Yup. You can also do an array of those in a V shape in soft ground. This is less sensitive to the dirction of pull as well.

You don't have to cut stakes, you can carry them. Think nesting tubes with an angle cut on one end. And steel will punch into the hard stuff where wood won't. Make these into a break down rack and you give up no space.

Read the page. That's a 4000lb holdfast.

self winching

I've been thinking about this very issue.

There is a company out there that puts out a kit called the PSSOR

BTW, I'm not endorsing this company, they just have the right idea on how to get out by yourself.


Considering the price of this setup, I've found some rock climbing pulleys that are really small



Say, three of these a few prusik knots and about 100' of non-stretch 1/2" cord should do the trick.

I say three because if it's just you, you'll need to be on your bike to balance the bike, while you are pulling on the cord, thus hauling your bike up the hill, out of the mud, etc.

Normally, as in the video, you would only need two. But, if you want to loop back towards the bike, you'll need a third pulley.

Check again, it's a 1-1-1 system for 1800-lb.
The 3-2-1 is 4000-lb.

here is a 5 to 1 set 8mm line (5/16)

they have a prussic lock set up to hold load

For what it's worth to the group, A friend and I both carry similar z-drag/pulley setups on our bikes as part of our toolkit (this is a toolkit thread right?) Anyhow, they've been useful many times for multiple purposes (as seen in the photo). I consider it essential kit when I go real far out where no cars ever come by.

How many (SWAG=99.8%) would ride up - "Oh noes - the trail is blocked and we have to turn around" - instead of clearing it for not just themselves but others that follow on?

Excellent! That's a 5 clapper!

just thinking, as long as one has a few pairs of pulleys and 2 prussiks, here is a way to increse a lot the mechanical advantage.

it is certainly trickier to operate since there is no automatic sliding of the prussiks. Pulling 1 of the loops segments sideways will provide quite a force to bring both pulleys together, thus pulling the load (on the right).

This doesn't take much rope either, loops could be 3-4 feet long only. I would call it a rope crank!

pulls a loop, green prussik pulls the load.
slide the yellow prussik closer to load, let go of the loop, yellow prussik holds it,
slide green prussik closer to load, repeat.
of course the diagram is not to scale, and the distance between both prussik is your max advance per 'crank', so put at least 1-2 feet between them.

Or get a petzl tiblock and save the need for a prussic or any type of friction hitch.

That would add expense and weight over a simple knot, but could make the process go faster and be easier for one person.

It weighs less and is smaller than a piece of cordage.

I like things that serve multiple purposes. I keep a few Nite-Ize Figure 9 carabiners in my kit for camping anyhow, so I have them when I'm most trips. They come in several different sizes, but all function the same. They could easily work in the setup suggested above. They are great for guy-lines on your tent too.
