So what you're saying is that the "for every action, there is an equal and opposite reaction" doesn't apply here? Granted it moved, but it appeared to only move a few inches which is the slack coming out and the stretching of the wire rope. Physics 101 would lead me to believe if you're pulling at the front and anchored at the back of the vehicle, no matter how many snatch blocks you use, you're still applying equal and opposite force to the front and back of the vehicle.

@rioaguanegra I will try to give a simple explanation. What happens when you draw in the winch line? It gets shorter. You have a fixed point snatch blocks in front, beside, and behind tied to trees that won't move. You have a 4th snatch block on the bumper. The line goes all the way around the 4x4 to the tree behind to the bumper and back to the rear tree. When you draw in the line, the only place that can get shorter is the distance between the 4x4 and the rear tree and that pulls it backward

Hey.... correct me if I'm wrong, but why doesn't the truck just drive out of there? Is the driver incapacitated? I don't quite get why these people are standing around listening to Professor Snape. Has he threatened them with the patronis charm? Pardon me if I'm stupid, but my truck has reverse. Wouldn't that work in this situation? Or is this area populated with hippogriffs?

@TheBlammoman This is a demonstration of a complex winch setup. Its a little easier to show the setup without brush, mud, etc in the way. Also, its better to learn to use the equipment before you need it. If you would watch instead of criticize, you may learn something.

@tj4liter View the "Reverse Winch Pull" video from "4x4Training". They demonstrate this a little better than I did. If you understand how block & tackles work and you draw it out on paper and think about it - it should make sense. All of the pulleys are in fixed locations and will not move except the one on the truck. When you reel in the rope, it gets shorter. The only pulley that can move is on the one on the back of the truck and the distance between it and the tree has to get shorter.

Very nice man! Im a retired firemen and we did something like this years ago just to secure the vehicle over the side. That enabled us to use cutting tool to take the doors off and get the victim. She lived. It was kind of my hobby, not sure what the other shifts would have done..

@TheBlammoman your so right!

[marcusacmedina]

the secret of this kind of recovery technic is to move only the closest snatch, and in this case it is the the car snatch block with are in the back of vehicle... greetings from Brazil

Nice use of pulleys .

[cwmedic]

There is force pulling the vehicle forward and backward at the same time. However, there is a 2:1 mechanical advantage in the rear... there is twice as much force being pulled on the rear because you are moving 2 times more length of rope than you are moving distance of the vehicle. This double force in the rear overcomes the force in the front and allows the only movable pulley to travel.

Simplest explanation would be, since the back use snatch block, it double the power of the winch 'backwards'. Once you start winching, the back will have more pull than the front. And once the truck start moving backwards, more rope can be pulled into the winch.

The key here is the cable goes from the back tree through a snatch block at the rear of the truck the finally anchors back at the back tree.

This double cable between the back tree and the back trucks snatch block must shorten.

Hope that helps.

@rioaguanegra

Yes you're right if he had only gone from the truck front to front tree then the other trees then finally ending at the truck, but he didn't.

He went from the back tree snatch block, through a snatch block at the back of the truck then finally anchors back at the rear tree. So now the double cable from the rear of the truck to the rear tree must shorten.

Hope that helps.

That is very ingenious and I will remember that if I ever need...

Thanks!
