Vulcan's personnel brought back many colourful stories from the field. One of those came from Jesse Perry, Vulcan's senior field service representative. Offshore pile driving is a brutal, unforgiving business; offshore piles are tip elevation piles, and the expediency of "beating the pile to death" to get done in the high hourly barge rates was … Continue reading Vulcan 040 and 340 Hammers: Specifications and Information

The Stamp of Quality…Everywhere
Vulcan frequently produced an ad for the Offshore Technology Conference. Probably the best one was the "Stamp Ad." The "stamp of quality" theme had appeared in Vulcan's literature for many years before that, but Vulcan's graphic artist Carol Carr took it to a new level with this one in the early 1970's. It was unusual … Continue reading The Stamp of Quality…Everywhere
Compressible Flow Through Nozzles, and the Vulcan 06 Valve
Most of our fluid mechanics offerings are on our companion site, Chet Aero Marine. This topic, and the way we plan to treat it, is so intertwined with the history of Vulcan's product line that we're posting it here. Hopefully it will be useful in understanding both. It's a offshoot of Vulcan's valve loss study … Continue reading Compressible Flow Through Nozzles, and the Vulcan 06 Valve
The Valve Loss Study
All fluid flow in Vulcan hammers is regulated and directed by a valve. For most Vulcan hammers (the California series being a notable exception, the #5 is another) the valve is a Corliss type valve modified from those used in steam engines. Simple and reliable, it, like any other valve, is subject to losses as … Continue reading The Valve Loss Study
General Arrangements and Assemblies
One of the typical information items Vulcan would send out would be the "general arrangement" (or assembly, to use the Raymond terminology) of a hammer, or a sub-assembly such as a capblock follower. These were also included in the offshore field service manuals. Sometimes they would feature the specifications of the hammer. They are useful … Continue reading General Arrangements and Assemblies
Decelflo Pile Hammer Muffer, and the Thruflo Muffler
One thing most people notice first about pile driving jobs is that they generate an elevated level of noise. Until the 1960's, most people simply put up with this and many other aspects of industrialisation and development. In the early 1970's, Vulcan and other pile driving equipment manufacturers were confronted with new regulations--both at the … Continue reading Decelflo Pile Hammer Muffer, and the Thruflo Muffler
Vulcan Hammer Noise Study
Note: This study was commissioned by Vulcan and conducted in early December 1972 by United Acoustical Consultants of Glastonbury, CT, and dated 23rd June 1973. The report was submitted by the President of UAC, Mr. Stannard M. Potter. It has been released publicly by Vulcan at various times since its completion. This is the text … Continue reading Vulcan Hammer Noise Study
Vulcan and Hammer Leaders
Leaders is the generic term for the guide which allows the pile hammer to be positioned on top of the pile and then started to drive the pile to its desired head elevation. Although not a prominent part of Vulcan product line, the company did produce leaders of many kinds. This page is also intended … Continue reading Vulcan and Hammer Leaders
Vulcan Expanding Mandrel, and Mandrel Driven Shell Piles
From a corporate standpoint, the Vulcan Expanding Mandrel (right) was one of its more forgettable products. But the application of mandrel-driven shell piles is an important one in deep foundations, as it represents, from a design standpoint, an interesting combination of driven and drilled piles. Pile Shells and Mandrels Driven piles can be divided into … Continue reading Vulcan Expanding Mandrel, and Mandrel Driven Shell Piles
Vulcanaire Supertherm, and the Airmizer Hammers
Energy conservation is an important consideration today in a world where the competition for energy sources is intensified by rising demand. But making best use of fuel isn't new, and both the Vulcanaire Supertherm and the Airmizer hammers were Vulcan's contribution to energy savings. Both of these products were the original idea of Moses Hornstein, … Continue reading Vulcanaire Supertherm, and the Airmizer Hammers
