2.7 Winching Principles
2.7.1 Pulling Angle
Locate a suitable anchor such as a strong tree
trunk or boulder. Always use a sling as an anchor
point.
CAUTION
DO NOT attach the clevis hook back onto the
cable as this could cause damage to the cable.
Figure 13.
CAUTION
DO NOT winch from an acute angle as the
wire rope will pile up on one side of the drum
causing damage to wire/synthetic rope and the
winch. Figure 14.
Short pulls from an angle can be used to straight-
en the vehicle. Long pulls should be done with
the wire rope at a 90° angle to the winch/vehicle.
2.7.2 Recovery Damper
A recovery damper is a safety device designed
to help reduce the possibility of injury or property
damage in the event of a wire/synthetic rope
failure. A blanket or heavy jacket are acceptable
substitutes for the damper. Place 5-6 feet from
hook. Figure 15.
2.7.3 Snatch Block
For pulls over 70% rated line pull, we recom-
mend the use of the snatch block/pulley block to
double line the wire/synthetic rope. Figure 16.
An important aid to successful winching is the
use of snatch block, which can be used to
increase the pulling power of a winch or change
the direction of a pull.
A winch double lined with a snatch block creates
a mechanical leverage cutting the effort required
by nearly half.
The use of one snatch block shows an indirect
pull where the vehicle is limited due to unsuitable
ground or obstruction. The pull on the load is
the actual line pull of the winch. If more than one
snatch block is used, they must be located at
least 40" (100 cm) apart. Figure 16.
