Adjustable climbing system

Here it is in extendo rocket mode.
the small gator biner was shifting a bit.
This dog snap solved that.

Any input is much appreciated.

2 concerns:

1- The dogsnap is part of your safety system. If that thing goes, you are in for a nasty drop of a few feet. Maybe you could install a quicklink?
2- The splice on the brown line. Is that HRC? If so, was it spliced like a traditional double braid rope?

Other than that, the system looks quite sound and clever.

Nick, 2 things. I don't see a brown line? Also, the dog snap and small prussic aren't part of the safety system. If they fail, all that could happen is the relative position of the friction hitch assembly could move up or down.

This is the same as Chris Cowell's system, as he has now switched away from use of a Ropeman.

I've done it with throw line cord for the extender prussic.

However, there's another method that is slickest and perhaps simplest of all, Rich's Anchor Bridge being the most gear intensive. It's makes use of an extendable harness bridge empoying a Ropeman on one end of a long rope bridge, with a backup knot a ways past the Ropeman large enough to not pass through the harness ring in the event of a Ropeman failure. It passed the PNW TCC gear inspection.

So, pending my choice of a new saddle (And I'm thinking the Sequoia SRT will work for me.) I'll be ordering a spliced on one end bridge from ya, sized for a Ropeman. 11 mm, I reckon. I'm liking that nice short stiff bridge ya made for my B'fly, but hey....

As well, I may soon be wanting another 600 feet of Blaze from Bishop, for ya to splice....or other line if I want to pay extra for a different but nominally or possibly better line.

Here's a pic I shot in Hawaii of Chris demonstrating his system [image]http://arbtalk.co.uk/forum/attachment.php?attachmentid=4487&stc=1&d=1212638417[/image]
 
From a safety standpoint, I like this last rendition much better. The girth hitch is a good idea. That oughtta keep 'er in place.

Is the bottom pulley needed? Would the system work the same without it?

Bring it on Rog! Let me know when you're ready.

The latest pic is the third rendition arbor101 has shown. This is from his first post:

I added the pulley so I can extend or retract the system with my weight on it. It actually works fine just through a biner but Im OCD so I just cant leave well enough alone. I did however like the way the pulley seemed to put less stress on the spliced eye on my climbing line when the system is retracted all the way.
 
Couldn't get the pic to embed from Arbtalk, so had to go to my picture to get it. Meanwhile, back ata Arbtalk, they're saying that the Ropeman could shred the bridge in the event of a fall.....but, again, a prussic might be better anyhow....

The ropeman just moves a little faster than a prussic. Thats probably only better for competitions. I think the system takes to long to setup personally. I use a modified Anchor Bridge during the work day that can be removed and stowed if it gets in the way (never does) or reinstalled in seconds for a long ascent.
 
I've heard rumbleings that the ropeman causes rope damage, I'm guessing to the core, because of the tight pinch that a smaller Biner causes between the ropeman and the ascender that attacks the ropeman

Def. A gear intensive system but very efficent. Great idea with the pulley to bring the ropeman back and forth under tension

My guess would be damage to the cover from the cams biting into the cover, not the core. Just a guess, though.

the cam isnt toothed nick, and hasnt shown any signs of wear on the cover, but there is a bad bend in the rope where the ropeman and binet connect, much worse when the users weight is applied, if you look at the pic, you can kinda see it,

I switched to an online prusik and haven't had a problem, I've also used a microscender, which worked great, but a little cluttery and bulky
 
Yep, I gotcha. Ironically, the "toothed" Ropeman (aka Ropeman 2)...

PIC00241.JPG

(picture shared from Storrick's website)

...has a steel, toothed cam as opposed to the Ropeman 1 with an aluminum cam. The toothed cam is designed to spread the load over a greater area, thus REDUCING rope damage in a shock load scenario. You can read about it a little on Wild Country's website here. It used to more bluntly say something like, "toothed ascender is gentler on ropes in a shock load."

Just thought it'd be worth sharing.

By doing so you have an endless loop of rope and you don't have to move to adjust the distance of your climbing hitch. I have found the only problem with this system to be unclipping to move your rope over another limb.
 
I agree with you Tyler, recrotching or doing anything like that is a huge pain in the butt with this system which is why i find it not worth it.

Agreed about the time consuming task of recrotching, but it is fun to play with.

I stick with my original anchor bridge, but I have seen the likes of which Kentucky Homeboy was talking about, with a single extendo-bridge.


Very interesting,
