Vulcan Pile Hammers: Adaptability, Portability, Flexibility, Sensibility and the Ability to Get the Job Done on Time

We've featured ads that Vulcan put in Engineering News-Record, but this one was a flyer that Vulcan put out about a successful application of a Vulcan #2 in Memphis, Tennessee. The hammer was run using a Littleford Tank Heater to generate the steam. Vulcan flyer for a #2 driving piles in Memphis, Tennessee, in the … Continue reading Vulcan Pile Hammers: Adaptability, Portability, Flexibility, Sensibility and the Ability to Get the Job Done on Time

The Smelliest Cigars of Them All

In many ways, the world we live in is a different place from when Vulcan went offshore fifty to sixty years ago. Some of the issues remain, such as energy independence and security. But others, in the U.S. at least, have been banished from the public square. One of those issues is smoking. I duly … Continue reading The Smelliest Cigars of Them All

Tribute to Sylvia Williams

It's belated, but I didn't get the word about this until another Vulcan employee let me know. Sylvia Williams, Vulcan's office manager and confidant to its Chairman and Chief Executive Officer, Mrs. Vernell S. Warrington, passed away 11 February 2022. From her obituary: It is with great sadness that we announce the death of Sylvia … Continue reading Tribute to Sylvia Williams

This is the Warrington-Vulcan Pile Hammer

Another ad for Vulcan in Engineering News-Record, this in the 5 July 1928 issue. Vulcan touted the "heavy ram/low striking velocity" feature here, had done so in the past, and would do so again for many years. Specifications for these hammers can be found here. Other ads from the same era: Driving Speed That Makes … Continue reading This is the Warrington-Vulcan Pile Hammer

Stonedril Water Well Drills

In the summer of 1966 Vulcan acquired the assets of the Stone Drilling Machine Company of Daisy, TN, north of Chattanooga. The principal had passed away. The product was a water well drill which stone had manufactured for many years. It was another attempt on Vulcan's part to diversify its product line; even with the … Continue reading Stonedril Water Well Drills

Section Modulus of Pile Hammer Leaders

In some manufacturers' literature, you'll see the "section modulus" of leaders as part of the specifications. (Ironically, Vulcan never put this in their specifications.) So what is this? How is it derived? And how is it useful? Are there any things we need to understand in using it? (The answer to the last is "of … Continue reading Section Modulus of Pile Hammer Leaders

Key Ball Cushion Ring

Vulcan always tried to be responsive to the needs of its customers. Sometimes, however, the way they wanted to do things got in the way of progress, and the Key Ball Cushion Ring was a good example of that in action. Vulcan had used the "standard pot" to hold its cushion material from the beginning … Continue reading Key Ball Cushion Ring

Stresses for Curved Beams with Rectangular Cross Sections

In the early 1960's Vulcan became involved with the Sand Drain hammers. Part of that effort was developing a servo-pneumatic hook block to grab and lift the hammer and everything else what was attached to it. The device is shown above. Vulcan received a patent for it. Here we'll concentrate on one aspect: the design … Continue reading Stresses for Curved Beams with Rectangular Cross Sections

A Diesel Hammer that “Looks Like a Vulcan?”

It's interesting how many impact pile hammers are designed to "look like a Vulcan." Obviously there are those like Conmaco and Raymond that were "offshoots" of the successful Warrington-Vulcan and Super-Vulcan hammers. All of these hammers are or were air-steam operated hammers. Others have used the ram/column arrangement to develop hydraulic impact hammers, with varying … Continue reading A Diesel Hammer that “Looks Like a Vulcan?”
