Chains are connected links or rings in various shapes and lengths, usually made of metal or plastic, that are used primarily for fastening items or pulling loads. They are also used for lifting, rigging, hoisting, binding, suspension, and motion-control applications. A combination of characteristics including material, finish, construction, diameter, length, and breaking strength give each chain its performance capability. Chain materials are selected for properties such as strength, elasticity, conductivity, and chemical- and weather-resistance. Chains can be fitted with accessories including clips, shackles, hooks, links, and swivels among others to prevent tangling, aid guiding, and allow clamping to other chains. Chains are most commonly used in the manufacturing, transportation, oil, mining, agricultural, and construction industries.
Campbell Chain manufactures chain, wire rope, and accessories for agricultural, construction, marine, manufacturing, and industrial applications. The company, founded in 1919, is headquartered in Sparks, MD.
