Vulcan 5110: Specifications and Information

The 5110 was the last new model that Vulcan "produced" and was the first beneficiary of Vulcan's acquisition of Raymond technology in the early 1990's.  The one and only 5110 came into being by a conversion of a 560 owned by Global Movible Offshore.  This resulted in a hammer that was considerably lighter than the … Continue reading Vulcan 5110: Specifications and Information

Vulcan 560 Hammer: Specifications and Information

The Vulcan 560 hammer became the "#1 of Vulcan offshore hammers," and the most popular of its offshore hammers from the 1970's onward.  Yet, although today the logic of a 5' stroke hammer (especially when compared to the diesel hammers) is obvious, at the time it took a little persuading. Vulcan had adhered to the … Continue reading Vulcan 560 Hammer: Specifications and Information

Vulcan 520, 530 and 535 Hammers: Specifications and Information

This series of hammers, an outgrowth of the 020 and 030 hammers, had a complicated history, as its development alternated between onshore and offshore configurations and applications.  Because of this they have proven versatile hammers applicable in both fields.

Knockout Rings, Large and Small

Above is a chart from 1965 of knockout rings for Vulcan hammers from the #2 to the 020/200C series.  The knockout ring is, in some way, a short version of the capblock follower/shield for softer cushion materials.  It replaces the integral ring which has  been standard on Vulcan hammers.  (Some explanation of both is here.)  … Continue reading Knockout Rings, Large and Small

Vulcan’s Blow Count Specifications

The durability and longevity of Vulcan pile hammer is something that is seldom replicated in just about any other manufactured product.  Since pile driving is self-destructive on the equipment, this is a remarkable achievement, but it should be tempered by the fact that it's possible to render a Vulcan hammer inoperable by the way it's … Continue reading Vulcan’s Blow Count Specifications

Driving Piles with Stub Leaders and a Template

The best known setup for pile driving equipment is a crane and a set of full-length (of the pile and hammer) leaders, attached to the crane in a variety of ways.  But another alternative is to use a "stub" leader, i.e., one that is very short, and a template to align, position and guide the … Continue reading Driving Piles with Stub Leaders and a Template
