The photo above, dating from 1949, shows a worker tightening the bolts on the connecting links of a Vulcan extractor to the top of a prepared sheet piling in preparation to impact the sheeting upwards and take it out. This photo was used for many years in Vulcan literature, including Vulcan Bulletin 71B. (Note: don’t try this now without a safety belt and other safety equipment for the worker!)
The project it was on was in familiar country to Vulcan: it was for the Calcasieu River Bridge between Westlake and Lake Charles, LA. The owner was the State of Louisiana Department of Highways. The contractors were Kansas City Bridge and Massman Construction, still a user of Vulcan and Conmaco equipment.
It’s also interesting because it’s similar to the “sheet pile setter” logo that Pile Buck has used for many years in its own logo and advertising.
