The 65C is the counterpart to the Warrington-Vulcan 06 hammer. Upsizing single-acting hammers is a fairly straightforward process as long as the frame is capable of withstanding the load. Doing the same thing with differential-acting hammers such as the 50C is an entirely different matter, as the 65C shows. Specifications are on the general arrangement … Continue reading Vulcan 65C and 65CA Hammers: Specifications and Information
Like its Warrington-Vulcan counterpart, the #1, the 50C was a popular hammer and, along with the 80C, comprised a large block of Vulcan's production of these hammers. Specifications are below.

The general arrangements are interesting not just for the 30C but to explain features and variants in the Vulcan product line. Like parent, … Continue reading Vulcan 30C Hammer: Specifications and Information
The 18C is the smallest of the Super-Vulcan hammers, designed to correspond with the Warrington-Vulcan #3. Specifications for the hammer are below.

One interesting footnote to its history is that the 18C was the … Continue reading Vulcan 18C Hammer: Specifications and Information
The #4, another one of the early Warrington-Vulcan hammers, was the smallest one designed and produced. It was referred to as the "Fish Stake" hammer, because, as Vulcan's literature explained, it was "used for driving fish stakes for pond nets along the shore and in connection with sheeting cap, for small wooden sheeting." Specifications for … Continue reading Vulcan #4 Hammer: Specifications and Information
One of the more interesting products that Vulcan spent a great deal of time on but was not able to actively pursue was the concrete pile cutter. The technology for the cutter was developed by two Soviet institutes: VNIIstroidormash in Moscow and Dalniis in Vladivostok. How Vulcan obtained the rights to the patent was an … Continue reading Concrete Pile Cutter SP-88 Operations Manual
Background The Foster hammers are an interesting part of Vulcan's last years. The concept was to produce a vibratory hammer under a "private label" arrangement, a novelty for the pile driving equipment industry at the time (although the "Chimag" diesel hammers were a similar concept.) In the early 1990's Vulcan produced several vibratory hammers for … Continue reading Hydraulic Vibratory Hammer: the Foster 4200

In his assessment of the prospects of US-China relations, former Australian Prime Minister Kevin Rudd makes the following suggestion to resolve intellectual property (IP) issues: Intellectual-property protection, however, is deeply problematic. Previous agreements reached under US president Barack Obama’s administration could be reconstituted. But the jurisdictional enforcement of breaches is still hopeless. One possible mechanism … Continue reading An Old Idea Comes Back: China-US Arbitration in a Neutral Country
