On my companion site vulcanhammer.info, I have posted several articles on Soviet (and after that Russian) pile driving equipment, such as diesel hammers, concrete pile cutters, and vibratory and impact-vibration hammers. These are very specialised topics, even by construction industry standards; here I want to present some photos of more general interest to you heavy equipment fans. The Soviet Union was known for its commitment to heavy manufacturing and construction equipment like this is certainly a big part of that.
NPO VNIIstroidormash is the Soviet name for the Moscow-based institute which designed and tested the equipment shown below. The name means the All-Union Scientific Research Institute of Construction and Road-Building Machinery. It was put together in 1975, and survived past the end of the Soviet Union in 1991 as a share society, i.e., a privatised corporation. In addition to the pile driving equipment which got me involved with the organisation, it designed many other types of equipment, and the best way to show this follows, from their catalogue produced around 1986.
Our family business first connected with the Institute in 1988, and our contacts continued for the next six years. Sometimes things got strange but we discovered an organisation that put out some very good designs for construction equipment. Unfortunately the Soviet manufacturing organisation was not up to proper quality control, especially in the civilian sector, and that weakness was one of those which ultimately brought the Soviet Union down.
