When WEAP86/87 was introduced, one of the major advances was the inclusion of a comprehensive hammer database. This has been continued and expanded in subsequent versions such as GRLWEAP 2003 and GRLWEAP 2010. One anomaly was that, although the Vulcan #2 and Vulcan 30C hammers were included in the database, the driving accessory information was … Continue reading GRLWEAP Accessory Specifications for the Vulcan #2 and 30C Hammers
It is my custom to link to and make comments on papers which cite my work. This paper is titled Construction of a mathematical model of dynamic loads in a jib self-propelled crane when pulling a sheet pile out of the ground. It comes from Ukraine, and it is the first study of its kind … Continue reading Comments on “Construction of a mathematical model of dynamic loads in a jib self-propelled crane when pulling a sheet pile out of the ground.”
When Vulcan introduced the Vari-Cycle in the late 1960's, it thought that the issue of stroke changing during operation had been solved. But there were exceptions Both the #1 and #0 series hammers had difficulties with physically accommodating the Vari-Cycle, and when the 5' stroke hammers were introduced in these size ranges there were durability … Continue reading Traverse Trip
The manual for this program (which can be found here) is back in print. The book is also a valuable reference for the basic theory behind the wave equation for piles. You can order the book by clicking here or on the cover image at the right. A detailed description of the book follows: WEAP86/WEAP87 … Continue reading WEAP86: Wave Equation Analysis of Pile Foundations Back in Print
It is with great regret that the discontinuation of our "active pages" is announced. By "active pages" we mean the software that was designed for use in a web browser. With the migration of the "vulcanhammer" family of sites it is not possible to host these here, and changes in the hosting service have made … Continue reading The Discontinuation of Our Active Pages, and the Substitutes
Click here to view the home page for the book. The theory of vibrational and impact-vibrational immersion is connected with the study of essentially non-linear systems, in which the nonlinearity is determined both by the forces of resistance (for example, when studying longitudinal-rotational vibrations) and by the dynamics of the vibration exciter itself, for example, … Continue reading Basics Of The Theory Of Vibratory Immersion and Extraction
The development of excavator mast technology has broadened the application of pile driving equipment. Below is another way of mounting pile driving equipment, in this case using a heavy duty forklift. https://youtube.com/shorts/BnbMkty7ZBc?feature=share MKT 10B3 operating on a Manitou MHT 10210 forklift with leaders, headblock and fork mounts put together by Vulcan Foundation Equipment, Ft. Payne, … Continue reading Mounting Pile Hammer Leaders on a Forklift
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
There's finally some meaningful pushback against this: But significant amounts of that waste could be avoided through repairs. According to a study by the French Environment and Energy Management Agency, only 40% of electronics breakdowns in France are repaired. But surveys have found nearly two-thirds of Europeans would rather repair their products than buy new … Continue reading Vulcan Never Believed in a “Throwaway Culture”
Driving piles wild, i.e., without any leader of any kind, is something that takes a great deal of skill and forethought by the contractor. Like piles driven with a stub leader, it is necessary at least to use some kind of template to insure that the pile is on location and in alignment, and also … Continue reading Driving Concrete Piles Wild
