Although Vulcan never placed it into production, the Single-Compound hammer was one of Vulcan's more interesting experimental hammers, and under different market circumstances has the potential of success. Although a general long-term success, Vulcan always recognised that the product life of the air/steam hammer line wasn't infinite, especially offshore. Given the difficulties of developing an … Continue reading Single-Compound Hammer
For the first three decades of the twentieth century, Vulcan issued a "general" product bulletin which featured all of its products in product. (Some material from those bulletins is here.) In a pre-internet age, printed bulletins were about the only way a company could advertise its products and provide its customers (current and prospective) information … Continue reading Vulcan Product Bulletins
Virtually all vibratory pile drivers use rotating weights to produce the alternating force that mobilises and fluidises the soil. But it's necessary to use the weights in pairs to cancel out the horizontal forces that result. What if the force could be produced using a reciprocating weight, thus eliminating the horizontal cancellation requirement? In the … Continue reading Reciprocating Vibratory and Impact-Vibration Hammers
By World War II, Vulcan's air/steam hammer line dominated its production and revenue stream. Of all of the attempts Vulcan made to diversify is pile hammer line after that time, probably the most successful was its line of vibratory pile hammers. Vibratory pile driving equipment represented a major departure for Vulcan, but it also represents … Continue reading Vulcan Vibratory Hammers and Vibratory Technology
The mid-1980's were lean years at Vulcan. The offshore market was still down, the aftermath of the collapse of oil prices earlier in the decade. Vulcan's own diesel program had to be stopped, plagued by design and manufacturing problems and an overvalued US Dollar. The vibratory hammer program was going reasonably well but the market … Continue reading Vulcan High-Frequency Vibratory Hammers
In 1984 Vulcan re-entered the vibratory hammer market with the introduction of the 1150 vibratory hammer. This hammer made its debut on a project in Bangor, Maine for Cianbro Construction. More suited for the American market and adequately powered, these machines were far more successful than the Vulcor hammers had been. The technology used was … Continue reading Vulcan’s Medium Frequency Vibratory Hammers
Vulcan's first venture into the vibratory market took place in the 1960's with the introduction of the Uraga electric vibratory hammer from Japan, which Vulcan marketed as the Vulcor Vibratory Hammer. Vibratory pile driving technology had been developed in the Soviet Union. One of the first countries to pick up the technology was Japan. With … Continue reading Uraga/Vulcor Vibratory Hammer
One of the more interesting applications of vibratory hammers is the installation of wick drains, a type of vertical drain. But vertical drains are of interest far beyond vibratory technology. Overview Soils are a composite of solid soil particles, water and air. When soils reside below the water table (phreatic surface,) there is no air, … Continue reading Vertical Drains: Sand and Wick
Vulcan was involved in a great deal of research on vibratory technology. Some of that effort was continued after Vulcan's passing by its personnel. It can be broken down into three parts, click on the topic you're interested in: Articles and Monographs on Vibratory and Impact-Vibration Equipment Written by Vulcan Personnel Material on Vibratory and … Continue reading Vibratory and Impact-Vibration Hammer Technology
