SHORT HISTORY

The manufacturing tradition of gear and powertrain components in the ZZN at LiuGong Dressta Machinery  dates back to the 70’s of the last century. The company was originally formed by Huta Stalowa Wola in order to supply high quality products employed in the construction equipment manufactured in Stalowa Wola, Poland.

Developing its technologies and production capacity, the plant eventually became a  significant supplier of gears and toothed units for the leading construction, railway and  agriculture equipment manufacturers worldwide and in Poland. By the mid 90’s, the plant was Poland’s leading manufacturer of driveline components.

Since its formation, the ZZN has been focused on producing high  quality geared components. After 40 years of refining and perfecting all driveline  components, the Plant continuously offers world-class production quality, skilled and  experienced personnel, along with vast know-how and large  technological capabilities – all major factors which have  helped the company thrive.

Now, the ZZN  is one of the organizational units of LiuGong Dressta Machinery Co.Ltd.
