An English Reeve system coordinates the control lines for up and down movement. The Prusiks serve as a backup, should any of the control lines fail. There is a lot more to tensioned highlines than two ropes between two points. There are several different ways to construct these systems. Highlines can be categorized into two categories, the first being horizontal highlines. These highlines are for the most part level and, like all highlines, go from point A to point B. The second category is angled highlines. These highlines span from point A to point B on an angle. An example could be a highline spanning from the top of a cliff to the bottom. There are variations of these highline systems, like slackline highlines and dual-track highlines. Tensioned Horizontal Highline System When dealing with highlines, there are several drawbacks you must be consciously aware of, the first being the stress put on the anchors and equipment. Anchor angles and the forces exerted on the anchors, is very important to keep the angles you create in your system between 45 and 60 degrees. Doing this will, for the most part, distribute the load force equally amongst the anchor points. In tensioned highline you can have a lack of an angle between the anchor points (highline connections). Knowing anchor forces, it’s easy to see and understand that these anchor points are going to see a lot of stress. #rig#rigging #rop#ropeaccess #rop#roperescue #tec#technicalrescue #hig#highanglerescue #lowangle #res#res#rescueing #riggingforrescue #rescue #rigging #slackline #rope #technicalrescue #rockclimbing #confinedspace #confinedspacerescue #highanglerescue #roperescue #rescue #roperescuetraining #pulley #pulleys #highlineconnections #tensionedhorizontalhighlinesystem

10 facts you didn’t know about knots: part 1 1. The word “knot” is related to knob, knoll, and knuckle, but not to knowledge. It is knoten in German, knot in Dutch, knut in Swedish, nudo in Spanish, and noeud in French. 2. The Inca’s only “written” language was a system of knots tied into necklace-like “documents” called quipus, or “talking knots.” Some scholars think quipus recorded only numbers, but others believe that they also told stories and encoded historical events. A select class of Incas apparently interpreted the knots, and the code has never been definitively deciphered. Knots were also used for record keeping in ancient China, and the Chinese Book of Changes, almost 2,500 years old, associates knots with contract and agreement. 3. The “bitter end” of a rope refers to its working end, intended to be tied off to a bitt, a cleat-like fastening point found on docks. If a longshoreman bobbled a thrown line or missed his tie-in move as a ship came in to dock, he might be left “hanging on to the bitter end” as the untethered ship drifted perilously past its mark. 4. The “feel” of a rope is called its hand. A hank is a looped bundle of rope, e.g., a lead line done up in a mountaineer’s coil. A bend is a knot that ties the ends of two ropes together. A hitch attaches a rope to a fixed object, such as a tree or carabiner. A short section of slack rope that does not cross itself is called a bight. If it crosses itself, it’s a loop. Twist a loop and you form an elbow. 5. A “climbing rope” is a misnomer. “Rope” properly refers to the raw material—a spool of accessory cord, for example. Once cut to length and given a designated purpose, a rope should be called a line. #rop#rope #rig#rigging #res#res#rescueing #con#confinedspaceue #rop#roperescue #ropeaccess #roperescue #ropeaccesstechnician #rescuerigging #riggingforrescue #rescue #rigging #slackline #rope #technicalrescue #rockclimbing #knot #confinedspace #knots #knotcraft https://www.climbing.com/news/10-things-you-didnt-know-about-knots/

The equalizing figure-8 knot is an excellent variation of the figure-8-on-a-bight knot which allows a climber to equalize two or three different anchors or pieces of gear with the climbing rope rather than with slings or a cordelette. Great Knot for Tying Into Anchors It’s particularly good for tying yourself and your rope into a belay anchor. By equalizing your anchors, such as at a belay stance, the knot distributes the weight load equally on all the anchors, which increases the strength of your anchor system since no single piece will be shock-loaded in the event of a fall. Knot Advantages and Disadvantages The advantage to using the equalizing figure-8 knot is that you don’t have to carry lots of extra slings or even a cordelette when you’re climbing a multi-pitch route. The knot’s main disadvantage is that the anchors it is clipped into the need to be close together rather than far apart. The farther apart the anchors, the bigger and longer the knot’s loops have to be to equalize the load. Ideal Knot for Bolted Anchors The equalizing figure-8 is an ideal knot to use if you’re climbing a long route with bolted anchors. When you get to a two-bolt belay anchor, you just have to tie the equalizing figure-8 knot and clip the loops or ears of rope into a carabiner on each bolt hanger and presto, you’re safe, tied in, and ready to put your partner on belay. Best Used When Swinging Leads It is best, however, to use this knot as your tie-in point at the anchor only if your partner and you are changing leads for each pitch. If you’re leading all the pitches, it is better to use a cordelette so you don’t have to untie the primary anchor knot before heading up the next pitch. #rop#rope #rig#rigging #res#res#rescueing #con#confinedspaceue #rop#roperescue #ropeaccess #roperescue #ropeaccesstechnician #rescuerigging #riggingforrescue #rescue #rigging #slackline #rope #technicalrescue #rockclimbing #knot #confinedspace #knots #knotcraft

