The Vulcan 50-C is the double acting version of the Vulcan #1. It has the same ram size and delivers very similar striking energy. The double acting version of the hammer is better in non-cohesive soils such as sand, silt and gravel. With a standard base, the hammer can be set up with a helmet to drive a variety of steel piles. The McDermid base version is designed to drive timber pile without the use of a helmet.
