Carabiner
Carabiners come in four characteristic shapes:
Oval: Symmetric. Most basic and utilitarian. Carabiners have smooth regular curves on equipment and it allows easy repositioning of loads. It has disadvantages, it is a load is shared equally on both the strong solid spine and the weaker gated axis.
D: The carabiner's strongest axis is its spine. Asymmetric shape transfers the majority of the load onto there. Offset-D: Offset D is a variant of a D. It has a greater asymmetry, that allows for a wider gate opening.
Pear/HMS: Wider and rounded shape at the top than offset-D's, and typically larger. Used for belaying with a munter hitch, and with some types of the belay device. HMS carabiners are the largest carabiner, that can also be used for rappelling. It can be used with a munter hitch (the size is needed to accommodate the hitch with two strands of rope). These are usually the heaviest carabiners.
Locking mechanisms
Locking mechanisms for carabiners can be classified as 3 categories: auto-locking, manual locking, and non-locking.
Carabiners are a part of the rope access equipment system. It is widely using in activities that required high skills and safety. For all the works, safety is an important factor. Especially the works at height. That requires more skilled workers and equipment to make sure the worker is safe.
For this purpose, the rope access equipment system has been developed. Rope access makes all the difficult to reach locations and points accessible in a safe and efficient manner. It refers to a set of techniques and specialized hardware equipment for working at heights.
Rope access equipment kit will contain all the basic equipment required for these works. Such as Carabiner, lanyards, harness, ropes, backup devices, ascender, descender...ect. It is available with different brand names. However, instead of brands, choose high-quality products for your safety.
