Holmentree, can you give me some more info on the diagram you sent me? (Thank you very much. This is really helpful.) The knots used at the top is a prusik knot? Bottom one not shown. I want to put something like this together. I have a small hand winch that pulls one ton, but it can pull only 2meters of cable length.

This helps explains mechanical advantage and lift.


 
John, I own this 5 to 1 setup and I only used it once.
Petzl pulley blocks and a few carabiner and 2 prussics set me back close to $400.

The top hitch is called a Valdotain Tresse Knot (VT)
Bottom one is a 2 wrap Prusik Knot.
I never used it again because of the work of setting it up and sorting out the rope.

This is what I use the most, I can feed any length of rope through it. And only about  $40.

400 bucks is a lot of cash. In fact, I own a pulley very similar to to the one from maasdam. Only difference is that it has cable on it. It fits snug onto my back-rack. Only problem is that the cable length is only 3 meters, and it pulls only one ton. I double up the pull power with a snatch block similar to the diagram that DMcCoy posted.

That's a great picture John. Nice setup you have there....are those wet sock shoes chainsaw compliant? ;D Just kidding.

Get rid of that Maasdam cable puller and get the Maasdam rope puller like I showed earlier. You won't be sorry.

Especially since he's already carrying a rope anyway. With the rope puller, your pull distance is only limited by the length of your rope.

The rope puller seems to be a better bet than the cable one. you can pull as far as the rope goes. I get stuck with the cable since it is sold in short lengths only, as well as it weighs a lot more than rope, making it miserable to carry up and down those slopes!
Holmentree, as far as the shoes go, they are traditional Japanese forester boots. These days they are steel tipped and spiked as well. They were invented by the Japanese ages ago for effective footing in mountainous areas. I use standard western style boots as well. I have a set of waterproof chainsaw boots (that comes up to the knee) for when working in muddy areas.

The boots look something like this. I know it looks kinda ninja :D, but they work well! It takes a bit getting used to the split-toe feeling, but your feet don't slide around in the boot when working on heavy slopes.
