Dynapac is a Swedish multinational engineering company located in Karlskrona.
In 1947 it launched the first vibratory plate compactor, which weighed 1.5 tonnes, being nicknamed the frog.
The site in Karlskrona opened in 1960, which made heavy rollers and had the company's technical centre.
It changed its name to Dynapac Maskin AB in 1973; at this moment the company rapidly expanded its product range.
