Link chains for mining industry
We offer mining link chains manufactured according to DIN 22252 and PN-G-46701 norms in class B and C, as well as link chains with improved mechanical and resistance properties (class PW9 and D)
All chains have been tested and approved for use in the mining industry. Class C chains are popularily used in shorter conveyors. PW9 class link chains are recommended everywhere, where increased resistance to breaking is needed. It is not suggested to use PW9 in corrosively aggressive environments.
Technical parameters mining link chains manufactured according to PN-G-46701:1997, DIN 22252-2002 - cl.2 and DIN 22252-2001 - cl.1
