Cranes - Loader cranes

This European Standard specifies minimum requirements for design, calculation, examinations and
tests of hydraulic powered loader cranes and their mountings on vehicles or static foundations.
This European Standard does not apply to loader cranes used on board ships or floating structures or to
articulated boom system cranes which are designed as total integral parts of special equipment such as
forwarders.
The hazards covered by this standard are identified in Clause 4.
This European Standard does not cover hazards related to the lifting of persons.
This European Standard is not applicable to loader cranes which are manufactured before the date of its
publication as EN. #The amended provisions concerning stress calculations are not compulsory for
cranes designed before the date of availability of EN 12999:2011+A2:2017.$
NOTE The use of cranes for lifting of persons can be subject to specific national regulations.

Žerjavi - Nakladalni žerjavi

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. #Spremenjene določbe v zvezi z izračuni napetosti niso obvezne za žerjave, ki so bili zasnovani pred datumom razpoložljivosti standarda EN 12999:2011+A2:2017.$
OPOMBA: Za uporabo žerjavov za dviganje oseb lahko veljajo posebni nacionalni predpisi.
