Thanks Sharon that link will come in handy! Now all I need are a couple good links for a caver's Tyrolean Traverse, as we have a ravine we'd like to rig

I haven't seen a link for a Tyrolean, but there probably is one floating around somewhere on the internet. ;D Huntsville Cave Rescue Unit is holding their annual Tyrolean Traverse at Desoto Falls on July 15. The HCRU folks probably have some tips on rigging up a traverse.

If it's a sloping traverse (but not too steeply sloping), just rig it like a zip line. Nothing too complicated there, but remember the load on each anchor could be quite high. You also need to figure out where a person is going to "stop" - either out in space, or when they connect with a rock or tree! I suggest using a tandem pulley carriage initially (rather than a regular single pulley) because it will make the traverse not quite so fast and scary (or dangerous). Best quick advice - find someone who knows about rigging them, and persuade them to help you the first time or two. :-)

Thanks Sharon and NZcaver. We may have to go to the Tyrolean Traverse to talk with HCRU folks so we can learn. Another caver who lives in our neignborhood took a quick look at the ravine last week before he had to zip off the NCRC. From the twinkle I saw in his eyes I don't think it would be hard to get him to help us rig it. ;D

Not only can he/she help rig the tyrolean but can also be the "guinea pig" first person down the rope to test it out! According to what I have read the loads on the ends of the rope are really high when doing tyroleans and one must be careful not to overload them. Our usual rope is good for about 5000 lbs static load so even if the load is 500 lbs the ends could hold ten times the load. Still it is better not to stress rope to the maximum if one can help it. I'll get out my copy of "On Rope" and see what it says... Thanks NZ,

Oh, she's been caving since she was very young! Hey good deal that you, Allen and Scott did all the rigging on the Mock rescue. Want to help rig a ravine? Do you mind telling us more about this years NCRC?

It was great. It was held in Somerville,Ala. at Union Hill school. It is in the heart of some awesome cave systems. We were there for nine days . That meant camping for nine days with no electricity in camp Man I missed my fan at night. ;D They had showers in the gym of the school where the seminar was being held. We ate breakfast & dinner in the school caf. Lunch was ate on in the field. Every level did things different. I was in level 2 so we had class starting at 8am until about 11am then head out to the caves or cliffs to practice what we learned that morning in class. We would get back about 6pm & eat dinner. Then it was back into class until 10pm. Some nights we got out at about 8:30pm so we could do (check-offs) on the skills we were learning for that level. Some of the skills we learned were how to build compound hauling systems, single rope pt pickoffs ( climb the same rope your pt is on & lower him to the bottom while you stay up on the rope where ever they got stuck), counter balance systems & much more.......... All in all I learned a TON of stuff this year. On next to the last day we had a BIG mock rescue that involved all three levels working together. This the only time all three levels were together in the whole class time. The last day we had a debriefing on how the mock went & then we all headed home .

But we were spoilt the year before in Indiana, where we had an outstanding catering staff. Not that NCRC is all about food, but it does make a difference to morale... ;D
