Conversion factors from one to the other are: Kg to kN x 0. Also fixed rope applications, hauling and lifting systems, and life safety applications can be well covered by KM III – a true jack-of-all-trades. It generally has a high breaking strength coupled with a good abrasion resistance. Knots in the rope can reduce the strength by 50%. The weaker rope will work harder and as a result will have to be retired sooner. The minimum breaking load for ropes required under EN 1891A is 22kN.

Even type IV (750) paracord is too weak for climbing. The quality is tough and reliable to handle various professional tasks as per what you need. 10:1 for life support, 5:1 for rigging in most industries, but we seem to set our own in this industry. Dynamic ropes have a slew of other complex statistics in addition to breaking strength. Dynamic Load Management : The natural elasticity of polyamide allows these ropes to absorb sudden shocks and impacts, reducing the risk of sudden breaks under dynamic loads. In climbing your max sustained load is going to be approximately body weight, or maybe twice that if you have 2 people hanging from an anchor, say 400lb (2kN). For climbing ropes, the CE mark assures adherence to relevant EN standards. By following the MBS recommendation above, technical-use rope should be selected to meet or exceed the standard, depending on the likelihood of rescue KM III Static Rope is NFPA and CE certified, the KM III static line is perfect for rappelling, caving, top roping and life safety applications. Length: 100 ft. It is preferable to find rope that actually stretches Oct 9, 2023 · Static climbing ropes are characterized by their exceptional breaking strength.

Semi-static Rope: low stretch (1. See ‘breaking load’ below. Any knot tied in a rope creates a weak point. 7 (4 meter fall on 2. The same load represents 4% of the strength of a rope that has a 5,000 Lbs. Stretch Static rope (rope that stretches less than 6% while tensioned with 10% of its advertised breaking strength) is primarily used for caving. For example, 1/2" Dynasorb's has a tensile strength of 10,500 lbs, so 10% of that would be 1,050 lbs, which UIAA sanctions only the use of kernmantle rope for climbing. The breaking strength of the rope is 5,000 lb (22 kN) with elongation at 176 lb of 6. For instance, HMPE (High Modulus Polyethylene) boasts the highest breaking strength among synthetic fibers. This is standard arborist rope used for climbing and rigging. I know they are calling this a climbing rope with 5,900 lb breaking strength, but they are not tested by any regulatory agency or safety accrediting institution, specifically the UIAA! When ropes are tested for safety there is much more that is looked at than breaking strength. 5ft) at least 5 times without breaking and absorb enough force keep the system at or below 12kN. Knots reduce the breaking strength in half or something like that and a free fall of only 10 feet muliplys the weight on the rope something like 5 to 10 times, so I think that's why the WLL is so much lower then the actual breaking strength.
