Using a Vulcan #2 for Residential Piling

Most residences do not require pile foundations, but some do, generally because of the combination of the size of the house and the geotechincal stratigraphy (read soft.) In Vulcan's history this is generally associated with the New Orleans area, but recently a Vulcan #2 was used to drive residential piling in Connecticut. The whole post … Continue reading Using a Vulcan #2 for Residential Piling

Pile Driving Part III: Installation Equipment — Pile Buck Magazine

View Part II of this article here. Over time, the technology for pile installation has led to the development of hammers that are both larger and faster. From rams that were raised by humans or horses to steam, air, and hydraulic hammers to double acting hammers, this equipment is an essential part of any construction… via … Continue reading Pile Driving Part III: Installation Equipment — Pile Buck Magazine

No, the Cut-In Height Didn’t Cause the “Downfall” of the Air Hammers

There's an urban legend going around social media these days that states that the "demise" (which is hardly true since they're still in use) of air hammers is due to the fact that the valve admits air to the cylinder before impact, thus slowing down the ram.  This legend has it that this was detected … Continue reading No, the Cut-In Height Didn’t Cause the “Downfall” of the Air Hammers

Aboard the Giant Sand-Sucking Ships That China Uses to Reshape the World

From this: As steam power gave way to diesel in the late 19th century, the size and power of dredges grew. Developers in Los Angeles used centrifugal pumps to expand the city’s port and turn marshlands into seaside real estate. Sediment dredged from underwater built Boston’s Back Bay, as well as large portions of Marseilles, … Continue reading Aboard the Giant Sand-Sucking Ships That China Uses to Reshape the World

The Old “Toilet Paper” Trick for Piston Rings Takes on a New Meaning

The vulcanhammer.info Guide to Pile Driving Equipment features the field service manual for the DGH series hammers.  Here we find the following advice during the replacement of the piston ram: Place 1" (25mm) wide pieces of soluble paper (such as toilet paper) between the piston and lower ring grooves. Push the rings and paper into … Continue reading The Old “Toilet Paper” Trick for Piston Rings Takes on a New Meaning

A Gathering for Energy Savings

Above is an unusual photo from Vulcan's archives: a gathering for a test for the Vulcanaire Supertherm at the yard of Horn Pile and Foundation Corp. in Bellmore, Long Island, NY, 16 November 1964.  It's the rare gathering in the construction (or just about any other) industry where everyone arrives in suits, but here they … Continue reading A Gathering for Energy Savings

“Much Favorable Comment” for the Vulcan Extractor

An ad in Engineering News-Record, 8 October 1931, for the Vulcan Pile Extractor.  It was used to extract arch web Lackawanna sheeting by the P.J. Kennedy & Co. of Holyoke, MA.  Vulcan touted the advantages of a "single purpose machine" (as opposed to MKT's multipurpose hammer/extractors.  MKT must have gotten the message, they developed the … Continue reading “Much Favorable Comment” for the Vulcan Extractor

When the Vulcan #2 Beat the MKT 9B2

Above is a job comparison from 1926, put together by the firm Proctor and Cleghorn of Santa Rosa, CA, showing the Vulcan #2--to say nothing of the #1 also--significantly outperforming the MKT 9B2 (which they superseded with the 9B3) driving concrete piles.  Vulcan obtained this data from Harron, Rickard & McCone, Vulcan's dealer in California. … Continue reading When the Vulcan #2 Beat the MKT 9B2

How Vulcan Extractors Work

Vulcan was generally not hesitant to include information on the cycle workings of its air/steam hammers, but for some reason never included similar information on its extractors.  Above is a diagram from 1940 which shows how this is done. Basically we start with the view on the left.  Air or steam is admitted through inlet … Continue reading How Vulcan Extractors Work
