Machines for compacting waste materials or recyclable fractions - Horizontal baling presses - Safety requirements
This European Standard specifies the safety requirements for the design, manufacture and information for safe use of horizontal baling presses for compacting waste material or recyclable fractions (e.g. paper, plastics, textiles, cans, cardboard, mixed waste), hereafter referred to as materials. It covers only machines fed by conveyors or by feed hoppers where the bales are bound manually or automatically. The feed hoppers covered by this European Standard are only fed mechanically or by hand. The scope of this European Standard includes any mechanical feed equipment, such as belt type loading and feed conveyors or bin lifts, forming an integral part of the baling press assembly. However, pneumatic conveying systems are outside the scope of this European Standard. This European Standard does not apply to cranes, lift trucks or other mobile plant used to load materials into the feed hopper. Nor does it apply to hazards arising from loading the feed hopper using cranes, lift trucks or other mobile plant. This European Standard does not apply to pre-conditioning equipment connected at the inlet side of the feed hopper (e.g. sorter, shredder, stand-alone perforator), nor to equipment at the outlet side of the baling press. This European Standard does not deal with suction and de-dusting mechanisms. This European Standard does not apply to hazards arising from the materials being processed (e.g. asbestos, clinical waste, aerosol containers). This European Standard does not cover risks arising from installation of baling presses in places accessible to the public. All hazards mentioned in Clause 4 are dealt with in this European Standard. This European Standard is not applicable for horizontal baling presses which are manufactured before the date of its publication as an European Standard.
Maschinen zum Verdichten von Abfällen oder recyclebaren Materialien - Horizontal arbeitende Ballenpressen - Sicherheitsanforderungen
Diese Norm legt die Sicherheitsanforderungen für die Gestaltung, den Bau und die Benutzerinformation von
horizontalen Ballenpressen zum Verdichten von Abfällen oder recyclebaren Materialien (z. B. Papier, Plastik,
Textilien, Dosen, Pappe, gemischte Abfälle), nachstehend „Material“ genannt, fest. Die Norm behandelt
ausschließlich Pressen, die mittels Förderbändern oder Zufuhrtrichtern beschickt und in welchen die Ballen
entweder händisch oder automatisch verschnürt werden. Diese Norm erfasst ausschließlich mechanisch oder
händisch beschickte Zuführtrichter.
Der Anwendungsbereich der Norm gilt für automatische Beschickungseinrichtungen wie Förderbänder als
Aufgabe- und Zuführförderer oder Kippvorrichtungen, die integraler Bestandteil der Ballenpresse sind, mit
Ausnahme von pneumatischen.
Die Norm gilt nicht für Krane, Gabelstapler oder andere mobile Maschinen, die für die Zufuhr von Material
zum Aufgabeschacht eingesetzt werden. Ebenso gilt sie nicht für Gefährdungen, die durch den Einsatz von
Kranen, Gabelstaplern oder anderen mobilen Maschinen beim Beschicken des Aufgabeschachts entstehen.
Die Norm gilt weder für Vorbehandlungsanlagen auf der Zuführseite des Aufgabeschachts (z. B. Sortiereinrichtungen,
Shredder, eigenständige Perforatoren), noch für Anlagen auf der Auslassseite der Ballenpresse.
Sie behandelt keine Absaug- oder Entstaubungsanlagen.
Sie gilt nicht für Gefährdungen, die durch die verarbeiteten Materialien (z. B. Asbest, Klinikabfälle,
Sprühdosen) entstehen.
Alle in Abschnitt 4 aufgeführten Gefährdungen werden in dieser Norm behandelt.
