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.
Although cast link chains remain an important part of the JOHN KING programme, the company has progressively expanded the product range to encompass chains of other constructions and manufacturing techniques including Welded steel chains, Engineered steel chains, forged fork link chains and Engineering plastic chains. Today JOHN KING offer the widest range of conveyor chains of any manufacturer this makes them unique in being able to offer an infinite number of chain types in a variety of materials and constructions for a multiplicity of industrial mechanical handling applications.All products are manufactured within the dictates of the Company’s quality management according to ISO 9000 establishing consistent and high quality products and ensuring performance reliability and extended service life.
In recent years it has been JOHN KING’s strategy to develop the Company into a global business. This has seen the establishment, in addition to the United Kingdom, of a chain production plant in the US. John King USA Inc from their plant in East Peoria (IL) are well equipped with the manufacturing equipment for component production and assembly processes for high quality chain production serving North and South America. To provide best service in export markets the company have warehousing and distribution worldwide and maintain ambition plans to expand the network further in the future.
A key part of the development of the business in recent years has been the examination of process requirements within the business and the implementation of best techniques in production.
Round part production is with bar feed five axis machining centres and link plates by conventional and laser profiling technology with laser machines that include tower servers that will automatically deliver plate for processing and return cut parts to storage allowing the concept of “lights out” production to become a reality.
As part of the Company’s on going investment they have invested in a 100 Ton pull testing machine. This will not only allow for proof testing and destructive testing, but also calibrate chains as matched strands where they are to be utilised in twin strand operation.
John King operate in house sprocket production up to 3 metres in diameter. Profiles are designed to suit the application, for example a roller conveyor chain employed in an escalator will demand different design considerations to a drive sprocket in a Cement Clinker positive discharge elevator.
Sprockets are available in cast and fabricated styles with split, segmental or solid construction. Where appropriate tooth forms can be hardened.
Our technicians who have long experience in design and application of our product combined with intimate knowledge of the metallurgical considerations of chain production are available to support our customer’s in the design, selection and improvement of their chain conveying equipment.
The JOHN KING name is synonymous with the British tradition of courtesy, quality, service and good value in mechanical handling equipment.
