Dragline and Crusher Wear Parts Done Right.

Dragline Chain

For reliable dragline chain, it’s got to be XtraLife by Columbia Steel

Exclusive 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.

Greater contact area

Some conventional oval section chain links start with a virtual point contact area, which immediately begins to wear at this point of contact.

After studying wear patterns in the field we noticed that most chain wear takes place at the link contact areas. The solution: Columbia Steel’s integrally cast XtraLife chain with extra bearing area for extra long life. XtraLife chain’s additional ridge of metal is far greater than that of oval chains. Wearing stresses are distributed rather than concentrated. The result is longer link life and fewer premature stress failures.

XtraLife Dragline Chain from Columbia Steel

High strength and abrasion resistance

XtraLife chain 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.

A proven endurance winner

In tests in a major Western U.S. coal mine, our XtraLife chain moved 11.8 million cubic yards of overburden, compared to 7.5 MMCY for the previous chain. Other locations are having similar results with Columbia XtraLife chain.

Guaranteed

All Columbia Steel parts are guaranteed for proper fit, performance and customer satisfaction.