{Werbung} Das geliebte Thema in jeder Feuerwehr sind Knoten. #sarcasm Da Knoten, Stiche und Bunde aber nach FwDV 1 zu den Grundtätigkeiten gehören, sollten sie genauso beherrscht werden, wie Schlauch ausrollen: Bei Null-Sicht und jedem Wetter. Dafür haben wir bei uns auf der Wache die @kts23_knotentrainingsstation. Hier kann jeder jeden Knoten in jeglicher erdenklichen Lage üben. Man kann z.B. testen, wie sich der Rettungsknoten anfühlt, wenn man in ihm hängt. Oder man baut die Sicherungskette in der Absturzsicherung auf und lernt wie ein Malbmastwurf richtig umschlagen muss. Super Sache, super Ding und schadet nicht, wenn man mal 5 Minuten Zeit hat und die Basics "mal eben kurz" übt. Auf dem Bild sieht man einen Flaschenzug, gebaut aus einem Kernmantelstatikseil, einer Bandschlinge und 4 Karabiner. Verwendete Knoten: Doppelter Achter mit Spierenstich als Festpunkt, 2 Butterfly-Knoten, Halbmastwurf mit Schleifknoten www.kts23.de (Patentiert) #kts #kno#knoten #training #ausbildung #knot #knots #knotcraft #rope #roperescue #ropeaccesstechnician #roperescuetraining #rigging #riggingforrescue #rescuerigging #technicalrescue #lowangle #figure8 #climbing #rockclimbing #Feuerwehr #Fir#Fireter #Fire #Retterherz #Retten #Rescue #sai#sail/a> #sail #trainyourprobie

Here are the four friction knots, their uses, and their advantages and disadvantages.🧗🏻‍♂️Prusik Knot🧗🏻‍♂️The Prusik knot is the most commonly used friction knot for ascending a rope. It’s easy to tie and very secure when it’s loaded. The disadvantages of the Prusik knot are that it is difficult to dress well and that it tightens up, making it difficult to release and slide up the rope.🧗🏻‍♂️Klemheist Knot🧗🏻‍♂️The Klemheist knot is a friction knot that is used for ascending a rope and for self-rescue when a climber needs to escape a belay. Like a Prusik knot, it slides easily on a rope. The advantages of a Klemheist knot over a Prusik knot is that it is easier to release its grip on the rope after being loaded, works in one direction, is faster to tie than a Prusik knot, is easily untied after being loaded, and can be tied with webbing.🧗🏻‍♂️Bachmann Knot🧗🏻‍♂️The Bachmann knot is a friction knot that utilizes a carabiner as a handle and is used to ascend a fixed rope. While the carabiner makes it easy to slide the knot up the rope, it’s smooth surface doesn’t grip the rope so accidents can happen. The Bachmann knot is ideal for rescue situations and as a safety back-up since it releases when it’s not loaded, but automatically grips the rope when it is loaded. 🧗🏻‍♂️Autoblock Knot🧗🏻‍♂️The autoblock knot, also called a French Prusik knot, is an easy-to-tie and versatile friction knot that is used as a safety back-up knot on a rappel rope. The knot is tied on the rope below the rappel device and then attached to the climber’s harness through a carabiner on a leg loop or the belay loop. The knot adds friction to the rappel and allows the climber to safely stop mid-rappel to rearrange the rope or do another task. The knot should never be used to ascend a rope since it slips rather than grips. Nor should it be used as a lowering device since the climber could lose control and burn through the nylon cord. #rop#rope #rig#rigging #res#res#rescueing #con#confinedspaceue #rop#roperescue #ropeaccess #roperescue #ropeaccesstechnician #rescuerigging #riggingforrescue #rescue #rigging #slackline #rope #technicalrescue #rockclimbing #knot #confinedspace #knots #knotcraft
