In 1918, the town of Hoboken, Pennsylvania, where the company was located, changed its name to Blawknox. In 1927, the company expanded into radio tower production. With the acquisition of the A.W. French Company in 1929, the Blaw-Knox Company began producing paving equipment. The company became part of Volvo's construction producing division in 2007.
