CPV code 42414500 designates Bridge cranes in the Common Procurement Vocabulary (CPV 2008), the EU classification used to describe the subject of public contracts.
42414500 is a leaf code — the most specific level of its branch — so it can be used directly as the main CPV code of a contract notice. If it does not quite fit, check the neighbouring codes under 42414000 (Cranes, mobile lifting frames and works trucks fitted with a crane).
