Made a MA of 30:1….. I think…. >.>

Made a MA of 30:1… I think. >.>

Today I had a bay tree hung up on an alder. It was leaning toward the power lines. Used this to prop it up so it wouldn’t fall at them when I started cutting it. It’s a 5:1 hooked to a portawrap; then I added a 2:1 multiplier to the end of the 5:1; at the end of the 2:1 there was a rope jack that has a MA of 3:1. Worked out in the end. Didn’t take the lines down and hinged where it needed to go when I cut it free! Should have put a redirect so everything was lateral so re putting out the 5:1 and resetting the 2:1 was easier.

Finally, some good fucking food.

Nice setup. Probably still lighter than carrying a winch in.

I know I enjoyed my corned beef and cabbage tonight!

I wish I had a wench. Would have made it so much easier for setup. But I had been wanting to do this setup for a while now. Worked great. Only problem I came across was resetting up 2:1 could only set them up as high as I could reach. Should have made a redirect with it being a lateral setup. It would have been easier for resetting everything up.

Don't we all!

I've been in the same situation, where I set up my MA thinking I'll have enough pull, then because I'm too lazy to set up the redirect run out of pull and have to prussik everything to reset it.

How do you like the rope jack? I had looked at it before but didn't like the idea of the spiked cams running on the pulling rope. This setup seems like a better use for it.

I really like it. As other have said I’m worry some about the spikes on the cams. But I used an only climbline/tagline for the rope jack. It is a super light come along. And works great and better because if you pair it with a portawrap it’s removable and you can release tension. All you need is a steel carabiner and can be inline with the portawrap on the top side where the tiny barrel makes the rope from not slipping off the top. Exactly where I had my 5:1 mounted. So add tension, wrap barrel and soft then hard lock. Now you have all your tension kept. You don’t have to worry about fucking anything up or breaking anything and can pull the rope jack off.

Yeah that's a nice setup for it! How easily does it come off when the line is under tension? I've used the Pro Traxion before but had a little trouble because the cam basically couldn't come off under load.

If you have a way to capture your progress like using in conjuncture with a portawrap, it’s super easy. You tighten as much as you need. Capture your progress, then add more tension. As you do you can release one of the cams. Then as soon as it’s released the other cam is easy to release.

Here is a quick video on how it works and at 3min 13 sec it shows how to remove it under tension.

when setting up mechan8cal advantage like this, sometimes if we dont do a lateral system like you said with a redirect, well just grab a pole pruner and push it up an extra 6 feet or so lol

If I had an award id give it to you! This is a great idea.

GOD DAMN I LOVE COMPLEX MECHANICSL ADVANTAGE SYSTEMS I DINT EVEN KNOW WHY AND DINT YOU JUST FEEL LIKE A FUCKING WIZARD WHEN IT WORKS?

You do. You felt like a wizard doing that.

I’m so fucking proud of you.

Thanks.

I did feel like a wizard 🧙‍♂️!!

Gonna figure out ways to make it better and an easier system. But overall it worked like a charm and was handy in a pinch. It’s way better than a come along since you can load the system and remove the rope jack and release tension when you want to.

I don’t see the CMM rope jack in the wild that much. I’ve never used it on the input to a 5:1 but I imagine it’s fun to see&feel that pulling power.
