    Default Rope Rescue

    Was wondering what most people are using for a 2 line rope rescue system for a lowering then hauling. We currently use a tandem prusik belay and a figure 8 or brake bar main line. Looking for the best way to convert a main line (brake bar or eight) to a MA haul system quickly, practical, and effective. Would like to see a diagram if someone know a good website. Thanks.

    Converting is relativly straight forward. Lock of the mainline and put some extra long tandem prusiks in front of the descender. Unlock the descender and tansfer the load onto the extra long prusiks. Insert your pulley system and off you go.

    Tandem pruisk belay works great...no worries there.

    There has been thread after thread about using an eight plate in your lowering system or in today's rope rescue systems for that matter. No sense in rehashing all that here.

    dfacer1,
    Send me an email, and I'll try to provide some insight. Basically we use a strap just a bit longer than our brake rack. (we've pre-tied this w/ 1" webbing, measured beside our brake racks) The strap is connected to an anchor, and the other end has a prussik and a single PM pulley. This prussik will be the ratchet prussik when the MA is built. However, its put in place and minded during the lowering. When lowering is complete, we set the prussik, and make the changeover to a haul system. The real benefit is converting back to a lower if needed, the rack can be re-established BEHIND the pulley and prussik, and the remainder of the MA is used to unweight the ratchet. Sounds a bit confusing, but I'll send a diagram, and maybe clear it up a bit. I've played around with LRHs, and think they do have their place. However the technique we use does not require the system to be rebuilt, as the case w/ LRH. Also, mini-haul systems (AZTEKs) work pretty good also, but I feel pretty confortable and confident in the way we do our changovers.

    Thumbs up Lowering system change over to Haul system.

    Hey pal,
    a good way to ensure a swift change over from a Lowering system to a Haul system is to leave that Brake Bar Rack or Figure 8 on the Chiefs desk as a paper weight and exchange them for a Petzl ID 20 (Red - G Rated - not the Gold or Blue ID).

    http://en.petzl.com/petzl/ProFamille?Famille=29

    Rig the ID-20 in the position you would nomally have the Brake Bar Rack / F8.

    When you need to change over to haul system, lock the ID-20 off (turn handle fully clockwise) - 1 Second.....

    Take a Rope grab (Prusik, Rescuecender, Gibbs) whichever one takes your preferance....I personally like the Prusik.
    From the Prusik rig your pulley of choice (36 kN).
    The Prusik, Carabiner and Pulley should be clipped to a Team members harnes ready for the change over - 10 Seconds.....

    Take the line that comes out of the ID-20 (on the right hand side) and rig this line through the Pulley you have established on the Prusik - 5 Seconds.....

    You now have your 3:1 rigged - Rigged in around 20 seconds...being generous.

    All this done in a few seconds without a Load Release Strap or Hokie Hitch in site.
    Certainly takes more time to change over systems the old school way.

    Now of course the ID-20 is good for those Urban Tech Rescue teams and those that don't get too dirty on the Cliffs but if you work in a ****ty environment like a Cave where you are up to your nuts in Mud the ID-20 won't like it, in this case take the ID-20 and swap it for the Brake Bar Rack you left on the Chiefs desk as a paper weight....now he has an even fancier looking Red paper weight with a cool handle thingamy bob.........

    What do you mean swap it? I think that the Chief should be called on the radio to bring the rack/8 or whatever to the incident scene so that you can effect the rescue.

    Isn't that what the Chief does? Make sure you have what you need to get the job done!

    Instead of putting your belay device on a normal figure-eight, tie a double figure-eight where one loop is about a hands-width longer than the other.

    Put your belay device on the shorter loop.

    You can clip your prussik/rescuecender + pulley onto the longer loop, leaving it at the ready. If you put it on someone's harness and they are not around when needed, you need to go looking (granted this should ideally not occur).

    The longer 8 loop will ensure that the prussik/rescuecender is going to sit nicely in front of your belay device. That allows you to quickly transfer weight and release the belay device.

    One final suggestion that will depend on your working environment. In this (and many of the systems described), you have no way to take load off of the haul system if something goes wrong. A simple and effective solution for this is that the rope to which you secure your belay/haul device then itself passes through a tied off belay device which is anchored. That way, you always have a few meters of rope through the rear device that you can use to release tension.

    As for which device, my personal preference is a rescuecender over a prussik since it requires fewer actions to set. Both work just as well.

    Hope that helps.

    Regards,

    Steve
