With the success of the first 5′ stroke hammer, the 560, Vulcan proceeded to do the same to its successful 040/340 hammers with the 540. The first 540 was produced and sold to Conmaco and delivered in 1974. Specifications are below.
The hammer benefited from the many improvements in the 040 and the introduction went smoothly. Some general arrangements (all of which are two-sheet versions, normal for Vulcan offshore hammers at the time) are below.
Although never as popular as the 560, the hammer saw extensive service in the oilfield.
