Rigging Techniques
Various winching situations will require application of other
winching techniques. These could range from too little dis-
tance to achieve maximum pull using straight line rigging,
simply increasing pulling power, or maintaining a straight-
line pulling situation. You will have to assess what technique
is correct for your situation. Think ⬙safety⬙ at all times.
How To Change The Pulling Direction
All winching operations should have a straight line from
the winch to the object being pulled. This minimizes the
wire rope collecting on one side of the drum affecting
pulling efficiency and damaging wire rope. A snatch block,
secured to a point directly in front of the vehicle will enable
you to change your pulling direction while still allowing
the wire rope to be at 90° to wind properly onto the
spooling drum.
Increasing Pulling Power
In some cases, you may find yourself needing more pulling
power. The use of snatch blocks increases mechanical
advantage and that increases your pulling power.
