Dynamic ropes

There are basically three different types of rope, each best suited for different applications, which are tested according to different standards.

Single Ropes

Single ropes are the most common type of ropes used. Depending upon diameter and length they can be used for most conditions. The main advantage is simple handling. A disadvantage is that only routes up to a half rope length high, with subsequent lowering or rappelling, can be climbed.Single ropes come in diameters of approximately 8,7 to 11 mm and weigh between 51 to 77 grams per meter. Single ropes, withstand at least five falls with an 80 kg mass

Twin Ropes

Twin ropes must only be used in  pairs and are clipped together into each piece of protection, as with single rope technique (= Twin rope technique). The two ropes offer redundancy and thus, increased safety in the case of shock loading over a sharp edge. They are therefore especially suited for alpine climbing or demanding routes where retreat may be necessary. They offer the highest safety margin and allow full length rappels. With diameters from approximately 7,5 to 8,5 mm and a weight of between 38 to 45 grams per meter they are, together, about as heavy as the heaviest single ropes. With standard testing the ropes must withstand 12 falls with an 80 kg mass.

Half (Double) Ropes

Half ropes, with regard to strength and weight, lie between single and twin ropes. They only offer standard safety when they are used as a pair. But here you have the choice between  twin rope technique, where both ropes run parallel through the protection and  half rope technique, where the «left» and «right» ropes run separately through different protection points. This technique allows friction to be reduced in the case where protection points are widely spread and reduces impact force. This is of benefit when climbing traditionally protected routes. A belay method which enables the independent control of each rope must be used. Half ropes are tested singly with a 55 kg mass and must withstand five standard falls. They come in diameters from 8 to 9 mm and weigh 41 to 55 grams per meter. In single strand form they are suitable to belay two seconds.

Balanced Rope Concept

The manufacture of a rope is always a compromise between a high number of standard falls and low weight, low impact force and reduced elongation. For years Mammut has pursued the philosophy of the Balanced Rope, which holds that an outstanding rope is not distinguished by a single outstanding characteristic, but by the optimally balanced sum of all its performance characteristics

Mammut DRY

SeguridadMáxima seguridad incluso en condiciones adversas: el recubrimiento de acabado en Coatingfinish™ del núcleo y de la cubierta da como resultado una cuerda DRY que casi no absorbe el agua y no se congela a bajas temperaturas. Incluso una cuerda DRY totalmente mojada (15 min. sumergida en agua) todavía resiste el 80 % del número de caídas normalmente reportadas.
DurabilidadEnorme durabilidad gracias al acabado de la cubierta y del núcleo: en las pruebas de tracción, las cuerdas DRY alcanzaron una resistencia a la abrasión 50 % más alta en comparación con las cuerdas con acabados convencionales del mismo diámetro.

AplicacionesLas cuerdas CLASSIC ofrecen alta calidad con una buena relación precio/rendimiento y son la primera opción para la escalada en roca en condiciones secas y para la escalada en interiores.

The intended use determines which rope is best. It therefore makes sense to have a number of different ropes that can be used according to the type of climb. So, for high friction use, such as working routes or, top roping, a rope with a higher sheath proportion is useful. For alpine use, especially with ice, a drytreated rope is recommended. With possible sharp edge loading, or for longer rappels, twin, or half ropes are the first choice. The following gives examples of typical usage, each with the specific performance characteristic required by the rope.

Alpine Rock Climbing

i.e. High Sierra, Bugaboos, Wind River Range.

As soon as more difficult rock with a uniform level of difficulty comes in to play – meaning that a fall is possible at any time, classic belaying from anchor to anchor is necessary. Whether single or double – respectively twin ropes are used, depends mainly upon whether rappelling, or down climbing will be undertaken. In broken terrain, shorter rope lengths can be sensible.

Long Ice and Mixed Routes

i.e. Moonflower Buttress, Walker Spur, Droites North face, difficult waterfalls.

Only half or twin ropes offer the highest safety margins and enable long rappels in difficult terrain. Dry-treatment, easy handling and low weight all help with quick, efficient rope management. Long rope lengths are particularly useful on ice routes where pitches can often be run together.

Ice Climbing / Dry tooling

i.e. Vail, Ouray.

