Camalot Number 6
Camalot is a brand of spring-loaded camming devices manufactured by Black Diamond Equipment used to secure ropes while rock climbing. Camalots use a dual-axle system, resulting in a slightly higher expansion range than similarly sized single axle units, however that results in significant weight penalty. Dual-axel was patented and for decades was only used by Black Diamond, however the patent has expired in 2005 and several other manufacturers began producing dual-axel cams, often also replicating Camalots sizes and coloring. Most notable Camelot look-alikes include DMM Dragons and Wild Country's New Friends. Like other cams, Camalot lobes are in the shape of a logarithmic spiral A logarithmic spiral, equiangular spiral, or growth spiral is a self-similar spiral curve that often appears in nature. The first to describe a logarithmic spiral was Albrecht Dürer (1525) who called it an "eternal line" ("ewige Linie"). More ..., resulting in a constant angle between the cam a ...

Spring-loaded Camming Device
A spring-loaded camming device (also SLCD, cam or friend) is a piece of rock climbing or mountaineering protection equipment. It consists of two, three, or four cams mounted on a common axle or two adjacent axles, so that pulling on the axle forces the cams to spread farther apart. This is then attached to a sling and carabiner at the end of the stem. The SLCD is used by pulling on the "trigger" (a small handle) so the cams retract together, then inserting it into a crack or pocket in the rock and releasing the trigger to allow the cams to expand. A pull on the rope, such as that generated by a climber falling, will cause a properly placed SLCD to convert the pulling force along the stem of the unit into outwards pressure on the rock, generating massive amounts of friction and preventing the removal of the unit from the rock. Because of the large forces which are exerted on the rock when an SLCD is fallen on, it is very important that SLCDs are only placed in solid, strong ...

Black Diamond Equipment
Black Diamond Equipment is a manufacturer of equipment for climbing, skiing, and mountain sports, based in Utah, United States. The company also has a global office in Innsbruck, Austria. The company is owned by Clarus Corporation, which also owns Pieps, ClimbOn! Skincare, and Sierra Bullets. History Black Diamond Equipment's history dates from the late 1950s, when climber Yvon Chouinard began hand-forging pitons and selling them from the trunk of his car in Yosemite Valley. Chouinard's pitons quickly gained a reputation for quality, and Chouinard Equipment was born soon after in Ventura, California. In early 1989, after several product-liability lawsuits and a continued lack of profitability, Yvon Chouinard placed the company in Chapter 11 bankruptcy. Black Diamond was founded on December 1, 1989, when the assets of Chouinard Equipment Ltd. were purchased by a group of former company employees led by (now former CEO) Peter Metcalf, and a few outside investors.

Rock Climbing
Rock climbing is a sport in which participants climb up, across, or down natural rock formations. The goal is to reach the summit of a formation or the endpoint of a usually pre-defined route without falling. Rock climbing is a physically and mentally demanding sport, one that often tests a climber's strength, endurance, agility and balance along with mental control. Knowledge of proper climbing techniques and the use of specialized climbing equipment is crucial for the safe completion of routes. Because of the wide range and variety of rock formations around the world, rock climbing has been separated into several different styles and sub-disciplines, such as scrambling, bouldering, sport climbing, and trad (traditional) climbing another activity involving the scaling of hills and similar formations, differentiated by the rock climber's sustained use of hands to support their body weight as well as to provide balance. Rock climbing competitions have the objectives of e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wild Country (company)
Wild Country is a major manufacturer of rock climbing equipment, and is most noted for introducing the ''Friend'', a spring-loaded camming device. The company is based in Tideswell in the English Peak District, close to some of the UK's most popular climbing areas. Wild Country was founded in 1977 by British climber Mark Vallance, after he met American climber Ray Jardine who had made and used prototypes of the camming devices he had invented but could find nobody to produce them in volume. Vallance was convinced of their commercial potential and, with the collaboration of Jardine, set up a factory in the Peak District to manufacture the devices which they had for a long time called Friends. Friends, though expensive, became immediately popular with climbers, selling over 5 thousand units in the first year, and establishing Wild Country as a major climbing gear manufacturer. Soon the company started expanding its range which now includes climbing harnesses, nuts, carabiners, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Logarithmic Spiral
A logarithmic spiral, equiangular spiral, or growth spiral is a self-similar spiral curve that often appears in nature. The first to describe a logarithmic spiral was Albrecht Dürer (1525) who called it an "eternal line" ("ewige Linie"). More than a century later, the curve was discussed by Descartes (1638), and later extensively investigated by Jacob Bernoulli, who called it ''Spira mirabilis'', "the marvelous spiral". The logarithmic spiral can be distinguished from the Archimedean spiral by the fact that the distances between the turnings of a logarithmic spiral increase in geometric progression, while in an Archimedean spiral these distances are constant. Definition In polar coordinates (r, \varphi) the logarithmic spiral can be written as r = ae^,\quad \varphi \in \R, or \varphi = \frac \ln \frac, with e being the base of natural logarithms, and a > 0, k\ne 0 being real constants. In Cartesian coordinates The logarithmic spiral with the polar equation r = a e^ c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black Diamond Camalot - 06
Black is a color which results from the absence or complete absorption of visible light. It is an achromatic color, without hue, like white and grey. It is often used symbolically or figuratively to represent darkness. Black and white have often been used to describe opposites such as good and evil, the Dark Ages versus Age of Enlightenment, and night versus day. Since the Middle Ages, black has been the symbolic color of solemnity and authority, and for this reason it is still commonly worn by judges and magistrates. Black was one of the first colors used by artists in Neolithic cave paintings. It was used in ancient Egypt and Greece as the color of the underworld. In the Roman Empire, it became the color of mourning, and over the centuries it was frequently associated with death, evil, witches, and magic. In the 14th century, it was worn by royalty, clergy, judges, and government officials in much of Europe. It became the color worn by English romantic poets, businessmen an ...

7075 Aluminium Alloy
7075 aluminium alloy (AA7075) is an aluminium alloy with zinc as the primary alloying element. It has excellent mechanical properties and exhibits good ductility, high strength, toughness, and good resistance to fatigue. It is more susceptible to embrittlement than many other aluminium alloys because of microsegregation, but has significantly better corrosion resistance than the alloys from the 2000 series. It is one of the most commonly used aluminium alloys for highly stressed structural applications and has been extensively used in aircraft structural parts. 7075 aluminium alloy's composition roughly includes 5.6–6.1% zinc, 2.1–2.5% magnesium, 1.2–1.6% copper, and less than a half percent of silicon, iron, manganese, titanium, chromium, and other metals. It is produced in many tempers, some of which are 7075-0, 7075-T6, 7075-T651. The first 7075 was developed in secret by a Japanese company, Sumitomo Metal, in 1935, but reverse engineered by Alcoa in 1943, after e ...

Climbing Gear - Camalot Cams - 04
Climbing is the activity of using one's hands, feet, or any other part 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, and for competition, and is also done in trades that rely on ascension; such as emergency rescue and military operations. Climbing is done indoors and outdoors and on natural (e.g. rock and ice) and artificial surfaces. Professional mountain guides or rock climbing guides (e.g. the UIAGM), were a significant element in developing the popularity of the sport in the natural environment, and remain so today. Since the 1980s, the development of competition climbing and the availability of artificial climbing walls have dramatically increased the popularity of rock climbing as a sport and led to the emergence of professional rock climbers, such as Wolfgang Güllich, Chris Sharma, Lynn Hill and Catherine D ...
