ROPE WORK
2 Terminology A.The end, or working end, is the part of the rope in which the knot is tied. The unused portion is called the standing part B.A bight is a simple reverse of direction of the rope, in which the two strands do not cross each other C.A loop is a reversal of direction in which the end crosses the standing part D.A turn is a loop that passes around an object, often another portion of the rope
3 Overhand Knot Simplest of knots Jams easily and is difficult to untie Useful as a “back up” knot to another knot to prevent the principle knot from becoming untied To Tie -Form a loop and pass the end through the loop.
4 Reef Knot For tying two thin ropes of equal size together For tying bandages because it –lies flat –will not slip –is easy to undo
5 Reef Knot Begin with an over and under crossing Bring the ends back above in a reverse crossing The completed knot is snugged up by pulling on the ends To undo a reef knot - grasp the standing part and the working end of one rope and pull the two parts apart
6 Other Knots Modified Reef Knot Clove Hitch Prussik Knot Munter Hitch Figure-Eight on a Bight Bowline Double Bowline
7 Care of ropes Store in an opaque, vented covering Stored on a shelf or hook to avoid dampness Do not: –drag through mud or dirt –step on –ski/snowboard over (edges will cut)
8 Dependent Belay System Belayer is tied into part of the system The belayer is tied off to a fixed object, and controls the rate of descend of the toboggan by means of a roped looped around their body “better feel” for what is going on at the other end of the rope May also be placing the belayer in potential danger
9 Dependent Belay System - Downhill
10 Independent Belay System Belayer is not part of the system Can tie off and go for help Belayer is less subject to potential danger
