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

If You’re Not Going to Use a Head Sheave, Use a Bar or Suspension Type Head

In Vulcan Onshore Tip 65, the safe use of sheave type cylinder heads is discussed. A view of the different types of sheave/sheave head/sheave pin/retaining pins from that tip are shown at the right. In the a more recent post, a more detailed diagram of a sheave head is shown below. Some Vulcan users feel … Continue reading If You’re Not Going to Use a Head Sheave, Use a Bar or Suspension Type Head

A Nice Vulcan Hammer Model From One of its Users

Models of Vulcan hammers--working or otherwise--are rare. This one comes from the Boston area, made by one of the pile drivers who worked the Boston waterfront. It is a real gem; I have not seen one this good in a long time. The "front" view of the hammer model. Traditionally Vulcan hammers were run with … Continue reading A Nice Vulcan Hammer Model From One of its Users

Vulcan’s Sight Feed Line Oilers

Proper lubrication is essential to just about any type of moving machinery, and Vulcan's pile drivers are no exception. The most important single point of lubrication is the steam or air cylinder which pulls up (and with some hammers pushes down) the cylinder. Failure to do this will result in reduced efficiency and expensive repairs, … Continue reading Vulcan’s Sight Feed Line Oilers

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
