Trucker's Hitch
The trucker's hitch is a compound knot commonly used for securing loads on trucks or trailers. This general arrangement, using loops and turns in the rope itself to form a crude block and tackle, has long been used to tension lines and is known by multiple names. Knot author Geoffrey Budworth claims the knot can be traced back to the days when carters and hawkers used horse-drawn conveyances to move their wares from place to place. Variations The portion of the trucker's hitch which differs in the following variations is the method used to form the loop which the working end slides through to produce the mechanical advantage. The different methods of forming the loop affect the ease and speed of tying and releasing and the stability of the final product. The variations are presented in order of increasing stability. Sheepshank style loop This version of the knot uses a sheepshank-like construction, in this kind of application also known as a ''bell ringer's knot'', to for ...

Alpine Butterfly Loop
The butterfly loop, also known as lineman's loop, butterfly knot, alpine butterfly knot, Swiss loop and lineman's rider, is a knot used to form a fixed loop in the middle of a rope. Tied in the bight, it can be made in a rope without access to either of the ends; this is a distinct advantage when working with long climbing ropes. The butterfly loop is an excellent mid-line rigging knot; it handles multi-directional loading well and has a symmetrical shape that makes it easy to inspect. In a climbing context it is also useful for traverse lines, some anchors, shortening rope slings, and for isolating damaged sections of rope. History The earliest known presentation of the knot was in A.A. Burger's 1914 work ''Rope and Its Uses'', included in an agricultural extension bulletin from what is now Iowa State University. Burger called the knot a lineman's rider stating it was often used by "linemen and especially telephone men". The knot's security and ability to withstand tensi ...

Artillery Loop
The artillery loop is a knot with a loop on the bight for non-critical purposes. The artillery loop must have the loop loaded or it will slip and contract easily. It is an inferior knot to the alpine butterfly knot, possibly dangerously so, in that it can be yanked out of shape and turn into a running knot or noose. Budworth states that this knot is often described as being best suited to take a load on only one of the ends, but reliable information on which end is difficult to find. Tying the knot Image:ArtilleryLoop HowTo.jpg, Artillery loop step by step Image:ArtilleryLoop FinalKnot.jpg, Finished Artillery loop Usage The name ''harness loop'' derives from the fact that the knot was used when assisting horses on difficult terrain. Similarly, the name ''artillery loop'' or ''artilleryman's hitch'' derives from the fact that it was used when hauling field artillery into position.

Slipped Loop
In knot tying, a bight is a curved section or slack part between the two ends of a rope, string, or yarn.. "Any slack part of a rope between the two ends, particularly when curved or looped." A knot that can be tied using only the bight of a rope, without access to the ends, is described as in the bight. The term "bight" is also used in a more specific way when describing Turk's head knots, indicating how many repetitions of braiding are made in the circuit of a given knot. Bight vs. open loop Sources differ on whether an open loop or U-shaped curve in a rope qualifies as a bight. treats bights and loops as distinct, stating that a curve "no narrower than a semicircle" is a bight, while an open loop is a curve "narrower than a bight but with separated ends". However, ''The Illustrated Encyclopedia of Knots'' (2002) states: "Any section of line that is bent into a U-shape is a bight."

Angler's Loop
An angler's loop, otherwise known as a perfection loop, is a type of knot which forms a fixed loop. Useful for fine or slippery line, it is one of the few loop knots which holds well in bungee cord. It is quite secure, but it jams badly and is not suitable if the knot will need to be untied. Tying Angler's loop may be tied * alone and then used, ** it may be tied in the bight or at the working end ** it may be tied one handed ** it may be fashioned with several loops ** it may be locked for additional stability ** it may be tied at high speed in an emergency * it may be tied through an object (typically a ring).

Bowline On The Bight
The bowline on a bight is a knot which makes a pair of fixed-size loops in the middle of a rope. Its advantage is that it is reasonably easy to untie after being exposed to load. This knot can replace the figure-eight loop knot when tying into a climbing harness. It is one of the two tie-in knots that are being taught by the German Alpine Club (DAV), generally being considered secure. Dangers 2011 testing shows that the knot might slip when only one loop is loaded. Cavers and canyoneers ought to fasten their cow-tail carabiner through both loops. Video with genuine ''et voilà!'' ending European cavers widely advocate the use of a figure eight twisted version of the bowline on a bight. Applications This knot can be used to provide a toe hold in the middle of a rope; to make an emergency bosun's chair; and to create an upper rope "block" to make a crude purchase by threading the rope round an anchor point and then back up through the loop. It is sometimes used in sport climbi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Span Loop
A span loop is a non-jamming loop that can be tied away from the ends of the rope. Information The span loop is known for being extremely easy to untie. The beginning of tying this knot begins with tying a Half Sheepshank, which is also known as a Bell Ringer's Knot. In order to tie this, the same one-handed twist method employed for tying a bowline can be used. One bight or loop will poke up through the half-hitch, and it will perfectly match the end of the rope that is also poking up through the signature half-hitch part of a bowline as it is done with the one hand twist method. The next thing to do is to push the bottom loop back up and through the top loop.

