So you can use a single snatchblock to either change the angle of the pull OR double your pulling power, you don't need 2 snatchblocks for that.Are they for real !?!? 1 line in and one out is 1 : 1 ratio You can EITHER GO BACK TO YOUR GRADE 7 PHYSICS NOTES or google it bud. So you can use a single snatchblock to either change the angle of the pull OR double your pulling power, you don't need 2 snatchblocks for that. Note that when you double the power, you also cut the line speed in half." This double-line setup with the snatch block doubles the pulling power of your winch. This anchor point takes some of the strain off your vehicle, which is important when you are recovering a heavier rig. The winch cable goes through the snatch block and back to an anchor point that’s next to your vehicle. If you are moving another vehicle, the stuck vehicle is attached to the snatch block. The snatch block is attached to an anchor point and positioned directly in front of the vehicle. In a self-recovery situation, you’d run the cable through the snatch block and then back to your own vehicle. The second is if you want to recover a vehicle that’s bigger than yours.Ī double-line pull involves using the snatch block to redirect the winch cable back towards the winch. The first is if you think your winch doesn’t have enough muscle to pull out your vehicle. There are two common situations in which the double-line pull is useful. When you see a crane with a whole whack of lines going through multiple sheaves count the number of lines you see going between top and bottom blocks and that will tell you the Mechanical Advantage of that cranes lineĪnother type of winch rigging that uses a snatch block is the double-line pull. Twice the amount of line is required for the hoist/pull and that is what eliminates the need for larger load capable line. To accomplish 2:1 MA you would need a single block attached to the load (Jeep) and a second block attached to.well.a tree or other similar anchor. A single sheave (wheel) block is more commonly referred to as a TURNING block used to allow pulls from different angles and is a 1:1 MA. NO - You don't have a 2:1 (double capacity) Mechanical Advantage with a single snatch block. NO - Don't ever use a frayed cable because sure as sh.t someone or something will get whacked really hard when it does (and it will) let go! NO - The only dumb question is the one that was never asked. Running with a smittybilt xrc8 (8000 pounds) and thinking of adding synthetic line since my cable is fryed.NO - NO and NO So wouldn't I need to have double the capacity strength in my rope or cable? I would think so however never heard that plus I think I would have found out recently with die consequences. Might be dumb question but while using a snatch block to make a double line pull, it doubles your pull capacity of your winch right.
