Wear Parts for Industry

Hoist & Drag Chain

XtraLife dragline chain: the industry standard worldwide.

Columbia Steel dragline hoist and drag chain - the industry standard.

A proven endurance winner over the long haul
Some conventional oval section chain links start with a virtual point contact area, which immediately begins to wear during use. XtraLife® chain’s additional ridge of metal is far greater than that of oval chains. Wear stresses are distributed instead of concentrated. The result is longer link life and fewer premature stress failures.

XtraLife chain, cast in our H-alloys, has good resistance to both abrasion and impact. For greater resistance to abrasive wear, our Xtend Process® high carbide overlay can be bonded to high wear areas, resulting in even longer life.

Exclusive Columbia casting system
Columbia Steel has developed a special molding line which ensures superior link integrity throughout the chain strand. The resulting integrally cast chain has become known as the world’s leading dragline chain.
