Tensioners on Alcoa 50,000-ton press

Superbolt tensioners on Alcoa 50,000 ton press

When Alcoa decided to redesign and rebuild their iconic 50,000 ton press located in Cleveland, OH they contacted Superbolt to design specialty tensioners that could handle the demanding bolting requirements. Superbolt supplied (8) 40″ tensioners, (8) 39″ tensioners, (8) 39″ split nuts, (4) 11″ tensioners, and (4) 11″flexnuts.

Hundreds of various multi-jackbolt tensioners are also used on the press auxiliary equipment, such as pumps, valves, piping, etc. This monumental project was completed successfully, resulting in Alcoa’s largest forging press in North America.

See the video on Alcoa’s new press below. You can see the massive Superbolt multi-jackbolt tensioners at the top of the press:
