Raymond 60X Hammer

Raymond Concrete Pile Company (later Raymond International) was in its day the greatest pile driving organisation in the world. It either developed or perfected many of the techniques which are standard for designing and installing driven piles today. The most significant of these was the wave equation, the brainchild of Raymond's chief mechanical engineer, E.A.L. … Continue reading Raymond 60X Hammer

Driving Steel Piles Wild

A few months back we posted Driving Concrete Piles Wild, which documented a Vulcan 020 being used on a project to drive concrete cylinder piles wild. Below is a video of a Vulcan 016 driving steel piles wild: https://youtu.be/t4Zh5ZaeVgc Vulcan 016 driving a steel pile pile wild. Contractor is J.E. Borries; video courtesy of Pile Hammer … Continue reading Driving Steel Piles Wild

Weight of Vulcan Wood Pile Caps for Wave Equation Analysis

In the late 1980's Vulcan furnished GRL with extensive information on its hammers, cushion configurations and cap weights for what was then the WEAP86/WEAP87 program. Most of that was carried over into the GRLWEAP program. One item that is not well represented in the database are the weights for the wood caps. From a Vulcan … Continue reading Weight of Vulcan Wood Pile Caps for Wave Equation Analysis

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
