Making an Impact on Sheet Piling

Although the classic Warrington-Vulcan and Super-Vulcan hammers were not the best suited to interface with sheeting, doing so was very common for these versatile hammers. Here are some examples broken down into two parts: the sheeting layouts and the cap configurations. These are from the years Vulcan was in Chicago, before it moved to Chattanooga … Continue reading Making an Impact on Sheet Piling

A Vulcan View of Hot-Rolled Sheet Piling

In the 1960's Vulcan put out its Data Manual, which is now (with some improvements) in the vulcanhammer.info Guide to Pile Driving Equipment. Part of that gave dimensions for a wide variety of sheet piling. The purpose of this post is to use some of these illustrations to show various types of hot rolled sheet piling … Continue reading A Vulcan View of Hot-Rolled Sheet Piling

Material on Vibratory and Impact-Vibration Equipment from the Soviet Union and Russia

Improvement of the Capacity of Vibrating Hammers for Driving Pipes Into Soils (article in English) M.G. Tseitlin, VNIIGSOsnovaniya, Fundamenty i Mekhanika Gruntov, No. 3, pp. 6-9, May-June, 1973 It is known that vibrating hammers (impact-vibration hammers) are highly effective for driving pipes. However, their wide use is prevented by their insufficient durability and high energy … Continue reading Material on Vibratory and Impact-Vibration Equipment from the Soviet Union and Russia

Articles and Monographs on Vibratory and Impact-Vibration Equipment Written by Vulcan Personnel

Development of a Parameter Selection Method for Vibratory Pile Driver Design with Hammer Suspension This paper details the mathematical modelling of vibratory pile driving systems using a linear model with the objective of obtaining a closed form solution to estimate either the power requirement of the machine, the torque requirement of the motor driving the … Continue reading Articles and Monographs on Vibratory and Impact-Vibration Equipment Written by Vulcan Personnel

Once Again, Driven Piles are First

From this article about the discovery of settlements 3,000 years old around Lake Lucerne in Switzerland: Experts used radiocarbon analysis to date the artifacts to about 1000 B.C., when the lake level was more than 16 feet lower than it is today, writes Garry Shaw for the Art Newspaper. According to the statement, these conditions … Continue reading Once Again, Driven Piles are First

Forty Years of “A Fistful of Yuan”

My trip report to the rest of Vulcan after I got back from this epic started with the following, forty years ago today: Out of the shadows came Jesse Perry (seated) and Lloyd Berwald. Jesse was Vulcan's most experienced field service person, who also had good customer relations skills along with an extensive knowledge of … Continue reading Forty Years of “A Fistful of Yuan”

If You’re Not Going to Use a Head Sheave, Use a Bar or Suspension Type Head

In Vulcan Onshore Tip 65, the safe use of sheave type cylinder heads is discussed. A view of the different types of sheave/sheave head/sheave pin/retaining pins from that tip are shown at the right. In the a more recent post, a more detailed diagram of a sheave head is shown below. Some Vulcan users feel … Continue reading If You’re Not Going to Use a Head Sheave, Use a Bar or Suspension Type Head

Reconstructing a Soviet-Era Plastic Model to Predict Vibratory Pile Driving Performance

The latest in our series of monographs on vibratory pile drivers, this one takes us back to the beginnings of vibratory pile driving in the Soviet Union. It was prepared for the ReSEARCH Dialogues at the University of Tennessee at Chattanooga in April 2021. The vibratory driver that started it all: the Soviet BT-5, used … Continue reading Reconstructing a Soviet-Era Plastic Model to Predict Vibratory Pile Driving Performance
