Driving Speed That Makes Footage Records

Above, an ad for the Warrington-Vulcan hammer, as featured in Engineering News-Record, 1926.  Note that there are two distributors listed: one in California and the venerable Woodard Wight in New Orleans, which (with its salesman Herman Hasenkampf) went on to represent Vulcan in the Gulf during the offshore years.

Note also that Vulcan even at this date already had a “half century of experience in the design and manufacture of pile-driving equipment.”  It also touted (before the advent of diesel hammers) the advantage of “heavy ram-low velocity” which still has its advantages today.
