Dragline Chain

2MT is proud to supply the world's leading dragline chain by Columbia Steel.



2MT Mining Products is the exclusive distributor of Columbia Steel dragline chain to the Australian coal mining market; the brand that has set the benchmark in the Australian coal mining industry for over 30 years. Columbia Steel is a proven winner and guaranteed to provide the most consistent results in the long run.

The manufacture of dragline chain is not easy: Columbia Steel has honed the skill of dragline chain manufacture through their 110 years of steel casting experience

Columbia Steel XtraLife® dragline chain is the industry standard. XtraLife® is the preferred dragline chain for mining companies relying on consistent performance and a long product life cycle. You won’t get the same consistency and endurance from any other dragline chain.

Features of the XtraLife® dragline chain are:
Integrally cast steel chain, giving superior link integrity due to an exclusive moulding process especially developed for the manufacture of dragline chain.

Utilising the proven Columbia steel proprietary H Alloys which consistently provides resilence, toughness and longer wear life.

Greater contact area – better distribution of stress and crutch wear

High strength and abrasion resistance



Xtend Process- High carbide overlay application
TIP: The Xtend Process overlay applied to high wear areas will increase chain rail wear life in more abrasive conditions.
Consult 2MT sales and product support representative for advice about this added feature.


TwistLink®chain - a unique design for superior performance


2MT and Columbia Steel product engineers are continually improving dragline components. The newest generation of the patented TwistLink hoist and drag chain is contoured for smooth operation and increased chain flexibility. It is cast from the same material as XtraLife® chain — the industry benchmark

Benefits:
Weight reduction of up to 22%
Increased surface area in bite region
Increased cross-sectional strength
Cost savings
Weld-in Repair links available


TwistLink can provide improvements in either the hoist or drag application. Its good resistance to abrasion and excellent ability to handle impact are the results of the H-series alloy's high tensile strength and toughness
