Link chains for scraping conveyor systems
Scraping conveyor systems use mining chains manufactured in accordance to the DIN 22252, PN-G-46701 norms as well as increased mechanical and resistance grade chain (PW9, D)
All chains have been tested and have been approved for use in the mining sector. Grade C chains are commonly used in shorter conveyor systems. PW9 and D grade chains are suggested everywhere, where increased durability and tear resistance is needed.
Technical parameters of mining link chains according to PN-G-46701:1997, DIN 22252-2002 - grade 2 and DIN 22252-2001 - grade 1 norms.
