Although a snatch block is a simple piece of equipment, it is quite handy. It drastically improves winch functionality. If you use a winch, you certainly want to have one in your gearbox. It will provide a host of options in a situation of self-recovery.
Basically, a snatch block is nothing more than a pulley block that has a side plate that you can swing open. It makes it possible to fit the cable over the pulley instead of threading the winch through the opening.
This simple piece of equipment allows you to change the direction of the winch cable for an offset anchor point. It also works to increase pulling power.
Offset Anchor Point
It is important to ensure that the cable spools evenly on the winch drum. Pulling at an angle may cause the cable to bunch up in the winch drum. When you do not have an anchor point right in front of the vehicle, you can set up an angled pull with a snatch block.
All you have to do is run the winch cable through the block to the offset anchor point. Next, find the second anchor point, which will be offset in the opposite direction. Attach to the second anchor using a choke chain and use the tension from the two points, positioning the block in from of your vehicle.
A double-line pull is another type of rigging with a snatch block. If you need more muscle or want to pull a larger vehicle, this pull is useful.
Use the block to double the cable back to the winch. For self-recovery, run the cable through the block and then back to the vehicle. Attach the block to your anchor point and position it in front of the vehicle.
For pulling a stuck vehicle, attach that vehicle to the block. Run the cable through the block and back to the anchor point near your vehicle. The pulling power of the winch will be doubled. This will reduce the stress on your vehicle, which is vital if pulling a larger vehicle.
With a little creative thinking, a simple snatch block becomes an amazing tool. Be sure to practice winch rigging before your next adventure.
