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
One of the mysteries of geotechnical engineering relative to driven piles is why the Soviets, with their mathematical prowess, never applied wave mechanics to predict the performance of pile driving systems using the wave equation. In a sense this book, which is a classic in the geotechnical literature, answers that, but not in a direct … Continue reading Some Lessons from “Savinov and Luskin”
