The roots of today's Hiab Company lie in a series of acquisitions from 1977 onwards, when Partek Corporation embarked on a comprehensive diversification and internationalization strategy. Founded in 1898, Partek Corporation was one of the oldest industrial companies in Finland, originally producing limestone and later a versatile range of materials for the construction industry. In 1977, Partek decided to expand into the engineering industry and thereby decrease its dependence on domestic construction when it first bought the 'Multilift' brand. Eight years later, 1985 the company bought 'Hiab' with its forestry crane subsidiary Jonsered. 1988 they bought Loglift, as the name implies, also a forestry crane manufacturer.
