Ketjukuljetteja

Ketjukuljetteja is a Finnish term used in industrial engineering contexts to describe a chain-driven transport mechanism that moves goods along a production or handling line. The concept refers to a conveyor system consisting of linked chain segments that act as carriers or support structures for items. The name derives from ketju (chain) and kuljettaa (to transport), with the suffix -ja indicating an agent; the plural ketjukuljetteja denotes several such modules or units.

Design and operation: The system comprises modular chain sections that can be arranged in straight or curved paths. Each section contains a chain driven by motors, with carriers or pallets riding on the chain surface or in pockets. The modules synchronize via drives and sensors; speed, tension, and spacing can be adjusted. The chain surface often provides low-friction contact for heavy or bulky loads, and the modular nature allows reconfiguration to suit changing requirements.

Applications: Ketjukuljetteja is applied in manufacturing lines, warehousing, and material handling where durable, low-maintenance transport is required, especially for heavy goods, irregularly shaped items, or environments where belt conveyors would face wear or contamination issues.

Variants and comparison: Compared with belt conveyors, ketjukuljetteja systems can offer higher weight capacity and robustness but may require more maintenance due to chain wear. In contrast to roller conveyors, they provide continuous support along the path and can be more suitable for items that need stable support over the transport distance.

Notes: The term is used in Finnish-language sources to describe a class of chain-based transport modules; in practice, it is often discussed alongside general chain or modular conveyor systems without always constituting a distinct technology.
