Section Modulus of Pile Hammer Leaders

In some manufacturers' literature, you'll see the "section modulus" of leaders as part of the specifications. (Ironically, Vulcan never put this in their specifications.) So what is this? How is it derived? And how is it useful? Are there any things we need to understand in using it? (The answer to the last is "of … Continue reading Section Modulus of Pile Hammer Leaders

Key Ball Cushion Ring

Vulcan always tried to be responsive to the needs of its customers. Sometimes, however, the way they wanted to do things got in the way of progress, and the Key Ball Cushion Ring was a good example of that in action.

Stresses for Curved Beams with Rectangular Cross Sections

In the early 1960's Vulcan became involved with the Sand Drain hammers. Part of that effort was developing a servo-pneumatic hook block to grab and lift the hammer and everything else what was attached to it. The device is shown above. Vulcan received a patent for it. Here we'll concentrate on one aspect: the design … Continue reading Stresses for Curved Beams with Rectangular Cross Sections

Maintenance Manual for Super-Vulcan Hammers

Getting the Point: Vulcan and Pile Shoes

In some ways Vulcan came into the pile hammer business as a "one-stop shop." One of those stops was pile points. The first drawing produced of these was in 1896; the first documented appearance of these accessories in the catalogue was in 1909. As the drawings below show, evidence of them persists until the 1950's. … Continue reading Getting the Point: Vulcan and Pile Shoes
