German Friction Saver

Hey, Mark I have a JPEG picture of the new German Friction Saver on my hard drive. How do I post it here so everyone can get a look at it?
 
I've just posted a picture of it on another topic, but since this is a more specific thread, I'll repeat it here:

Personally, I love using a long adjustable friction saver, but can't see the advantage of the LJ part over a friction hitch.

With the camming unit there will be a known amount of shock absorbing if the climber takes a fall. Rather than all of the load being absorbed by the rope and some spring in the tree the cam, and some hitches, will slip/grab.

Think of the cam as a reusable Screamer:

I should have mine in a few weeks. When I've had time to use it, I'll give a report.

I would think a person would only have to buy the lockjack part of the system as the other hardware is readily available.
Tom where are you going to buy this?
I would like to buy it.
Is it available to me (the public?)

I NEVER had any significant fall while on a tree (more likely to happen stepping down from my van), the advantage Tom mentions still doesn't convince me. But it's true we better try it before saying anything else.

Tom, I don't see that any mechanical device is an advantage over a prusik type fricton hitch in shock loading situations. The only advantage to the LJ is its resistance to sliding when rubbing the tree. This actual device can be used chokered, which is its advantage - In the picture, imagine threading the rope through the small shackle before the pulley. It just hangs there until the end of the rope is pulled back through the pulley and then jams in the shackle to bring all to the ground.

I used pulleys in friction savers a long time ago - I don't like the lack of friction, it can be self defeating sometimes.

The bend radius is nothing to worry about, especially in work positioning with very high safety factors.

I thought about that. But does it mean that the splice has to be calibrated so that it goes through the pulley and jams in the shackle? I don't think my XTC splice would go through the pulley. Maybe one should mirror the picture and then use something on the non-spliced end of the rope that has just the right size to make it work...???

I agree...

I just can't see how you can justify spending that kind of money for a friction saver. The bennifits doesn't outweigh the cost. It looks pretty and its a Strasser design so everybody wants it?

I think that this equipment is not for everyone. Climbing off this new false crotch is quite amazing, you can extend the travel distance of a swing by 25% and to pull up over a branch seems effortless. So if you climb only conifers then their might not be of great benefit for you, but if you need to move latterly in the tree nothing compares. I did not at first think there would be a big advantage but the first time you run 40 feet (not walk) out a branch you will know. Some guys fish with a 19$ combo others spend a 1000$ on just a rod, they both do the same job and unless you are a great fisherman you will never know the difference. If I can reduce the friction on my system by 4% that is huge and I notice right away. So if this saves me 10 minutes a day then it pays for it’s self in what two weeks? I have climbed in a similar system for 8-9 months and would never go back!

The point is:
Less friction on the friction saver means more friction on the friction hitch.
Then again, the advantage will depend on what hitch one uses with what type of cord and all that stuff. They are all inter-connected issues...

OK, guys... I feel the point in time has come to ease off on this topic a little! World Wide Web, instant, globe-spanning communication... the problem being to actually find the releveant info's! In the case in question, check out Hubert's statement (it's right here in climber's talk, ART4Trees) concerning the rope-guide, he brings us these gizmos, so HE should know. It'd be better to clear up one or two points and to avoid further speculation running wild, so for tech-talk he's really the guy to quizz. Hubert has provided a number of climbers with rope-guides, I've been climbibg mine for a couple of weeks. My feeling is, obviously there are up & down sides to every new piece of equipment, but this device runs very smooth, it's compact & well thought out. A lot of time has gone into it's production- in other words, it's the works! Unlike the Lock-Jack, the most exciting thing about it is the modular fashion in which it can be used, not only as a friction saver. You'll have tocheck that out @ TCI! Now what your subjective opinion is on the topic is, is one matter, objectively seen Hubert is someone who's been very innovative over a long period of time and I'm happy to offer any support I can. At the end of the day , it boils down to the argument of price. Everybody wants cool, innovative products, but they'd better be cheap... buy two get one for free kind of thing! My feeling is, you're not just buying a product, you're also encouraging development & innovation of new devices & techniques.. let's face it, if these guys don't have our support, wher's the incentive to carry on? To end this on a positive note... ITCC/ Seattle was great! We rocked, a big Hi! to all who were there!... Mark.
 
hey Greenman I use a friction saver with a large aluminum ring on one side and a small pulley on the other is there that much of a difference ,other tha getting it to the ground?
