The 014 and 016 hammers were the first single-acting hammers Vulcan produced based on the Super-Vulcan design. The main difference between the two was the ram weight, as can be seen below.
These hammers are without the Vari-Cycle feature; the drawing at the very top shows the Vari-Cycle added.
Specifications for the onshore hammers (which sported 32″ female jaws) are below.
The 016 was the basis of the Conmaco 160, which Vulcan first produced for Conmaco before they “struck out on their own.”
Vulcan also produced these hammers in an offshore configuration with 54″ male jaws, as shown below. The first of these was for Ingram Contractors (at the time the same ownership as the book distribution company) in 1968. T.L. James and McDermott also purchased these hammers.
Specifications for the offshore hammers are below.
One major difference between the offshore and onshore models is the raised vs. lowered steam chest. The onshore model cylinder design was modelled after the Super-Vulcan hammers, which required a steam chest raised above the bottom of the cylinder. For the offshore hammers this was dispensed with and the steam chest design was more like the Warrington-Vulcan hammers, low on the cylinder. The main benefits were a shorter slide bar and less chance for core burn-in in the air/steam passages.
The heavier build of these hammers (as opposed to the earlier single-acting hammers) was more beneficial offshore than onshore. The frame is more durable (although it’s hard to argue with a configuration that lasts 120 years!) but this added to the weight. One place that could have been a significant advantage is with 5′ stroke versions (514 and 516) of the hammers, which were proposed in the 1980’s. As shown below, these were considered for both onshore and offshore designs. The problem with these hammers was that they were too late: had they been proposed in the 1960’s as the offshore oil industry was working its way up the energy scale, the result would have been hammers with 70,000-80,000 ft-lbs of energy in a frame lighter than the 020.
The weight of the 014 and 016 may have put them at something of a disadvantage, but they have given good service in the sixty-years they’ve been out, as can be seen in this video (courtesy of Pile Hammer Equipment.)
