Welcome to John King Chains

The John King Company was established in Leeds, England in 1926. Early success was achieved in the manufacture of mechanical handling equipment for the rapid mechanisation of the coal industry. In these early days conveyor chain was generally of cast link construction. The Company therefore has unrivalled experience in the production of highest quality cast link chains in ductile irons and steel under the “Climax Quality Brand”. JOHN KING are undoubtedly the world leaders in this range of conveying chains.
