Dragline Chain

Dragline Chain

From field studies we’ve noticed that most chain wear occurs at link contact areas. The solution: Columbia Steel’s integrally cast XtraLife™ chain with extra crutch material for extra long life.  It’s made from our H-alloys for excellent abrasion and impact resistance.  And for even longer life, try our Xtend Process™ high carbide overlay.
