Tech Tip Tuesday: Double-line = Double Power

If you’ve ever been stuck—really stuck—you’ll know that sometimes a single-line pull just won’t cut it. You need more power to get yourself out of the situation. A double-line pull might be just the thing.

WARN Epic Snatch Block

We’ve talked about how the more rope you pull out, the more power you have since the winch’s maximum pulling capacity is at the last layer of rope, but sometimes that’s still not enough. In this case, you’ll need to perform the double-line pull. To perform a double line pull, you will have to use a snatch block (essentially a pulley) and a shackle to attach the snatch block to a suitable anchor.

For example, in the photo above, we’ve got a stuck Jeep Cherokee that needs to be pulled out of the ditch. To demonstrate the double-line pull, we’ve run the winch rope out to a snatch block which is attached to a shackle receiver bracket on the back of the Jeep as an anchor. The winch line passes through the block, and returns to a recovery point on the front of the truck. This is a double-line pull and will provide more power (but less lines speed) for the recovery.

The same thing can be done for self recovery if your vehicle is stuck. Say, you’ve gotten your ATV stuck and a single-line pull won’t cut it. If there is a suitable anchor point, such as a sturdy tree, you can use a tree trunk protector around the trunk, and then use a shackle to connect it and the snatch block. You’d then run the line back to a recovery point on the front of the ATV. You’ve now enabled your 2,500 lb. winch to pull 5,000 lbs. Keep in mind, the winch itself isn’t actually now a 5,000 lb. unit, but with the help of physics, you’re able to pull more weight. But remember—you’ve cut your rope length and line speed in half.

WARN Epic Recovery Kit

Having a proper recovery kit is essential in times like this, because without the proper equipment, you won’t be able to do a double-line pull. Warn offers a variety of kits for both powersports, truck, and utility applications.
