Žerjavi - Motorni vitli in dvižni mehanizmi - 2. del: Motorni dvižni mehanizmi

Ta evropski standard se uporablja za projektiranje, informacije za uporabo, vzdrževanje in preskušanje motornih dvižnih mehanizmov z vozički ali brez njih, katerih glavni pogon je električni, hidravlični ali pnevmatski motor. Zasnovani so za dvigovanje in spuščanje tovora, ki je obešen na kavlje ali druge pritrdilne elemente za dvigovanje tovora. Dvižne mehanizme je mogoče uporabiti v žerjavih, v drugih strojih, npr. regalnih dvigalih in opremi, samohodnih transporterjih ali same.
Ta evropski standard se uporablja za naslednje vrste dvižnih mehanizmov:
a) vrvni dvižni mehanizem;
b) verižni dvižni mehanizem;
c) tračni dvižni mehanizem, razen tračnega dvižnega mehanizma z jeklenimi vložki;
d) dvižni mehanizem odprtega tipa;
e) gradbene dvižne mehanizme NGL, vključno z nosilnimi konstrukcijami.
Ta evropski standard ne zajema naslednjih nevarnosti:
i) ta evropski standard ne zajema nevarnosti, povezanih z gradbenimi dvižnimi mehanizmi za prevoz blaga, kot je opredeljeno v direktivi v zvezi z emisijami hrupa v okolje (OND) 2000/14/ES;
ii) ta evropski standard ne zajema nevarnosti, povezanih z dvigovanjem oseb.
OPOMBA: Za uporabo dvižnih mehanizmov za dviganje oseb lahko veljajo posebni nacionalni predpisi.
Ta evropski standard ne določa dodatnih zahtev za nevarnosti, povezane z uporabo dvižnih mehanizmov v eksplozivnih atmosferah pri delu pod zemljo.
Posebne nevarnosti, ki jih zajema ta evropski standard, so navedene v točki 4.
Ta dokument se ne uporablja za motorne dvižne mehanizme, izdelane pred datumom izdaje tega evropskega standarda s strani CEN.
