b) chain hoist;
c) belt hoist, except belt hoist with steel belts as hoisting media;
d) open type hoist;
e) NGL building hoists including supporting structures.
This European Standard is not applicable of the following hazards:
i) this European Standard does not cover hazards related to builders hoists for the transport of goods as defined in Noise Outdoor Directive (OND) 2000/14/EC;
ii) this European Standard does not cover hazards related to the lifting of persons.
NOTE The use of hoists for the lifting of persons may be subject to specific national regulations.
This European Standard does not specify additional requirements for hazards related to the use of hoists in explosive atmospheres in underground works.
The significant hazards covered by this European Standard are identified in Clause 4.
This document is not applicable to power driven hoists which are manufactured before the date of publication of this European Standard by CEN.

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.
