How to get it up! ::013::

Everyone should have it aboard. Very slick. Chances are if you hang a hammock/tarp you already use the knots required.


Looks like it's time for me to pay another visit the rock & river rat shop.

Smart idea. I'm confused about one thing though. Everybody recommends the non-stretchy cord, wouldn't it be better to use the stretchy cord when doing this? If you're a single person trying to move the bike, wouldn't it be better to rig it up, build up tension in the rope, thereby effectively removing weight from the bike, then go back to the bike, move it forward (now possible due to reduced weight), go back to the rope, rebuild tension, so on and so forth? Or does the rope that is being used have enough stretch for this?

I've never done it so can't say. I'll let you know as soon as I get around to testing it by skidding a log or some such (the neighbors will no doubt think I'm losing it again). I'm thinking more about setting the bike upright or extracting it from a "oops, I didn't think it would sink that deep" mudbog rather than recovering it from over a bank...I hope.

What a great idea. I'm going to make myself a kit and carry it on the KTM until I get my S10.

I bought one of these - have yet to try it... I figure I should figure out how to use it before I get in a situation where I really need it (hopefully never). I admit, I'm dubious that I'd be able to pull the Super Tenere out of a ditch, on my own, using just this. But that's what it's for... I may be slightly better than nothing!

I'll be adding some 1" webbing to the "recovery kit" as well.

Somewhere in the recesses of my memory, I recalled your post Trevor. But I too am skeptical that your device is sturdy enough to move our big pig. And that's when I went looking for another option. Rescue squads trust z-drag systems to save lives. I'm betting it will work just fine for our bikes. As soon as the weather turns hospitable, my next ride will be to the climber's shop (an hour away here in BFE) to get outfitted and I'll try it out.



Might be something fun to play with after a few beers at the Romney Cycle weekend this spring. ;D

Yeah the main thing going for it is it's compact size. The pulleys themselves look pretty strong (one-piece forged aluminum) but the "rope" I'm not sure about. With a maximum load of 500lbs, it won't lift the S10, but should be able to drag it. Doing it on your own WILL make a mess of the bike, but I figure in a desperate situation where no help is likely to arrive any time soon... you gotta do what you gotta do...

Yeah - some of the rallys I went to in Oz they would do a tug-o-war. We could have the tug-o-tenere...

Not such a silly idea y'know - but without the tenere. Would be good to try some of these recovery solutions on a Romney-Cycles-supplied object (may end up being a log... we could outfit it with the Tuning Forks logo) so that we know what works and how to use it.

8) Oh yeah, this is gonna be fun.

Dynamic vs Static

You want static rope. Dynamic (stretchy) cord, well, stretches. This means that for every one foot of pull through the system shown you would expect the object to move 6 inches (2:1) You will get a fair amount less than this with dynamic rope which means you will be pulling longer and more for a given distance.

Remember that with this 2:1 Z-rig system you are multiplying your force. If you exert 100 pounds of pull you are exerting 200 pounds of force to the object you are pulling. Twice the force, half the distance.

The pre fab systems are all slick but absolutely not necessary. The pulleys are nice as they reduce effective friction but not necessary. If you can tie a loop in a rope you can make this work. Figure eight on a bight, alpine loop, etc.

As for the rope, you could just go get yourself some basic flat tubular webbing from any climbing supply house (REI, etc.) Here's a link;

http://www.rei.com/product/783605/1-military-spec-tubular-webbing

You can carry a whole bunch of this in less space than rope and it has a 4000 pound strength rating to boot. When needed, cut enough to tie off an anchor to your immovable object and to your bike. Use the rest to rig your Z-rig. Pull, reset, pull, reset.

I would suspect most of us, I do, carry a tow strap. This is the same stuff usable for this. The uses for tubular webbing are endless! Just have a sharp knife and a lighter to melt the cut ends and you're off.

Hey, I'm a Fire Captain in the fire service. This 2:1 Z-rig is the bread and butter to all haul systems we use. Simple, effective, and works.

I was hoping someone that had actually used such a rig would chime in. The webbing looks to be the bees knees. Do you still use the prusik brakes when set up without the pullies (I'm seeing a Trucker's Hitch)?

here's how to set up the webbing for 4-1 mechanical advantage using 4 carabiners

and here's how to use the ez-pull that I have..

An additional thought as you go to get yourself set up for a haul system....

If the Z-rig is not to your liking for whatever reason or you just don't have a good haul field, etc. , go get the loop webbing I referenced earlier and get your self some ratchets from a couple ratchet straps. Now you can use this as your hauling mechanism. Load the ratchet, fill up the spool, reset, fill up the spool, and so on.......

Just another way to McGuyver your way out of whatever you've gotten yourself in to.

Also, always remember that when using a mechanical advantage haul system you are exerting a lot of force to your bike, if that is what you are hauling. Don't just hook up and haul. Make sure you are not getting caught up on something that you are now pulling against with mechanical advantage. Force multiplying has been known to break things off of the item being hauled. This makes it equally important to make sure your anchor side and haul side are up to the task. Don't hook up to your handlebar ends as you will rip them right off!!!! Good "bomb proof" hard points.
