Les phénomènes dangereux couverts par la présente norme européenne sont identifiés à l'Article 4.
La présente Norme européenne ne couvre pas les phénomènes dangereux relatifs au levage de personnes.
La présente Norme s’applique aux grues de chargement fabriquées après la date d'approbation de cette norme par le CEN.
NOTE L’utilisation d’appareils de levage pour le levage de personnes peut être soumise à des réglementations nationales spécifiques.
Žerjavi - Nakladalni žerjavi (vključno z dopolnilom A1)
Ta evropski standard določa minimalne zahteve za konstrukcijo, izračun, preglede in preskuse hidravličnih nakladalnih žerjavov ter njihovih elementov za pritrditev na vozila ali statične podlage. Ta evropski standard se ne uporablja za nakladalne žerjave, ki se uporabljajo na krovu ladij ali plavajočih konstrukcij, ali žerjave s členjeno roko, ki so konstruirani kot skupni sestavni deli posebne opreme, kot so zgibni polpriklopniki. Nevarnosti, ki jih zajema ta standard, so opredeljene v točki 4. Ta evropski standard ne zajema nevarnosti v zvezi z dviganjem oseb. Ta evropski standard se ne uporablja za nakladalne žerjave, ki so bili izdelani, preden je bil objavljen kot standard EN.
