12/15/2023 0 Comments Karabiner seil![]() ![]() These are usually the heaviest carabiners.Ĭarabiners fall into three broad locking categories: non-locking, manual locking, and auto locking. The largest HMS carabiners can also be used for rappelling with a munter hitch (the size is needed to accommodate the hitch with two strands of rope). Used for belaying with a munter hitch, and with some types of belay device. Pear/HMS: Wider and rounder shape at the top than offset-D's, and typically larger.Offset-D: Variant of a D with a greater asymmetry, allowing for a wider gate opening.D: Asymmetric shape transfers the majority of the load on to the spine, the carabiner's strongest axis.Their greatest disadvantage is that a load is shared equally on both the strong solid spine and the weaker gated axis. Smooth regular curves are gentle on equipment and allow easy repositioning of loads. Types Shape Ĭarabiners come in four characteristic shapes: They are usually rated for a safe working load of 5 kN or more (equivalent to a weight in excess of approximately 500 kg). Load-bearing screw-gate carabiners are used to connect the diver's umbilical to the surface supplied diver's harness. While any metal link with a spring-loaded gate is technically a carabiner, the strict usage among the climbing community specifically refers only to devices manufactured and tested for load-bearing in safety-critical systems like rock and mountain climbing, typically rated to 20 kN or more.Ĭarabiners on hot-air balloons are used to connect the envelope to the basket and are rated at 2.5, 3, or 4 tonnes. Most are stamped with a "not for climbing" or similar warning due to a common lack of load-testing and safety standards in manufacturing. Often referred to as carabiner-style or as mini-carabiners, carabiner keyrings and other light-use clips of similar style and design have also become popular. Those used in sports tend to be of a lighter weight than those used in commercial applications and rope rescue. They are predominantly made from both steel and aluminium. The word is a shortened form of Karabinerhaken (or also short Karabiner), a German phrase for a "carbine rifle hook" used by a carbine rifleman, or carabinier, to attach his carbine to a belt or bandolier.Ĭarabiners are widely used in rope-intensive activities such as climbing, fall arrest systems, arboriculture, caving, sailing, hot-air ballooning, rope rescue, construction, industrial rope work, window cleaning, whitewater rescue, and acrobatics. Using a carabiner to connect to a ropeĪ carabiner or karabiner ( / ˌ k ær ə ˈ b iː n ər/), often shortened to biner or to crab, colloquially known as ( 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. ![]()
