As mentioned above, it can be used for a wide variety of activities. They were designed specifically for the application of the VT prusik knot and its intended purposes. Uses of Prusik Knots. The VT Prusik is easier (once you learn the proper knot) to tie than two Prusik’s and when used on the belay rope during a lowering operation, is easier to mind. This just allows me to drop the JS for popup maker on all pages, for use with the generic “popup” shortcode. Unforunately when Bluewater Ropes and Rich Carlson created the VT Prusik (gear), they decided to name it after a knot which can create a little bit of confusion. Using your standard rappel device, rappel down to the knot, attach the VT, clip onto the VT, unclip your rappel device, slide the VT down to the knot, get back on rappel and be on your way. The VT knot is a prusik that moves easily when needed, but locks up when you taken your hand off of it. Personally, I like the official ones. Rich Carlson partnered with BlueWater Ropes to make the VT Prusik. Press J to jump to the feed. You don't need to have one "official" VT Prusik, you can make your own out of accessory cord or use a sling. If you choose to make your own using traditional materials be cautious of using them in dry conditions or for long periods of use as they could wear rapidly and have compromised integrity. That is the main feature of using a VT prusik knot. You can isolate the damange in the rope by tying an alpine butterfly with the damaged part of the rope in the loop of the butterfly. I'll be happy to answer any questions too! Also, I am wondering about ascending/descending a tensioned rope...if I encountered this scenario, my thought would be to use two standard Prusiks, alternately weighting and unweighting them exactly as I would do to ascend or descend an unweighted rope. Your email address will not be published. Acsending - There are better devices and techniques, but a VT can be used to ascend in a pinch. The VT is a piece of technora designed specifically for tying the VT knot. The purpose was to critically examine the capabilities and limitations of the VT Prusik as a device suitable for managing fall arrest on a rope rescue system while lowering or raising a 200kg mass. Just to clarify the VT can be moved easily enough by hand under tension? One of the advantages is that, unlike prusik cord, under high load the sheath of the VT Prusik does not melt, so only one cord is needed. Our SAR technical rope rescue team use the VT all time or passing knots on rappel. They're cheap and durable and I like the feel they give when in use. Depending on the intended use of the prusik, this might cause the canyoneer to prefer one over the other. You don't need to have one "official" VT Prusik, you can make your own out of accessory cord or use a sling. Is that right? Correct. BCCTR BCDTM) demonstrated favorable results that were within industry acceptable performance criteria for: The human operated tests we conducted produced results that compared favorably to other tests we have either witnessed or been made aware of utilizing Nylon TPB (with human operators). The primary purpose of the prusik knot is for use in emergency situations. For the situation of ascending a rope, the XT might be better. Looking for a volunteer to handle next week's topical post. Basically an introduction, trip report, and beta all rolled into one. Do you know if there is an advantage to using the VT Prusik over standard Prusiks in this scenario? I'm sure I'll think of more uses for the knot and device, but it is a very useful thing to have in the canyon. Your email address will not be published. On a VT they are woven. This video is a nice demonstration of how to tie the knot (note, he's using a Bluewater VT). I could maybe make a video.). We’re switching from using dual Prusik’s as a Progress Capture mechanism to a single VT Prusik on both our main and belay ropes. What sets it apart from traditional Prusiks is its super tough, heat resistant Technora sheath over durable nylon core strands, along with its unique open-end design. It is a favored emergency knot for these activities because it is quick and relatively simple to make. In 2013, Rigging for Rescue began examining the Bluewater VT Prusik (configured as a Schwabisch ‘Max over One’ hitch) as an alternative to the Tandem Prusik Belay. Mechanical devices with purpose-built fail-safe mechanisms will undoubtedly prove more reliable for fall arrest versus a user-configured system such as Tandem Prusiks or the VT Prusik. Teams operating in remote environments with longer ingress/egress distances often favor lighter weight, multi-purpose systems and devices as part of their overall mission profile. Changing the coordinate system Avenza Maps displays. The very first thing you need to know is that the VT Prusik is both a knot and a piece of gear. The laboratory style tests (i.e. Since the 2014 ITRS presentation, three primary areas of inquiry include: Additionally, tests were conducted with the tensile testing machine on drop test sample ropes and Prusiks.
