2.7 Winching Principles
2.7.1 Calculating fleet Angle
CAUTION
To obtain the best wire rope service, the direction of pull will be
on a horizontal within ±15 degrees and perpendicular to the cen-
terline of the winch drum within ±5 degrees. Short pulls of up to
45 degrees laterally are acceptable; however without maintaining
the proper fleet angle; the rope will pile onto one side of the rope
drum and possibly do damage to the rope or winch. Re-spool
your winch as required. Figure 18
2.7.2 Recovery Damper
WARNING
A recovery damper is a safety device designed to help reduce
the possibility of injury or property damage in the event of a
wire rope failure. Place in the middle third of a live rope.
Figure 19.
2.7.3 Snatch Block
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 20.
