A chain is a serial assembly of connected pieces, called links, typically made of metal, with an overall character similar to that of a rope in that it is flexible and curved in compression but linear , rigid, and load-bearing in tension . A chain may consist of two or more links. Chains can be classified by their design, which can be dictated by their use:
3-416: Two distinct chains can be connected using a quick link , carabiner , shackle , or clevis . The load can be transferred from a chain to another object by a chain stopper . Uses for chains include: Several methods are available to connect chain ends to each other or to other objects, and to apply a load to a chain away from the ends. These methods are usually specific to the type of chain, and must be of
6-577: A hyperlink . Maillon A maillon , maillon rapide or quick link is a metal link, similar to a carabiner . Maillons have a threaded sleeve which tightens over a thread, as opposed to a hinged gate like a carabiner, making them stronger, but more difficult to use. Like carabiners, maillons are available in a range of shapes and thicknesses (i.e., strengths), and often offer greater versatility over carabiners as their different shapes and lack of hinged gates allow them to be used in multi-directional load situations. The word maillon comes from
9-474: The correct size. The metal link chain has been in use since at least 225 BC. The prevalent modern symbolism is oppression , due to the use for a mechanical restriction of the liberty of a human or animal. Chains can also symbolize interconnectivity or interdependence .
