Safety of machinery - Electrical equipment of machines - Part 32: Requirements for hoisting machines
This part of IEC 60204 applies to electrical, electronic, programmable electronic equipment and systems to hoisting machines and related equipment, including a group of hoisting machines working together in a co-ordinated manner NOTE 1 In this part of IEC 60204, the term "electrical" includes both electrical and electronic matters (i.e. "electrical equipment" means both the electrical, electronic and programmable electronic equipment). NOTE 2 In the context of this part of IEC 60204, the term “person” refers to any individual and includes those persons who are assigned and instructed by the user or user’s agent(s) in the use and care of the hoisting machine in question. The equipment covered by this part of IEC 60204 commences at the point of connection of the supply to the electrical equipment of the hoisting machine (crane-supply-switch) and includes systems for power supply and control feeders situated outside of the hoisting machine, for example, flexible cables or conductor wires or conductor bars (see Figure 3). NOTE 3 The requirements for the electrical supply installation of electrical equipment of a hoisting machine are given in IEC 60364. This standard is applicable to equipment or parts of equipment not exceeding 1 000 V AC or 1 500 V DC between lines and with nominal frequencies not exceeding 200 Hz. NOTE 4 Special requirements for electrical equipment of hoisting machines intended to be operated at higher voltages, see IEC 60204-11 (Annex D) This part of IEC60204 does not cover all the requirements (for example guarding, interlocking, or control) that are needed or required by other standards or regulations in order to protect persons from hazards other than electrical hazards. Each type of hoisting machine has unique requirements to be accommodated to provide adequate safety. This part of 60204 doesn´t cover noise risks and vibration risks. Additional and special requirements can apply to the electrical equipment of hoisting machines including those that - handle or transport potentially explosive material (e.g. paint or sawdust); - are intended for use in potentially explosive and/or flammable atmospheres; - have special risks when transporting or moving certain materials - are intended for use in mines. For the purposes of this standard, hoisting machines include cranes of all types, winches of all types and storage and retrieval machines. The following product groups are included: - overhead travelling cranes; - mobile cranes; - tower cranes; - slewing luffing cranes; - gantry cranes; - offshore cranes; - floating cranes; - winches of all types; - hoists and accessories; - loader cranes; - cable cranes; - load holding devices; - storage and retrieval machines; - monorail hoists; - straddle carriers; - rubber tyred gantry cranes (RTGs). NOTE 5 Definition of the different crane types see ISO 4306-1 This standard does not cover individual items of electrical equipment other than their selection for use and their erection.

Des exigences complémentaires et particulières peuvent s’appliquer aux équipements électriques des appareils de levage, y compris ceux qui: – manipulent ou transportent des matériaux potentiellement explosifs (par exemple, de la peinture ou de la sciure); – sont destinés à être utilisés dans des atmosphères potentiellement explosives et/ou inflammables; – présentent des risques particuliers lors du transport ou du déplacement de certains matériaux; – sont destinés à être utilisés dans des mines. Pour les besoins du présent document, les appareils de levage comprennent les grues de tous types, les treuils de tous types et les machines de stockage et d'extraction. Les familles de produits suivantes sont incluses: – ponts roulants; – grues mobiles; – grues à tour; – grues pivotantes à flèche relevable; – portiques; – grues offshore; – grues flottantes; – treuils de tous types; – palans et accessoires; – grues de chargement; – grues à câble (blondins); – accessoires de suspension de charge; – machines de stockage et d'extraction; – treuils suspendus avec rail de translation fixe; – enjambeurs; – portiques sur pneus. Le présent document ne traite pas les éléments particuliers de l'équipement électrique, sauf pour leur choix et leur mise en œuvre. L'IEC 60204-32:2023 annule et remplace la deuxième édition parue en 2008. