PTC of Paris, France originally invented the concrete vibrator in 1928and the vibodriver in the 1950's. In the early 1970's they developed hydraulic drivers for deep underwater applications and introduced high frequency vibrodrivers in 1982. In 1992 PTC patented the HFV system(high frequency, variable eccentric) capable of cross critical frequencies without transmitting vibrations to the surroundings. PTC's models include the world's largest vibratory hammer, the PTC 240HD, known as the Red Bull.

American Equipment began its association with PTC in 1998.
