Sling (climbing Equipment)
A sling or runner is an item of climbing equipment consisting of a tied or sewn loop of webbing. These can be wrapped around sections of rock, hitched to other pieces of equipment, or tied directly to a tensioned line using a Prusik style knot. They may be used as anchors, to extend an anchor to reduce rope drag, in anchor equalization, or to climb a rope. Types Slings come both sewn to length and assembled from loose webbing knotted as desired. Common sewn lengths include , , , and . They are available in widths of . Webbing for slings, also known as ''tape'', is sold off the reel, cut to length with a hot knife to prevent fraying, and tied as desired with a water knot. Sewn slings have a rated breaking strength of at least . Short sewn slings are a component of quickdraws, sometimes known as ''dogbones''. Traditionally, slings have been made of nylon. Increasingly, ultra high molecular weight polyethylene sold under the brand names Dyneema, Dynex and Spectra is used. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Climbing Equipment
A wide range of equipment is used during rock or any other type of climbing that includes equipment commonly used to protect a climber against the consequences of a fall. Rope, cord and webbing Climbing ropes are typically of kernmantle construction, consisting of a core (kern) of long twisted fibres and an outer sheath (mantle) of woven coloured fibres. The core provides about 70% of the tensile strength, while the sheath is a durable layer that protects the core and gives the rope desirable handling characteristics. Ropes used for climbing can be divided into two classes: dynamic ropes and low elongation ropes (sometimes called "static" ropes). Dynamic ropes are designed to absorb the energy of a falling climber, and are usually used as belaying ropes. When a climber falls, the rope stretches, reducing the maximum force experienced by the climber, their belayer, and equipment. Low elongation ropes stretch much less, and are usually used in anchoring systems. They are al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hitch Knot
A hitch knot is a type of knot used to secure a rope to an object or another rope. It is used in a variety of situations, including climbing, sailing, and securing loads. Hitch knots are classified based on their ability to be tightened or released, their resistance to slipping, and their strength. Some common types of hitch knots include the fisherman's knot, the water knot, and the clove hitch. Hitch knots are important because they allow a rope to be securely fastened to an object, enabling the rope to support weight or transmit force. Physical theory of hitches A simple mathematical theory of hitches has been proposed by Bayman and extended by Maddocks and Keller. It makes predictions that are approximately correct when tested empirically. Alphabetical list of hitch knots See also * List of knots * Single hitch A turn is one round of rope on a pin or cleat, or one round of a coil. Turns can be made around various objects, through rings, or around the standing part o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prusik
A Prusik ( ) is a friction hitch or knot used to attach a loop of cord around a rope, applied in climbing, canyoneering, mountaineering, caving, rope rescue, ziplining, and by arborists. The term Prusik is a name for both the loops of cord used to tie the hitch and the hitch itself, and the verb is "to prusik" (using a Prusik to ascend). More casually, the term is used for any friction hitch or device that can grab a rope (see autoblock). Due to the pronunciation, the word is often misspelled Prussik, Prussick, or Prussic. The Prusik hitch is named after its putative inventor, Austrian mountaineer Karl Prusik. It was shown in a 1931 Austrian mountaineering manual for rope ascending. It was used on several mountaineering routes of the era to ascend the final summit, where a rope could be thrown over the top and anchored so that climbers could attain the summit by prusiking up the other side of the rope. A Prusik made from cord does little or no damage to the rope it is attached t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rope Drag
A rope is a group of yarns, plies, fibres, or strands that are twisted or braided together into a larger and stronger form. Ropes have tensile strength and so can be used for dragging and lifting. Rope is thicker and stronger than similarly constructed cord, string, and twine. Construction Rope may be constructed of any long, stringy, fibrous material, but generally is constructed of certain natural or synthetic fibres. Synthetic fibre ropes are significantly stronger than their natural fibre counterparts, they have a higher tensile strength, they are more resistant to rotting than ropes created from natural fibres, and they can be made to float on water. But synthetic ropes also possess certain disadvantages, including slipperiness, and some can be damaged more easily by UV light. Common natural fibres for rope are Manila hemp, hemp, linen, cotton, coir, jute, straw, and sisal. Synthetic fibres in use for rope-making include polypropylene, nylon, polyesters (e.g. PET ...

The Freedom Of The Hills
''Mountaineering: The Freedom of the Hills'' is often considered the standard textbook for mountaineering and climbing in North America. The book was first published in 1960 by The Mountaineers of Seattle, Washington. The book was written by a team of over 40 experts in the field. The book grew out of the annual climbing course run since 1935 by the Mountaineers, for which the reading material was originally a combination of European works and lecturers' mimeo outlines. These were assembled into the ''Climber's Notebook'' and published by the Mountaineers as the hardbound ''Mountaineers Handbook'' in 1948. By 1955 the rapid postwar evolution of climbing techniques and tools had made the ''Handbook'' out of date, and the effort was begun to produce ''Freedom of the Hills''. Nearly 80 major contributors are credited in the first edition and were organized by a committee of 8 editors. The first four editions were only available in hardcover.

Water Knot
The water knot (also tape knot, ring bend, grass knot, or overhand follow-through) is a knot frequently used in climbing for joining two ends of webbing together, for instance when making a sling. Tying It is tied by forming an overhand knot in one end and then following it with the other end, feeding in the opposite direction. The ends should be left at least long and the knot should be "set" by tightening it with full body weight. The ends can be knotted, taped or lightly sewn to the standing parts to help prevent them from creeping back into the knot.Craig Luebben, ''Knots for Climbers'' (Evergreen, Colorado: Chockstone Press, 1993), 19. Uses The knot can be used for joining flat materials such as leather or tape.John 'Lofty' Wiseman SAS ''Survival Handbook, Revised Edition''; William Morrow Paperbacks (2009) Security Once tied, for additional security each end should be tied in a double overhand stopper knot around the other standing end.

A quickdraw (also known as an extender) is a piece of climbing equipment used by rock and ice climbers to allow the climbing rope to run freely through protection such as a bolt anchors or other traditional gear while leading. A quickdraw consists of two carabiner A carabiner or karabiner () is a specialized type of shackle, a metal loop with a spring-loaded gate used to quickly and reversibly connect components, most notably in safety-critical systems.

The other carabiner is for the climbing rope, and uses a bent gate. Quickdraws are manufactured with either a solid carabiner gate or a wire carabiner gate for its lighter weight.
