In 1975, by Government Decision, Intreprinderea de Utilaj Greu was founded in Craiova, a modern industrial unit located on an area of ​​111.00 square meters, situated in the city’s eastern industrial platform. The enterprise had as main activity designing, manufacturing and trading heavy duty, specialized, on theme machine tools; complex technological equipment for the metallurgical, steel, chemical, energy, mining, pulp, paper and wood processing industries. 

The technical equipment of the company was outstanding, very complex and large machine tools were being purchased from famous companies from Germany, France, Japan, UK, USA, Italy. The technological capacities, along with the fact that it was located on the route Bucharest-Timisoara, having access to Bechet port on the Danube and Craiova Airport, turned Intreprinderea de Utilaj Greu Craiova in an ideal partner and manufacturer of complex large-sized equipment.

Since 1978 the company has produced heavy machine tools under the license of well-known industrial companies in the field: Toshiba-Japan LINE – France H.Ernault – France. These were made for export or equipping other plants in the country.

In 1985 IUG Craiova became building partner to the construction of the Cernavoda Nuclear Power Plant, providing a range of components for it.

In 1990, after the subversion of the Communist regime, by the Romanian Government Decision no. 1327/1990, the Intreprinderea de Utilaj Greu became a stock company. At that time it was reorganized, three factories functioning within it: machine tools factory, technical equipment factory and welded mechanical plant; and two autonomous sections: mechanical energy and toolroom section. Unlike other similar units that were profiled on series production, IUG SA maintained its character of unique items producer, having a great technological flexibility.

In 1995, Intreprinderea de Utilaj Greu became the first Romanian company in the industry that has been certified by the prestigious firm Germanischer Lloyd, according to ISO standard 9001:1994. However, in a young competitive market, on the background of the changes that occurred in the 90’s, the company has experienced a downward trend, being forced to severely restrict activity. 

In 2002, IUG SA Craiova becomes Popeci Utilaj Greu SA, a stock company with entirely private capital, part of the Popeci Group and having Mr. Constantin Popeci as major shareholder, who also occupies the Chairman position. At the time of the takeover, the company had 490 employees, 58 working in design and 33 in the quality assurance department.

In 2008, the company has implemented and certified the Integrated Management System: Quality according to ISO 9001:2008, Environment according to SR EN ISO 14001:2005 Health & Safety according to SR OHSAS 18001:2008 as; leading to improved quality of products and services and automatically to an improvement of the company’s image on internal and external markets.

As a result of the increasing number of orders, the number of employees has also increased, in 2008 being recorded a total of 690 persons of which approximately 75% involved in the production process.

In the next period the company’s activity saw an upward trend, shown as an increase of the production and of the turnover from year to year, this allowing the allocation of funds for modernization and upgrading production capacities.
