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 collect ing
on one side of the drum
affecting pulling efficiency
and damag ing wire rope. A
snatch block, secured to a
point directly in front of the
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:
vehicle, will enable you to change your
pulling direction while still allowing the
wire rope to be at 90º to wind properly
onto the spooling drum.
Various winching situations
will require application of
other winching techniques.
These could range from too
little distance 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.
RIGGING TECHNIQUES
WARN INDUSTRIES • THE BASIC GUIDE TO WINCHING TECHNIQUES
Triple Line
Use the same techniques as the
Double Line. Select a robust mounting
location on your vehicle for the snatch
block and the screw-pin shackle. Keep a
90º angle between the winch and run
the wire rope to the first anchor-point
and through the snatch block. Secure
rope back to the vehicle. Put the wire
rope through the snatch block and
secure with the screw-pin shackle on the
vehicle as close to the winch as practical.
Now run the wire rope to the final anchor
point.
Secure to the anchor point with a tree
trunk protector or choker chain. Attach
the clevis/shackle. Attach the shackle to
the two ends of the strap/chain, being
careful not to over tighten (tighten and
back-off 1/2 turn).
Secure the winch hook. While
keeping the line near the ground, insert
the winch hook through the screw-pin
shackle. Check your anchor. Make sure all
connections are secured and free of debris
before continuing with the winching
procedure.
Double line
Because pulling power decreases with
the number of layers of wire rope on the
winch drum, you can use a snatch block
to double line out more wire rope. This
decreases the number of layers of wire
rope on the drum, and increases pulling
power.
Start by feeding out enough wire rope
to free the winch hook. Attach the hook
to your vehicle’s frame/tow hook and run
the wire rope through a snatch block.
Disengage the clutch and, using the
snatch block, pull out enough wire to
reach your anchor point. Do not attach
hook to mounting kit.
Secure to the anchor point with a tree
trunk protector or choker chain. Attach
the clevis/shackle. Attach the shackle to
the two ends of the strap/chain, being
careful not to over tighten (tighten and
back-off
1/2 turn).
