Sammenkæde

Sammenkæde is a Danish noun meaning a chain, a series of linked elements, or a mechanism joining items in sequence. In common usage it refers to a physical chain of metal links used to transmit movement, suspend loads, or secure objects. As a verb, sammenkæde also means to chain together or to form a sequence.

A chain consists of individual links connected to form a flexible but strong line. Chains are usually made of steel, including carbon steel and alloy steels, sometimes stainless steel for corrosion resistance; other materials such as nylon are used for light-duty, non-load-bearing chains. Links are formed by casting, forging, or stamping and are joined by riveting, welding, or pin connections. Chains are classified by strength ratings (grades) and by design (roller chains for power transmission, link chains for lifting or securing).

Applications of chains include machinery power transmission (chain drives), lifting and rigging, conveyance and material handling, agriculture, mining, and safety equipment. In architectural or decorative contexts, chains are used as trims or anchors. Safety considerations include proper load rating, corrosion protection, maintenance, and regular inspection for wear or elongation; damaged chains should be replaced. Standards such as ISO, DIN, and EN govern dimensions and strength ratings.

Sammenkæde conveys the idea of linking elements into a unified sequence, reflecting both structural and functional aspects of chains in engineering and everyday use.
