Forged flight bars are used with round link & flat link chain assembly for conveying coal and other mining goods in particular. Materials are of high cr & mo alloy steel, offering sound toughness and wearing life.

Flight bar types can be classified as below, from its popularity:

Inboard flight bar

Outboard flight bar

Twin chain flight bar

Triple chain flight bar

Single chain flight bar

Application

Armored Face Conveyors (AFC),Beam Stage Loaders (BSL)

Typical flight bars can be made to Chinese MT/T 323 standards or DIN 22259, which are widely used in face conveyors and beam stage loaders. Clamps (with quality bolts & nuts) fitness with flight bars has well taken into consideration the dimensional fitness, easy assembly and required mechanical properties.

More types flight bars and scraper bars to clients specifications / designs can be supplied.
