The cast grapple link solution by Columbia Steel
Columbia Steel produces grapple links cast out of high strength alloy steel. These are manufactured as one piece, and are substantially stronger and less likely to fail during use than the standard fabricated links. Cast links are quickly proving to be a better wear solution than common fabricated grapple links.
Our product engineers worked closely with customers when designing our grapple links. The original fabricated part was overstressed and often saw premature breakage. Columbia Steel used solid modeling and finite element analysis (FEA) to redesign a new cast version.
Our grapple link is cast out of our own martensitic steel alloy for a combination of high strength and toughness.
Weld-on cast grapple points are also available.
