WARN INDUSTRIES • THE BASIC GUIDE TO WINCHING TECHNIQUES
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. 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 90º 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:
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 and run the wire rope through a snatch block. Do not attach hook to mounting kit.
Disengage the clutch and, using the
snatch block, pull out enough wire to reach your 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).
Single line Double line
Step 17:
DISCONNECT WIRE ROPE.
Disconnect from the anchor. Step 18:
REWIND WIRE ROPE.
The
person handling the wire rope should walk the rope in and not let it slide through the hand and control the winch at all times.
How to spool under no load
Arrange the wire rope so it will not kink or
tangle when spooled. Be sure any wire rope already on the spooling drum is wound tightly and evenly layered. Tighten and straighten the layer if necessary. Keep the wire rope under
light tension and spool the wire rope back onto the winch drum in even layers one layer at a time. At the end of each layer stop spooling and arrange the wire rope in tight even layers.
Repeat this process until the winch hook is a minimum of 4 ft. (1.2m) from the
winch. Pinch the hook between your thumb and forefinger and attach the hook strap. Hold the hook strap between the thumb and forefinger to keep tension on the wire rope. Walk the wire rope towards the fairlead, carefully spooling in the remaining wire rope by pulsing the control switch. Store the hook at the fairlead or tensioned to a suitable location to the side.
If you do not have the hook strap, use a length of cord or something similar.
To prevent serious injury, NEVER put your fingers inside the hook area as you are powering in.
Step 19:
DISCONNECT REMOTE
CONTROL.
Disconnect the remote
control cord and store in a clean and dry place. Winching operations are now complete. Put the cap on the solenoid plug in.
Always keep hands and clothing clear of the wire rope, hook and fairlead opening during opera- tion and when spooling.
