Feb 23, 2020 · The UIAA measures static elongation, which is how much a rope stretches while dangling a standard 80 kg weight. Added flexibility does not lower strength with a whopping 9,107 lbf published tensile. ultrasonic ending eliminates the sheath slippage possible to be produced with one or two stitched eyes at the end of the rope available in 3 There are many things to take into consideration when selecting a climbing rope; diameter, length, static vs. INDUS 10,5 mm Static Rope is a robust and reliable choice for those who demand strength and durability in their outdoor pursuits. Higher static elongation generally indicates less efficiency because energy is wasted through rope stretch. The useful static elongation is tested by applying a load of 80 kg to the rope and shall not exceed 10% for single ropes (single-strand ropes) and twin ropes (two strands tested at the same time) and 12% for half ropes (single strand). SafetyPro Static ropes designed to meet the needs of rope access personnel. Jul 29, 2020 · Static ropes have much less twist in the core than dynamic ropes, creating a rope with much less elongation. This design evolved into the current BlueWater II Plus series of low elongation/static ropes. This is most important when you are talking about potential ground falls right off the deck. A fall on static rope with little elongation and a fixed anchor point will generate much higher impact forces than a fall on dynamic rope using a running belay.

Discover the differences between them, from construction to use cases, in this informative article. comLow-elongation or static, ropes are a core element of any work-at-height system. These ropes are also known under the term of semi-static or low-elongation ropes. The minimum elongation enables the effortless climbing of the rope making it an ideal companion when working at heights. The number one choice for precise work on and with ropes. The special kernmantle construction maintains high tensile strength with minimum elongation. 5mm ropes. The test is done on one strand for single and half rope, two strands for twin rope. The low elongation of maximum 5% is truly advantageous for static ropes because it makes the use of pulleys and ascenders much more convenient and efficient. These and other factors should be taken into account when choosing and rigging a static or low stretch rope. dynamic, dry treatment, bi-pattern, impact force, elongation the list goes on. This low elasticity makes it unsuitable for arresting dynamic falls but ideal for applications like Search & Rescue, Life Safety events. e. The low residual elongation furthermore enables precise work when rigging (rescue) loads and during work positioning. During this secondary creep phase, the line may have to be re-tensioned periodically over the service life of the line (years).

KM III Max is a well-balanced and low rotating static rope featuring a unique twill design that ensures work positioning with smooth descents. In phase two, the rope undergoes a slow, steady rate of elongation (a few percent per year assuming a constant, static load). ASSAULTLINE® is THE original low visibility, low elongation/static rope. Ropes with such low elongation qualities are often referred to as true static or super static. The standard diameter provides a good grip for easier handling. These include abseiling, rappelling, fire rescue, caving, and working at heights. Edelrid Performance Static Rope combines superb abrasion resistance and low elongation with excellent handling. The standard diameter of the AXIS Static Rope ensures a good grip for easier handling. The minimal stretch of the rope is advantageous for these purposes. Rope manufacturers specify the elasticity of a climb rope by the fractional static elongation s defined by s = x/L where x is the change in length of a rope when a standard mass ms of 80 kg is hung on it and L is the original length of the rope. It is limited to: 10 % for single ropes (one strand of rope) 12 % for half ropes (one strand of rope) 10 % for twin ropes (two strands of rope) In use, static elongation is important mainly in a slingshot top rope situation Jan 16, 2025 · Low Elongation: Static ropes typically stretch less than 5% under a standard load, making them ideal for situations where stability is essential. Furthermore, it’s essential to understand the difference between dynamic and static ropes. The Sterling name has become synonymous with durability and reliability across multiple industries at all job sites.

Xstatic provides better control for sleek descents and makes retrieval smooth and easy even with multiple redirects. Attempts to execute SRT or DSRT on dynamic rope supported by a conventional tree crotch support does works fine, but will be uncomfortable amount of stretch or bounce. A static rope is a low-elongation rope that is designed to stretch minimally when placed under load, typically less than 5%. To prevent unwanted twisting and kinking in the rope, some of the core strands are twisted in one direction, while the others are twisted the opposite way. The GTR is an ultra-low elongation semi-static rope designed with 100% polyester fiber. Dynamic ropes have high elongation capacity, while static ropes exhibit minimal stretch under load. Though it may vary by brand, most static ropes come in black and white while dynamic ropes are often more shiny and colorful. low stretch rope type A designed for rope access, positioning, rescue or rigging. Features a 48 carrier sheath and extremely supple handling. A low-stretch rope would have 6% to 10% elongation at 10% of the rope’s MBS. Elongation describes how much a rope will stretch when it is loaded, either by being pulled slowly or when suddenly loaded with an impact force. 7 6,114 Sheath Proper rappelling and belaying techniques - Fast rappels, bounding or swinging, positioning the rope over a sharp edge, dynamically loading a low elongation / static rope are some of the examples of uses that damage your rope and will cause failure and injury or death. Mar 24, 2025 · Although all canyoneering ropes are "static" in that they are not designed to absorb large shock loads like dynamic climbing ropes, some are more static than others.

Static: A rope whose maximum elongation is less than 6% at 10% of its minimum breaking strength. Unlike dynamic ropes, which can be used as climbing safety lines, static ropes are lower-stretch, and are therefore used for hauling gear, descending and rope access. In most climbing situations, a dynamic rope must be used or you risk severe consequences such as shock-loading, personal injury, and/or anchor systems failure. Description This excellent rope with low elongation and high static strenght is intended primarily for work at height and for securing people above vertical drops. BOTH MEASUREMENTS ARE IMPORTANT BECAUSE THEY CAN AFFECT THE AMOUNT OF IMPACT FORCE THAT IS TRANSMITTED TO THE CLIMBER DURING A FALL, AS WELL AS THE AMOUNT OF ROPE THAT ELONGATES UNDER CONSTANT TENSION.

Dynamic elongation and static elongation are two different items. com Elongation describes how much a rope will stretch when it is loaded, either by being pulled slowly or when suddenly loaded with an impact force. The less stretch a canyoneering rope has, the better; there are few to no good reasons to have a stretchy canyoneering rope. Today our ropes still set the world standard in quality, design and durability. Available in two highly visible contrasting colors for easy identification. While dynamic rope is ideal for climbing where the bounce is needed to catch a climber in a fall, static rope works for a purpose. Static elongation refers to the stretch observed under a constant load, whilst dynamic elongation refers to the stretch during a sudden load, like a fall. UIAA 107 Low Stretch Ropes (same as EN 1891) is often mistaken for a static rope standard, and many people often refer to low stretch ropes as “static” or sometimes “semi-static”.
