It is known that vibrating hammers (impact-vibration hammers) are highly effective for driving pipes. However, their wide use is prevented by their insufficient durability and high energy consumption, which are determined mainly by the high velocity of the hammer at the moment of impact against the driven element. The results of the investigations described in this article indicate that the driving capacity of vibrating hammers in soils of medium density can be improved without increasing the impact velocity, by increasing the length of the path travelled jointly by the hammer and the pipe after each blow. When the vibrating hammer operates under longitudinal action, the above-mentioned effect can be obtained by adjusting the force in the springs, in case of large negative gaps. High driving capacity is possessed also by vibrating hammers operating under longitudinal-rotary action, in which the path traveled jointly by the hammer and the pipe is increased. as a result of torsional vibrations of the driven pipe.

This article is an overview of both the development and present status of impact-vibration hammer, with special emphasis on the situation in the Russian Federation. This last point is significant because the technology was originally developed there. An appendix to explain unfamiliar aspects of the old Soviet economic system as they relate to this article is also included, as is a bibliography.
An extract from a Soviet book on the subject of vibratory pile drivers, showing the types of vibratory drivers in use in the late Soviet period and also some of the other machines available (especially the Japanese units.) Also includes the Savinov and Luskin method for sizing a vibratory hammer for a particular application.
