Dragline Chain from Columbia Steel

タイトルまたは説明

XtraLife® Dragline Chain: The Industry Standard. After studying wear patterns in the field Columbia Steel noticed that most dragline 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. Greater contact area. Some conventional oval section dragline chain links start with a virtual point contact area, which immediately begins to wear at this point of contact. XtraLife dragline 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. High strength and abrasion resistance. XtraLife dragline chain, utilizing 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. High strength and abrasion resistance.

Ask about our new TwistLink® dragline chain *- it can save up to *8% in weight compared to XtraLife chain, while supplying the same strength.