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l’édition précédente: a) L'alignement sur la sixième édition de l’IEC 60204-1 (2016) notamment pour: – les exigences relatives à la mise à la terre et à la liaison; – les exigences en matière de protection des circuits; – l'examen de l'utilisation des entraînements électriques de puissance (PDS); – les exigences et la terminologie relatives aux liaisons de protection; – les exigences relatives au couple de sécurité pour les PDS, l'arrêt d'urgence et la protection des cir
Varnost strojev - Električna oprema strojev - 32. del: Posebne zahteve za dvigalne stroje (IEC 60204-32:2023)
Ta del standarda IEC 60204 se uporablja za električno, elektronsko, programirljivo elektronsko opremo in sisteme za dvigalne stroje ter povezano opremo, vključno s skupino dvigalnih strojev, ki delujejo skupaj in usklajeno. OPOMBA 1: V tem delu standarda IEC 60204 izraz »električno« vključuje tako električne kot elektronske zadeve (tj. »električna oprema« pomeni tako električno, elektronsko kot tudi programirljivo elektronsko opremo). OPOMBA 2: V okviru tega dela standarda IEC 60204 se izraz »oseba« nanaša na posameznike in vključuje tiste osebe, ki jih uporabnik ali njegov zastopnik določi ali usposobi za uporabo ter vzdrževanje zadevnega dvigalnega stroja. Oprema, ki je zajeta v tem delu standarda IEC 60204, se začne v točki priključitve napajanja z električno opremo dvigalnega stroja (žerjav-napajanje-stikalo) ter vključuje napajalne sisteme in kontrolne vhode, ki se nahajajo zunaj dvigalnega stroja, na primer zvijave kable, prevodne žice ali prevodne zbiralke (glej sliko 3). OPOMBA 3: Zahteve za električne inštalacije za napajanje električne opreme dvigalnega stroja so podane v standardu IEC 60364. Ta standard se uporablja za opremo ali dele opreme z največjo izmenično napetostjo 1000 V oziroma enosmerno napetostjo 1500 V med vodi, pri čemer nazivna frekvenca ne presega 200 Hz. OPOMBA 4: Posebne zahteve za električno opremo dvigalnih strojev, namenjenih za delovanje pri višjih napetostih, so podane v standardu IEC 60204-11 (dodatek D). Ta del standarda IEC 60204 ne zajema vseh zahtev (na primer varovanja, spajanja ali nadzora), ki so potrebne ali zahtevane zaradi drugih standardov ali predpisov za zaščito oseb pred nevarnostmi, ki niso pogojene z virom električne energije. Vsaka vrsta dvigalnega stroja vključuje edinstvene zahteve, ki jih je treba izpolniti za zagotovitev ustrezne varnosti. Ta del standarda 60204 ne zajema nevarnosti zaradi hrupa in tresljajev. Dodatne in posebne zahteve lahko veljajo za električno opremo dvigalnih strojev, ki: – se uporabljajo za transport potencialno eksplozivnega materiala (npr. barve ali žagovine) ali rokovanje z njim; – so namenjeni uporabi v potencialno eksplozivnih in/ali vnetljivih atmosferah; – predstavljajo posebna tveganja pri transportu ali premikanju nekaterih materialov; – so namenjeni uporabi v rudnikih. V tem standardu dvigalni stroji vključujejo žerjave vseh vrst, vitle vseh vrst ter stroje za skladiščenje in prevzem. Vključene so naslednje skupine izdelkov: – tekalni žerjavi; – premični žerjavi; – stolpni žerjavi; – vrtljivi/prevesni žerjavi; – portalni žerjavi; – žerjavi na plavajočih objektih; – plavajoči žerjavi; – vitli vseh vrst; – dvigala in dodatna oprema; – nakladalni žerjavi; – kabelski žerjavi; – naprave za držanje bremen; – stroji za skladiščenje in prevzem; – samohodna dvigala; – nakladalniki; – portalni žerjavi z gumijastimi kolesi (RTG). OPOMBA 5: Za opredelitev različnih vrst žerjavov glej standard ISO 4306-1. Ta standard ne zajema posameznih kosov električne opreme, razen njihove izbire za uporabo in njihove postavitve.