Overhand Loop
The overhand loop is a simple knot which forms a fixed loop in a rope. Made by tying an overhand knot in the bight, it can be tied anywhere along a rope (does not need any working end). The knot can be used for attaching clips, hooks, other rope, etc., but has the disadvantage that it is likely to jam tight when the rope has been pulled and the knot may need to be cut off. It also has some uses in kite-flying, though other knots may be better. It is commonly disapproved by the Boy Scouts because of its tendency to be misused as an alternative to the bowline The bowline ( or ) is an ancient and simple knot used to form a fixed loop at the end of a rope. It has the virtues of being both easy to tie and untie; most notably, it is easy to untie after being subjected to a load. The bowline is sometimes ....

Figure-eight Loop
Figure-eight loop (also figure-eight on a bight, figure-eight follow-through, figure-eight retrace, Flemish loop, or Flemish eight) is a type of knot created by a loop on the bight. It is used in climbing and caving. The double figure eight is used to put a loop in the end of a rope, or around an object. It is relatively easy to tie and is secure, but can become difficult to untie after heavy loading, and can jam badly in any rope type. Tying methods On a bight A figure-eight loop is created by doubling the rope into a bight, then tying the standard figure-eight knot. In climbing, this knot is used to save time when repeatedly attaching the rope to climbing harnesses, using locking carabiners, such as when a group of people are climbing on the same top-rope. Follow-through Alternatively, to tie the knot directly around an object, the follow-through method must be used. * Tie a regular figure eight knot with a significant amount of extra tail. * Loop the tail around the o ...

Sheep Shank
A shank is a type of knot that is used to shorten a rope or take up slack, such as the sheepshank. The sheepshank knot is not stable. It will fall apart under too much load or too little load. The knot has several features which allow a rope to be shortened: * It provides two loops, one at each end of the knot which can be used to pass another rope through * The knot remains somewhat secure under tension; the coarser the rope the more secure it is (see Disadvantages, below) * The knot falls apart easily when tension is removed Construction methods A sheepshank knot may be constructed as follows: ... * Pull a section of rope back and lay it alongside the rope, so that the rope forms a Z approximately 20 cm long. * Flatten the Z so that there are 3 sections of rope lying alongside each other, with two U-bends where the rope reverses direction. * At each U-bend, grasp the U-bend in one hand, thus holding two of the rope sections. With the other hand form a small loop in the r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Half Hitch
The half hitch is a simple overhand knot, where the working end of a line is brought over and under the standing part. Insecure on its own, it is a valuable component of a wide variety of useful and reliable hitches, bends, and knots. Two successive half hitches tied around an object makes up the common clove hitch. Two successive half hitches tied around the standing part of a rope is known as two half-hitches or double half hitch. One instance where a half hitch stands on its own without additional embellishment is when added to a timber hitch to help stabilize a load in the direction of pull. A timber hitch is tied on the far end of the load to bind it securely and a half hitch made at the forward end to serve as a guide for the rope. In this instance, the half hitch combined with a timber hitch is known as a killick hitch or kelleg hitch. The knot is attractive to the eye and so is used decoratively for French whipping which is also known as ''half hitch whipping''. S ...

Figure-eight Knot
The figure-eight knot or figure-of-eight knot is a type of stopper knot. It is very important in both sailing and rock climbing as a method of stopping ropes from running out of retaining devices. Like the overhand knot, which will jam under strain, often requiring the rope to be cut, the figure-eight will also jam, but is usually more easily undone than the overhand knot. The stevedore knot is the figure-eight knot with two half twists added before the end is finally stuck. Different types Figure-eight loop The figure-eight loop is used like an overhand loop knot. This type of knot can be used in prusik climbing when used in conjunction with a climbing harness, a climbing rope, and locking carabiner designed for climbing, to ascend or descend with minimal equipment and effort. Figure-eight bend The figure-eight bend knot is used to " splice" together two ropes, not necessarily of equal diameter. This knot is tied starting with a loose figure-eight knot on one rope ...
