Tensioners på Alcoas 50.000 tons store presse

Da Alcoa besluttede sig for at ændre og ombygge deres ikoniske 50.000 tons store presse i Cleveland, Ohio, kontaktede de Superbolt for at få konstrueret specielle tensioners, der kunne opfylde virksomhedens høje krav til sammenboltning. Superbolt leverede (8) 40" tensioners, (8) 39" tensioners, (8) 39" dobbeltmøtrikker, (4) 11" tensioners og (4) 11" flexnuts.

Der blev også brugt hundredvis af forskellige multi-jackbolt tensioners (MJT'er) på pressehjælpeudstyret såsom pumper, ventiler, rør osv. Dette kæmpe projekt lykkedes til fulde og resulterede i Alcoas største smedepresse i Nordamerika.
