One.

One foot, if the line wasn't doubled back to the vehicle. If it was, they'd
need two feet of line to move the load one foot. Similar to a reduction gear
with a 2:1 ratio.

Re: Superwinch = junk
 

If they had a second snatch block on the recovered vehicle with the line
going back to the tree, then they would have a 2:1 ratio.

Think block and tackle....

The more pulleys, the more reduction and more you can lift easily, but
you have to have the pulley as an other end of the circuit, not just an
angle changer.

Re: Superwinch = junk
 

Huh???

The first snatch block is just an angle changer, you can have twenty of
them, but if the end of the cable doesn't hook back on itself, the 20
blocks will still be 1:1.

Re: Superwinch = junk
 

it's a 2:1 ratio, since the cable is hooked back on the driving force
(truck) the snatch block is not a simple re-vector of the force, since it is
going back to the truck. If the cable went though the block, then to another
tree it would be acting as a force vectoring point. Then, and only then
would it be a 1:1 ratio.

Re: Superwinch = junk
 

Just remember you're using twice the force to pull out the tree.
