Webbing
file:Webbing.jpg, red, blue and black nylon webbing as used in auto racing harnesses Webbing is a strong Textile, fabric weaving, woven as a flat strip or tube of varying width and fibres, often used in place of rope. It is a versatile component used in climbing, slacklining, furniture manufacturing, automobile safety, auto racing, tow truck, towing, parachuting, Combat uniform, military apparel, load securing, and many other fields. It may be made of Hemp#Fiber, hemp, cotton or linen, but also synthetic fibers such as nylon, polypropylene or polyester. Webbing is also made from exceptionally high-strength material, such as Dyneema, and Kevlar. Webbing is both light and strong, with Ultimate tensile strength, breaking strengths readily available in excess of . There are two basic constructions of webbing. Flat webbing is a solid weave, with seat belts and most backpack straps being common examples. Tubular webbing consists of a flattened tube, and is commonly used in climbing a ...

Seat Belt
A seat belt, also known as a safety belt or spelled seatbelt, is a vehicle safety device designed to secure the driver or a passenger of a vehicle against harmful movement that may result during a collision or a sudden stop. A seat belt reduces the likelihood of death or serious injury in a traffic collision by reducing the force of secondary impacts with interior strike hazards, by keeping occupants positioned correctly for maximum effectiveness of the airbag (if equipped), and by preventing occupants being ejected from the vehicle in a crash or if the vehicle rolls over. When in motion, the driver and passengers are traveling at the same speed as the vehicle. If the vehicle suddenly halts or crashes, the occupants continue at the same speed the vehicle was going before it stopped. A seat belt applies an opposing force to the driver and passengers to prevent them from falling out or making contact with the interior of the car (especially preventing contact with, or going ...

Rock Climbing Equipment
Rock-climbing equipment varies with the specific type of rock climbing, climbing that is undertaken. Bouldering needs the least equipment outside of climbing shoes, Chalk (climbing), climbing chalk and optional Bouldering mat, crash pads. Sport climbing adds climbing rope, ropes, climbing harness, harnesses, belay devices, and quickdraws to clip into pre-drilled Bolt (climbing), bolts. Traditional climbing adds the need to carry a "rack" of temporary passive and active #Protection devices, protection devices. Multi-pitch climbing, and the related big wall climbing, adds devices to assist in ascending and descending fixed ropes. Finally, aid climbing uses unique equipment to give mechanical assistance to the climber in their upward movement (e.g. aiders). Advances in equipment are a key part of the history of rock climbing, rock climbing history, starting with the climbing rope. Modern devices enable climbers to perform tasks previously done manually, with greater control – ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slacklining
Slacklining is walking, running or balance (ability), balancing along a suspended length of flat webbing that is tension (physics), tensioned between two anchor (climbing), anchors. Slacklining is similar to Slackwire#Slack rope, slack rope walking and tightrope walking. Slacklines differ from tightwires and tightropes in the type of material used and the amount of tension applied during use. Slacklines are tensioned significantly less than tightropes or tightwires in order to create a dynamic line which will stretch and bounce like a long and narrow trampoline. Tension can be adjusted to suit the user, and different webbing may be used in various circumstances. Styles of slacklining Tricklining Tricklining has become the most common form of slacklining because of the easy setup of slackline kits. Tricklining is often done low to the ground but can be done on highlines as well. A great number of tricks can be done on the line, and because the sport is fairly new, there is plent ...

Climbing Harness
A climbing harness is a piece of equipment that allows a climber to tie in (climbing), tie in to the safety of a rope. It is used in climbing, rock and ice climbing, ice climbing, abseiling, and lowering; this is in contrast to other activities requiring ropes for access or safety such as industrial rope work (such as window cleaning), construction, and rescue and recovery, which use safety harnesses instead. Overview While an improvised harness can be created out of a length of rope or nylon webbing, commercially produced harnesses specific to climbing rock and ice are the norm. These characteristically include a dedicated tie-in loop, padding, and amenities such as gear loops. Most commercial climbing harnesses meet the guidelines and manufacturing standards of organizations such as the Union Internationale des Associations d'Alpinisme (UiAA) or European Committee for Standardization. Harnesses of users involved in climbing should be attached to dynamic (kernmantle) rope, whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sling (climbing Equipment)
A sling 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. Uses In 1957 Jan and Herb Conn wrote an article titled "the versatile runner" with a long list of uses, which is still quite accurate: # Slings and now more often 3-foot alpine draws or shorter quickdraws are used in-between pieces of protection and the rope to minimize rope drag # Hitch around a chock stone or a tree to use as passive protectionConn, Jan and Herb (November 1957). ''The versatile runner'' - Summit (PDF) # Clove hitch around chicken heads or sling around horns # Longer slings or cordelettes can be used for equalized belay stations # Slings can be used as improvised "personal anchor system" attaching climber di ...

