The history of OLI Spa began in 1961, in the productive heart of Lombardy, like that of many Italian companies: small, specialized, strongly rooted in its technical know-how. The company immediately dedicated itself to the production of immersion vibrators for concrete, essential tools for compaction in civil and industrial constructions. It is a technical sector, not very visible to the general public, but decisive for the quality of the works. And Oli understands from the beginning how much the efficiency and reliability of vibration can make a difference.
