E-Bolt is a major part of the scraper conveyor, which is an important component of a fixed chain and scraper, both mechanical parts, they are wearing parts, need to have a good overall performance, E-Bolt is a class branches and symbiotic piece fork class is rare in forgings, forgings and thus introduce it makes sense. Therefore, in order to forge a blade and chain bolt connections are most appropriate. E-Bolt is a symbiotic pieces classes and fork like branches, is rare in forgings, forgings and thus introduce it makes sense.
