CPV code 42420000 designates Buckets, shovels, grabs and grips for cranes or excavators in the Common Procurement Vocabulary (CPV 2008), the EU classification used to describe the subject of public contracts.
42420000 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 42400000 (Lifting and handling equipment and parts).
