This is the Warrington-Vulcan Pile Hammer

Another ad for Vulcan in Engineering News-Record, this in the 5 July 1928 issue. Vulcan touted the "heavy ram/low striking velocity" feature here, had done so in the past, and would do so again for many years. Specifications for these hammers can be found here. Other ads from the same era: Driving Speed That Makes … Continue reading This is the Warrington-Vulcan Pile Hammer

Stonedril Water Well Drills

In the summer of 1966 Vulcan acquired the assets of the Stone Drilling Machine Company of Daisy, TN, north of Chattanooga. The principal had passed away. The product was a water well drill which stone had manufactured for many years. It was another attempt on Vulcan's part to diversify its product line; even with the … Continue reading Stonedril Water Well Drills

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. Vulcan had used the "standard pot" to hold its cushion material from the beginning … Continue reading Key Ball Cushion Ring

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

Minimum Bend Radius for Plate Bending

Although Vulcan was best known for products based on sand castings, many of Vulcan products--especially those produced by the Special Products Division--were fabricated. An important operation in fabrication is plate bending. Although plate bending is usually associated with sheet metal formation like Vulcan's vibratory power packs, Vulcan also bent plate which is thicker than normal … Continue reading Minimum Bend Radius for Plate Bending

Maintenance Manual for Super-Vulcan Hammers

The Super-Vulcan hammers were a step forward for Vulcan, albeit not as much as Vulcan was hoping for. Nevertheless they were a popular hammer for many years, especially once Vulcan went to the open type construction like the Warrington-Vulcan single-acting hammers. Here we feature a maintenance manual for these hammers. The manual is undated (an … Continue reading Maintenance Manual for Super-Vulcan Hammers
