One of the more interesting products that Vulcan spent a great deal of time on but was not able to actively pursue was the concrete pile cutter. The technology for the cutter was developed by two Soviet institutes: VNIIstroidormash in Moscow and Dalniis in Vladivostok. How Vulcan obtained the rights to the patent was an interesting process and is described here. An overview of the technology is here.
Here we link to the operations manual (or “Certificate” as the Russians referred to it.) We trust that you will find this informative as to the operation of this concrete pile cutter, which (to our knowledge) has not been duplicated elsewhere.
