HEKO attachments are drop forged, tempered and chain contact surfaces are case hardened to minimise wear. They are employed for single and multi-strand applications for securing the scraper bar in the middle und thus provide additional strength and security. These attachments can run over pocket toothed wheels with single or twin strand conveyors and with special scraper bar designs also over wheels with projecting teeth. The two attachment halves each have two holes and a pair will be connected with the scraper bar by two bolts and nuts grade 8.8. or 12.9.
