Ketjunsiirroilla

Ketjunsiirroilla is a Finnish term used mainly in mechanical engineering and production contexts. It describes a method or system in which movement or transfer of parts, products, or materials is accomplished through chain-based mechanisms, such as conveyor chains, chain-driven transfer bars, or sprocket-driven indexing devices. The form ketjunsiirroilla is the adessive plural form of ketjunsiirto, literally meaning “on chain transfers” or “by chain transfers.” The term emphasizes the means of conveyance rather than the object being conveyed.

In practice, ketjunsiirroilla may appear in descriptions of assembly lines, packaging lines, or material-handling systems that use chains to carry items from station to station or to reposition them between processing steps. It is commonly found in maintenance manuals, system specifications, and technical reports where chain-driven transfers are a defining characteristic of the equipment.

Variations of the concept include chain conveyors, chain indexing, and chain transfers between linked machines. The exact interpretation can vary by manufacturer or field, and the term is not a standardized technical specification in all contexts.

See also: chain conveyor, sprocket, transfer mechanism, chain drive. References to ketjunsiirroilla appear in Finnish-language industrial literature and documentation describing chain-based material handling.
