At one point or another in its history, Vulcan attemped to produce or market every type of pile driver made. Probably the persistently least successful type were the diesel hammers. Vulcan's failure to manufacture and/or market a widely accepted diesel hammer was a significant long-term problem for the company.

Nevertheless diesel hammers are an important and interesting type of impact pile driver. This section of vulcanhammer.info discusses diesel hammers in general and Vulcan's several attempts to enter the market.

• Beginnings of Diesel Hammers in the U.S., and Vulcan's First Response: the IC-65
• Nilens--Vulcan's Belgian import, and in many ways the most successful of Vulcan's diesel offerings
• Liquid Propane Gas (LPG) hammer--an adaptation of the Nilens hammer to address the issue of pollution
• The IC-30/30D/33D Hammers: Vulcan's own diesel that made it to market--sort of
• The "V" series diesel, Vulcan's adaptation of Russian diesel hammers and its last attempt at a diesel hammer
