Jungheinrich System Error Codes list

Service technicians have no problem recognising breakdowns and carrying out machine diagnostics, Jungheinrich System Error Codes list, plus they are familiar with equipment from a variety of manufacturers.

Jungheinrich AG is a German company active in the material handling equipment, warehousing and material flow engineering sectors. In these segments, the company is ranked in second place in Europe, and third in the world. Friedrich Jungheinrich founded H. Jungheinrich & Co. Maschinenfabrik on 7 August 1953 in Hamburg. The first foreign branch was opened in Austria in 1956. In 1958, the company headquarters opened with a plant in Hamburg-Wandsbek. On 11 July 1960 Jungheinrich AG was founded as a Swiss subsidiary under the name “Ameise GmbH”, headquartered in Aarau. The product range is divided into four pillars: industrial trucks such as forklift trucks, high-bay stackers and tractors. The best-known product is the ‘Ameise’ (Ant). It is a registered trademark of Jungheinrich Profishop and is frequently used as a synonym for manual or electric pallet trucks.
