Vulcan 030 and 330 Hammer: Specifications and Information

The Vulcan 030 was an extension of the 020 with a longer, heavier ram.  It was first designed and built in an onshore version with the same 37″ jaws as the 020.  A general arrangement is below.

The onshore 030 found itself on many interesting projects, such as the replacement of the Sunshine Skyway Bridge between St. Petersburg and Bradenton, FL, after it was hit by a ship and fell into Tampa Bay.

Like the 020, the 030 went offshore, too.  The first offshore 030 was built for H.B. Fowler in 1965; a general arrangement is shown below.

The original offshore Vulcan 030, built for H.B. Fowler in 1965 and J.H. Pomeroy in 1967.  Note the column keys that hold the hammer together; they were replaced by cables, as keys were hard to maintain in the punishing offshore environment.

Equipped with cables and (after the first three) a 22″ ram point (the first three had a 21″ one,) the offshore 030 was used by contractors such as Northwestern, Dragados and Fluor.

Specifications for the offshore 030 are below.

In its later specification sheets Vulcan listed a Vulcan 330 hammer, but it is essentially the same as the 030, and was not built.  General arrangements and specifications are below.
