History Edit

After a patent for a the vibration of concrete was acquired in 1934, AB Vibro Betong was founded in Stockholm, Sweden. A production plant was opened in Ljungby Sweden, as well as one in the U.S. in 1946. The latest production plant was opened in China in 2001.

In 1958, AB Vibro Betong changed its name to Dynapac, to better describe the main business in compaction machinery.[2]

Acquisitions and Joint Ventures Edit

Between 1981 and 1995, Dynapac's history has been rife with acquisitions and joint ventures that would allow it or other companies to expand in the roadbuilding construction industry.

The first acquisition occurred when Dynapac acquired roller manufacturer Watanabe from Japan in 1981. Then in 1993, Dynapac teamed up with Japanese group Hitachi. Just two years later, Dynapac acquired German asphalt power manufacturer Demag Schrader.

Dynapac was acquired first by Skanska Cement AB in 1964 and then went on to become a division of Atlas Copco Road Construction Equipment in 2007, although it operates separately within the construction and mining technology business division.[3]

Acquisition by Atlas Copco Edit

Atlas Copco has been in the business for more than 130 years, specializing in three areas: Compressor Technique, Construction and Mining Technique and Industrial Technique. Its headquarters are based in Sweden and it has approximately 27,000 employees.[4]

Atlas Copco wanted to expand the market and thus acquired Dynapac in 2007 to help establish its presence in construction and provide a more extensive line of products and services. The acquisition also enabled the company to open up the construction market in other countries around the world that are building roads, such as China and India.[5]

The purchase price was BSEK 6.3 (MEUR 700) with about BSEK 2.1 associated debt. With the agreement of Altor 2003 Fund, Atlas Copco purchased Dynapac.[6]

Upon acquisition, former Dynapac CEO Ronald Kok was made a board member of the Road Construction Equipment Division. Atlas Copco president Claes Ahrengart was appointed president of the newly acquired division.[7]

Vibratory Roller Edit

Dynapac, while it was known as AB Vibro Betong, launched the first vibratory roller in 1947. Compaction rollers are construction tools used to compact a variety of surfaces such as concrete, soil, and gravel, usually during the construction of roadways. They function by utilizing the vehicle's weight to compress the surface. Compaction was initially carried out by air-filled tired rollers.

While AB Vibro Betong did not invent rollers, it first launched them into production. The roller was actually invented by Hamm AG, now part of the Virtgen Groub GmbH  of Germany in the early 1900s.[8]
