winch
can
be
anchored
to
the
object
you
want
to
move
and
the
line
is
attached
to
a
fixed
object.
The
winch
and
the
object
being
moved
are
then
pulled
towards
the
line's
anchoring
point.
This
method
is
useful
when
you
guide
the
load
while
operating
the
winch.
Your
winch
is
supplied
with
a
polyester
sling.
To
anchor
the
winch,
wind
it
around
the
anchoring
point
with
the
sling.
Insert
the
sling
in
each
of
the
two
safety
hooks
located
on
the
back
of
the
winch
(fig.1).
Place the winch in the direction of the load to be pulled. When the
winch is switched on, it will attempt to align itself with the load. The
friction of the sling against the anchor may prevent correct
alignment; in this case, release the tension in the line and move the
sling so that the tension is distributed over the two hooks equally.
We also offer a wide range of anchoring accessories for our
capstan winches. Visit

3.4
Installing the rope.
The wide range of situations encountered during pulling prevents
us from giving specific instructions for all situations; however, you
should consider the following points:
3.4.1
Rope.
Use a line with a low elasticity in good condition with a minimum
diameter of 10 mm and a maximum diameter of 12 -13 mm with
good knots. We highly recommend the bowline knot (see section
3.1.3). Use pulleys to divert the line and increase the pulling power
when the load approaches or exceeds the winch's pulling capacity.
3.4.2
Pulley.
The use of a pulley at a short-distance from the winch offers several
benefits:
●
Provides an angle allowing the load to be slightly raised to
reduce friction;
●
Maintains the winch in near horizontal position;
●
Keeps the winch and the operator away from the load's
trajectory.
3.4.3
Direction.
Install the line so that it doesn't rub against any objects during
pulling. Try to install the line so that the front of the load is slightly
raised.
Never
pull
downwards
or
through
obstacles.
WHAT NOT TO DO
: WHEN YOU INSTALL THE SLING TO
ANCHOR THE WINCH, AVOID A FULL TURN AROUND
AN ANCHORING POINT (FIG, 2). THIS WILL PREVENT THE
WINCH FROM ALIGNING ITSELF WITH THE LOAD
CORRECTLY. THIS WILL ALSO APPLY UNEVEN TENSION
TO EACH OF THE HOOKS.
AVOID INSTALLING THE SLING ON SHARP CORNERS
WHICH ARE LIKELY TO DAMAGE THE POLYESTER SLING.
WHEN YOU USE A POLE, A TREE OR A STUMP AS AN
ANCHORING POINT, INSTALL THE SLING CLOSE TO THE
BASE.
ANCHORING AROUND A STUMP REQUIRES SPECIAL
ATTENTION TO AVOID THE SLING SLIPPING OFF THE TOP
OF THE STUMP.
ENSURE THAT THE ANCHORING POINT IS ABLE TO
WITHSTAND THE WINCHING WITHOUT BREAKING, BEING
EXTRACTED OR BECOMING DAMAGED.
You must attach the load to the
end of the line. Although a
simple knot may sometimes
suffice, we recommend using a
bowline knot (fig. 1). This knot
holds approximately 70% of the
line's capacity while most knots
reduce the line's capacity by
50% or more. Additionally, it
may be easy to untie even after
pulling a heavy load.
Even better, a double bowline
knot (fig. 2) allows you to
maintain approx. 75% of the
line’s capacity.

1
PERFORM A VISUAL INSPECTION OF THE LINE BEFORE
EACH USE. IF IT SHOWS OBVIOUS SIGNS OF WEAR
(STRANDS
CUT,
EXCESSIVE
ABRASION)
THEN CHANGE IT.
IF YOUR LINE IS DIRTY, CLEAN IT. A DIRTY LINE CAN
QUICKLY
BECOME
DAMAGED
AND
CAUSE
PREMATURE WEAR OF PARTS WHICH COME INTO
CONTACT WITH IT.

THE CORRECT DIRECTION WHEN DEPLOYING THE LINE
IS THE KEY TO THE SAFE USE OF THE WINCH.
IN GENERAL, IF THE LINE TOUCHES THE GROUND
DURING PULLING THEN THE SETUP IS INCORRECT.