Dyneema
Ultra-high-molecular-weight polyethylene (UHMWPE, UHMW) is a subset of the thermoplastic polyethylene. Also known as high-modulus polyethylene (HMPE), it has extremely long chains, with a molecular mass typically between 2 and 6 million amu. The longer chain serves to transfer load more effectively to the polymer backbone by strengthening intermolecular interactions. This results in a very tough material, with the highest impact strength of any thermoplastic presently made. UHMWPE is odorless, tasteless, and nontoxic. It embodies all the characteristics of high-density polyethylene (HDPE) with the added traits of being resistant to concentrated acids and alkalis, as well as numerous organic solvents. It is highly resistant to corrosive chemicals except oxidizing acids; has extremely low moisture absorption and a very low coefficient of friction; is self-lubricating (see boundary lubrication); and is highly resistant to abrasion, in some forms being 15 times more resistant to a ...

Load Securing
Load securing, also known as cargo securing, is the securing of cargo for transportation. According to the European Commission Transportation Department "it has been estimated that up to 25% of accidents involving trucks can be attributable to inadequate cargo securing". Cargo that is improperly secured can cause severe accidents and lead to the loss of cargo, lives, and vehicles, or cause environmental hazards. Background Because of globalization, the subsequent flow of goods that are transported over greater distances, containerization and new regulatory measures has led to a greater demand for efficient, cost effective and environmentally friendly cargo restraint products. Many types of cargo such as corrugated fiberboard boxes are often formed into a unit load. This often consists of items on a pallet unitized by stretch wrap, shrink wrap, pressure-sensitive tape, or strapping. Larger shipping containers such as crates are often on skids and are ready for loading. Thes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Climbing
Climbing is the activity of using one's hands, feet, or other parts of the body to ascend a steep topographical object that can range from the world's tallest mountains (e.g. the eight thousanders) to small boulders. Climbing is done for locomotion, sporting recreation, for competition, and is also done in trades that rely on ascension, such as construction and military operations. Climbing is done indoors and outdoors, on natural surfaces (e.g. rock climbing and ice climbing), and on artificial surfaces (e.g. climbing walls and climbing gyms). The sport of climbing evolved by climbers making first ascents of new types of climbing routes, using new climbing techniques, at ever-increasing grades of difficulty, with ever-improving pieces of climbing equipment. Guides and guidebooks were an important element in developing the popularity of the sport in the natural environment. Early pioneers included Walter Bonatti, Riccardo Cassin, Hermann Buhl, and Gaston Rébuffat, wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polypropylene
Polypropylene (PP), also known as polypropene, is a thermoplastic polymer used in a wide variety of applications. It is produced via chain-growth polymerization from the monomer Propene, propylene. Polypropylene belongs to the group of polyolefins and is Crystallization of polymers#Degree of crystallinity, partially crystalline and Chemical polarity#Nonpolar molecules, non-polar. Its properties are similar to polyethylene, but it is slightly harder and more heat-resistant. It is a white, mechanically rugged material and has a high chemical resistance. Polypropylene is the second-most widely produced Commodity plastics, commodity plastic (after polyethylene). History Phillips Petroleum chemists J. Paul Hogan and Robert Banks (chemist), Robert Banks first demonstrated the polymerization of propylene in 1951. The stereoselective polymerization to the isotactic was discovered by Giulio Natta and Karl Rehn in March 1954. This pioneering discovery led to large-scale commercial producti ...

Weaving
Weaving is a method of textile production in which two distinct sets of yarns or threads are interlaced at right angles to form a fabric or cloth. Other methods are knitting, crocheting, felting, and braiding or plaiting. The longitudinal threads are called the warp and the lateral threads are the weft, woof, or filling. The method in which these threads are interwoven affects the characteristics of the cloth. Cloth is usually woven on a loom, a device that holds warp threads in place while filling threads are woven through them. A fabric band that meets this definition of cloth (warp threads with a weft thread winding between) can also be made using other methods, including tablet weaving, back strap loom, or other techniques that can be done without looms. The way the warp and filling threads interlace with each other is called the weave. The majority of woven products are created with one of three basic weaves: plain weave, satin weave, or twill weave. Woven cl ...

SuperFabric
SuperFabric is a cut and abrasion resistant material, and a registered trademark of Higher Dimension Materials, Inc. As a technical fabric, SuperFabric is created with a base fabric such as nylon, polyester, neoprene, crepe, etc. and is overlaid with tiny, hard guard plates in a specific pattern. Spacings between the guard plates allow a degree of flexibility, breathability and are small enough to keep most sharp objects from penetrating. This guard plate technology protects the base fabric and contributes to the durability of the material. The geometry, thickness, and size of the guard plates, as well as the base fabric, vary depending on industry requirements. Customized and optional properties include flame resistance and specialized grip. Properties Cut resistance SuperFabric materials have tiny raised guard plates to deflect sharp objects that would otherwise tear the underlying base fabric. These guard plates are advertised to act as a protective barrier contributi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
