When God Threw His Wallet on the Table

One of the many "characters" in Vulcan's long (144 year) history was Jesse H. Perry, Vulcan's senior field service representative right up until his sudden death.  As I mention elsewhere, it took a very special kind of person to do what Jess did.  Construction is a high risk activity, and that's especially true with offshore … Continue reading When God Threw His Wallet on the Table

Vulcan Offshore Hammer Clearance Dimensions

In an earlier post we presented the clearance dimensions for Vulcan onshore hammers.  Above are those for the offshore hammers as well.

How Vulcan Extractors Work

Vulcan was generally not hesitant to include information on the cycle workings of its air/steam hammers, but for some reason never included similar information on its extractors.  Above is a diagram from 1940 which shows how this is done. Basically we start with the view on the left.  Air or steam is admitted through inlet … Continue reading How Vulcan Extractors Work

Onshore Hammer Clearance Dimensions

Above is a clearance chart from 1979 of Vulcan's onshore air/steam hammers.  The clearance chart is helpful in that it can show whether your Vulcan hammer can fit into a given set of leaders. One thing to keep in mind is that, if your leaders have a low distance from the front to the back … Continue reading Onshore Hammer Clearance Dimensions

Slide Bar Gripper

Once Vulcan got past designs such as this, the slide bar (the cam which turned the valve during operation) was retained in a ram using a key driven though the base of the slide bar.  The slide bar interfaced with the ram using a spherical block to allow rotation of the bar, necessary to compensate … Continue reading Slide Bar Gripper

Vulcan 5110: Specifications and Information

The 5110 was the last new model that Vulcan "produced" and was the first beneficiary of Vulcan's acquisition of Raymond technology in the early 1990's.  The one and only 5110 came into being by a conversion of a 560 owned by Global Movible Offshore.  This resulted in a hammer that was considerably lighter than the … Continue reading Vulcan 5110: Specifications and Information

Vulcan 5100: Specifications and Information

With the success of the 560 the 5' stroke concept was taken upward with the 5100, an extension of the 3100.  In addition to the longer stroke, it was Vulcan's first hammers with 120" jaws, to accommodate 96" piling.  The first 5100 was sold to Brown & Root (Western Hemisphere Marine, to be formal about … Continue reading Vulcan 5100: Specifications and Information

Vulcan 560 Hammer: Specifications and Information

The Vulcan 560 hammer became the "#1 of Vulcan offshore hammers," and the most popular of its offshore hammers from the 1970's onward.  Yet, although today the logic of a 5' stroke hammer (especially when compared to the diesel hammers) is obvious, at the time it took a little persuading. Vulcan had adhered to the … Continue reading Vulcan 560 Hammer: Specifications and Information
