Safety of machinery - Electrical equipment of machines -- Part 32: Requirements for hoisting machines

This part of IEC 60204 applies to the application of electrical and electronic equipment and systems to hoisting machines and related equipment. The equipment covered by this standard commences at the point of connection of the supply to the electrical equipment of the hoisting machine (crane-supply-switch) including 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). This standard is applicable to equipment or parts of equipment not exceeding 1 000 V a.c. or 1 500 V d.c. between lines and with nominal frequencies not exceeding 200 Hz. Additional and special requirements can apply to the electrical equipment of hoisting machines including those that - are intended for use in open air (i.e., outside buildings or other protective structures); - handle or transport potentially explosive material (for example, paint or sawdust); - are intended for use in potentially explosive and/or flammable atmospheres; - 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). This standard does not cover individual items of electrical equipment other than their selection for use and their erection.

Sicherheit von Maschinen - Elektrische Ausrüstung von Maschinen - Teil 32: Anforderungen für Hebezeuge

Sécurité des machines - Équipement électrique des machines -- Partie 32: Exigences pour les appareils de levage

La CEI 60204-32 :2008 s'applique aux équipements et systèmes électriques et électroniques des appareils de levage et à leurs équipements associés. L'équipement traité dans la présente norme a pour origine le point de connexion de l'alimentation à l'équipement électrique de l'appareil de levage (sectionneur d'alimentation de l'appareil de levage), y compris l'alimentation de puissance et les alimentations de commande situées à l'extérieur de l'appareil de levage, par exemple les câbles souples, les câbles conducteurs ou les barres conductrices (voir Figure 3). Elle s'applique aux équipements ou parties d'équipements dont la tension n'excède pas 1 000 V en courant alternatif et 1 500 V en courant continu entre phases, et dont la fréquence nominale n'excède pas 200 Hz. Les appareils de levage comprennent les grues de tous types, les treuils de tous types et les machines de stockage et d'extraction. Les modifications techniques significatives par rapport à l'édition précédente sont:  - la suppression de l'Article 11 de l'édition précédente;  - la modification de la structure de la liaison équipotentielle (Article 8);  - la séparation des fonctions de commande (Article 9) et des appareils (Article 10);  - la structure de la documentation technique (Article 17);  - la vérification de la protection par coupure automatique de l'alimentation (18.2);  - le paragraphe 9.2.7 sur les commandes sans fil a été modifié.",PE
