Body Belay
In climbing and mountaineering, belaying comprises techniques used to create friction within a climbing protection system, particularly on a climbing rope, so that a falling climber does not fall very far. A climbing partner typically applies tension at the other end of the rope whenever the climber is not moving, and removes the tension from the rope whenever the climber needs more rope to continue climbing. The belay is the place where the belayer is anchored, which is typically on the ground, or on ledge (where it is also called a belay station) but may also be a hanging belay where the belayer themself is suspended from an anchor in the rock on a multi-pitch climb. Description Belaying is a critical part of climbing safety. Correct belaying methods allow a belayer to hold the entire weight of the climber with relatively little force and easily arrest falls. In its simplest form, a belay consists of a rope that runs from a climber to another person (the belayer) who c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red Rocks - Climbers On Physical Graffiti - 5
Red is the color at the long wavelength end of the visible spectrum of light, next to Orange (colour), orange and opposite Violet (color), violet. It has a dominant wavelength of approximately 625–750 nanometres. It is a primary color in the RGB color model and a secondary color (made from magenta and yellow) in the CMYK color model, and is the complementary color of cyan. Reds range from the brilliant yellow-tinged Scarlet (color), scarlet and Vermilion, vermillion to bluish-red crimson, and vary in shade from the pale red pink to the dark red burgundy (color), burgundy. Red pigment made from ochre was one of the first colors used in prehistoric art. The Ancient Egyptians and Mayan civilization, Mayans colored their faces red in ceremonies; Roman Empire, Roman generals had their bodies colored red to celebrate victories. It was also an important color in China, where it was used to color early pottery and later the gates and walls of palaces. In the Renaissance, the brillian ...

Capstan Equation
The capstan equation or belt friction equation, also known as Euler–Eytelwein formula (after Leonhard Euler and Johann Albert Eytelwein), relates the hold-force to the load-force if a flexible line is wound around a cylinder (a bollard, a winch or a Capstan (nautical), capstan). It also applies for fractions of one turn as occur with rope drives or band brakes. Because of the interaction of frictional forces and tension, the tension on a line wrapped around a capstan may be different on either side of the capstan. A small ''holding'' force exerted on one side can carry a much larger ''loading'' force on the other side; this is the principle by which a capstan-type device operates. A holding capstan is a ratchet device that can turn only in one direction; once a load is pulled into place in that direction, it can be held with a much smaller force. A powered capstan, also called a winch, rotates so that the applied tension is multiplied by the friction between rope and caps ...

High Ropes Course
A ropes course is a challenging outdoor personal development and team building activity which usually consists of high elements, low elements, or some combination of the two. Low elements take place on the ground or above the ground. High elements are usually constructed in trees or made of utility poles and require a belay for safety. Terminology Ropes courses are referred to using several different names, including Challenge Courses, Ropes Challenge Courses, Teams Course, and Low Ropes, as well as more idiosyncratic names such as the Challenging Outdoor Personal Experience ( Project COPE) course (used by the Boy Scouts of America). An Aerial Adventure Park (or "European-Style" Adventure Park, Tree-Top Adventure course) has a more recreational purpose. Other related terms include obstacle courses, assault courses and commando courses, although these terms also have slightly different meanings, often more associated with military training than with education and trainin ...

Carabiner
A carabiner or karabiner (), often shortened to biner or to crab, colloquially known as a (climbing) clip, 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 word comes from the German language, German , short for , meaning "carbine hook," as the device was used by carabiniers to attach their carbines to their belts. Use Carabiners are widely used in rope-intensive activities such as climbing, fall arrest systems, arboriculture, caving, sailing, hot air ballooning, hot-air ballooning, rope rescue, construction, industrial rope access, industrial rope work, window cleaning, whitewater rescue, and acrobatics. They are predominantly made from both steel and aluminium. Those used in sports tend to be of a lighter weight than those used in commercial applications and rope rescue. Often referred to as carabiner-style or as mini-carabiners, carabiner keyrings and ot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Munter Hitch
The Munter hitch, also known as the Italian hitch, mezzo barcaiolo is a simple adjustable knot, commonly used by climbers, cavers, and rescuers to control friction in a life-lining or belay system. It is often mistakenly identified as the crossing hitch, however in the cross hitch the line does not return along its original path. To climbers, this hitch is also known as HMS, the abbreviation for the German term , meaning ''half clove hitch belay''. This technique can be used with a special "pear-shaped" HMS locking carabiner, or any locking carabiner wide enough to take two turns of the rope. In the late 1950s, three Italian climbers, Mario Bisaccia, Franco Garda and Pietro Gilardoni developed a new belay technique called the "Mezzo Barcaiolo" (MB) meaning; "a half of the knot, which is used by the sailors to secure a boat to a bollard in a harbor." The "MB" came to be known as the Munter hitch after Werner Munter, a Swiss mountain guide popularized its use in mountaineeri ...

Multi-pitch Climbing
Multi-pitch climbing is a type of climbing that typically takes place on climbing routes, routes that are more than a single rope length (circa 50 to 70 metres) in height (or distance), and thus where the lead climber cannot complete the climb as a single pitch (climbing), pitch. Where the number of pitches exceeds 6–10 (300–500 metres), it can become big wall climbing, or where the pitches are in a mixed rock and ice mountain environment, it can become alpine climbing. Multi-pitch rock climbs can come in traditional climbing, traditional, sport climbing, sport, and aid climbing, aid formats. Some have free soloed multi-pitch routes. Multi-pitch climbing is more complex and riskier than single-pitch climbing as the climbers will remain exposed on the route (e.g. a rock climbing route, an ice climbing, or a mixed climbing route) for longer, and it will often involve the use of hanging belays, long abseils, and the creation of belay anchors. Rescues from multi-pitch climbs are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