The requirements are similar to those of sport climbing, though dry-treatment is essential. With bolted mixed routes a single rope can offer simpler handling, though in sharp edged rock terrain the safety margin given by twin ropes is welcome. On poorly protected mixed routes, as typically found in Scotland, the half rope technique reduces the load on the «safety chain».


i.e. Mt. Rainier, Denali, South America.

With classic tours in mixed terrain and single climbing pitches up to grade 4 or 5 it is usual to down climb rather than rappel. Here it is advantageous to use a single rope. Or, a doubled half rope length can be used, though then only half the ropes length can be used. A dry-treated rope is also recommended here.

Multi Pitch Sport Climbing

i.e. Mt. Charleston, Red Rocks, El Portrero Chico, Wenden, Verdon.

Twin rope and half rope techniques offer the best safety margins and full rappelling distances. Dry treatment is useful in changeable conditions. Sharp edge resistance is guaranteed by the appropriate ropes. (Half or twin ropes).

Sport Climbing

i.e. Rifle, Smith, Rumney, Thailand.

With frequent falls, a burly rope is important. The impact force can be reduced by a dynamic belay. Handling and weight should be optimized for performing at the edge. Longer ropes (70/80 m) are needed at many modern sport climbing areas to allow safe lower-offs. Climbing Gyms Climbing Gym surfaces wear a rope more quickly; sturdier ropes and thicker sheaths are an advantage.

Working routes with Frequent Falls

i.e. Training on a local crag.

Frequent falls cause extensive wear. Therefore, a «work horse» of a rope is required. Weight is less important than longevity.Top Roping / institutional UseTo combat lots of abrasion and hard wear, a tougher sheath construction is an advantage. As long as falls by the second only are possible, then, circumstances allowing, a half rope can also be used.

Big Wall Climbing

i.e. El Capitan, Baffin.

A single rope is most often used for big wall climbing, while a static rope is used to haul. It’s desirable to have a large safety margin and tough sheath.


i.e. Mountain rescue.

High safety reserves and low elasticity are the most important properties of a mountain rescue rope.

Static ropes

Rope core

The rope core is made of double twisted cabled yarns, which are processed in several work processes that are coordinated with each other.

Rope sheath

Cabled or parallel spooled yarns surround the core as a sheath braiding, in order to protect it from outside mechanical influences and to give the rope compact, practical handling.

Info Tex

Each of our ropes contains an inlay-band in the rope core with the most important rope data on it: producer, testing standard, rope type, production period, material.


The robust abrasion-resistant rope, where the highest demands of durability and competent use are necessary. This rope fulfils all the requirements of a static rope intended for intensive use.


The Kernmantel construction shows a high strength with regard to the correct, effective diameter, which corresponds exactly to the nominal diameter. Due to the extraordinarily robust and stableshaped rope construction, Mammut cords maintain optimum handling and use characteristics even after intensive use.Especially suited for:

Tecnologías de acabado

Tecnología Mammut® Coated Core

Los hilos centrales individuales se somenten a un proceso de acabado antes del trenzado con un recubrimiento Coatingfinish™ y mediante un proceso térmico. Este acabado proporciona a los hilos centrales una protección permanente eficaz contra la retención de agua y suciedad. Además, se reduce la fricción entre las capas centrales, con lo que se mejora su deslizamiento. En caso de una carga como por una caída, la acción de la fuerza se distribuye uniformemente en todas las capas y la cuerda puede desarrollar el rendimiento óptimo. La tecnología Mammut® Coated Core se utiliza exclusivamente en las cuerdas de la línea DRY.

Tecnología Mammut® Coated Sheath

La cubierta de la cuerda recibe, después del trenzado, un recubrimiento de sellado y, además, la cuerda recibe un tratamiento térmico. Este tratamiento térmico produce un aumento significativo del rendimiento: en comparación con una cuerda del mismo diámetro sin procesamiento adicional, pueden aguantar de 1 a 2 caídas estándar adicionales mientras sigue mostrando un manejo agradablemente suave. El sellado de la cuerda también aumenta la resistencia a la abrasión y le concede propiedades repelentes al agua y a la suciedad. La tecnología Mammut® Coated Sheath se utiliza en las cuerdas de la línea PROTECT y de la línea DRY.