Machines de compactage pour déchets ou matières recyclables - Presses à balles horizontales - Prescriptions de sécurité
La présente norme spécifie les prescriptions de sécurité applicables à la conception, à la construction et aux
informations pour l’utilisation en sécurité des presses à balles horizontales qui sont utilisées pour compacter
des déchets ou des matières recyclables (papier, plastique, textiles, canettes et boîtes de conserve, carton,
déchets mélangés, par exemple), ci-après désignés sous le terme de « matériaux ». Elle ne s’applique qu’aux
machines alimentées par convoyeurs ou par trémies d’alimentation sur lesquelles les balles sont ligaturées
manuellement ou automatiquement. Les trémies d’alimentation couvertes par la présente norme sont
exclusivement chargées mécaniquement ou manuellement.
Le domaine d’application de la présente norme couvre tout équipement d’alimentation mécanique faisant
partie intégrante de l’installation de mise en balles, tel que convoyeur à bande de chargement et
d’alimentation ou lève-conteneur. Les convoyeurs pneumatiques sont toutefois hors du domaine d’application
de la présente norme.
La présente norme ne s’applique pas aux grues, chariots industriels ou autres engins mobiles utilisés pour
charger les matériaux dans la trémie d’alimentation. Elle ne s’applique pas non plus aux phénomènes
dangereux résultant du chargement de la trémie d’alimentation au moyen de grues, de chariots industriels ou
d’autres engins mobiles.
La présente norme ne s’applique ni aux équipements de pré-conditionnement raccordés en amont de la
trémie d’alimentation (trieuse, déchiqueteuse, perforateur indépendant, par exemple), ni aux équipements
installés en aval de la presse à balles. Elle ne traite pas des mécanismes d’aspiration et de dépoussiérage.
Elle ne s’applique pas aux phénomènes dangereux liés aux matériaux traités (amiante, déchets médicaux,
générateurs d’aérosols, par exemple).
Tous les phénomènes dangereux mentionnés à l’Article 4 sont traités dans la présente norme.
Stroji za stiskanje odpadkov ali reciklirnih materialov - Vodoravno delujoče stiskalnice za bale - Varnostne zahteve
Ta evropski standard določa varnostne zahteve za obliko, izdelavo in informacije za varno uporabo vodoravno delujočih stiskalnic za bale za stiskanje odpadkov ali reciklirnih materialov (npr. papirja, plastike, tekstila, pločevine, kartona, mešanih odpadkov), v nadaljevanju: materiali. Vključeni so samo stroji, ki se napajajo iz tekočih trakov oziroma naprav za odmerjanje hrane, pri katerih se bale vežejo ročno ali avtomatsko. Naprave za odmerjanje hrane, obravnavane v tem evropskem standardu, se napajajo samo mehansko ali ročno. Področje uporabe tega evropskega standarda vključuje vso mehansko opremo za odmerjanje hrane (npr. tračni način nalaganja in naprave za odmerjanje hrane oziroma stroje za dviganje), ki tvori nepogrešljiv del sestavov za stiskanje bal. Pnevmatski sistemi za prenos ne spadajo na področje uporabe tega evropskega standarda. Ta evropski standard ne velja za dvigala, viličarje ali druge premične obrate, ki se uporabljajo za nalaganje materialov v naprave za odmerjanje hrane. Prav tako ne velja za nevarnosti, ki izvirajo iz nalaganja naprav za odmerjanje hrane z uporabo dvigal, viličarjev ali drugih premičnih obratov. Ta evropski standard ne velja za opremo za predhodno pripravo, povezano z vhodno stranjo naprave za odmerjanje hrane (npr. naprava za sortiranje, drobilnik, samostoječi perforator), in za opremo na izhodni strani stiskalnice bal. Ta evropski standard ne obravnava mehanizmov za sesanje in odstranjevanje prahu. Ta evropski standard ne velja za nevarnosti, ki izvirajo iz predelave materialov (npr. azbesta, kliničnih odpadkov, vsebnikov za aerosole). Ta evropski standard ne zajema nevarnosti, ki izvirajo iz namestitve stiskalnic bal na mestih, dostopnih javnosti. Vse nevarnosti, navedene v točki 4, so obravnavane v tem evropskem standardu. Ta evropski standard se ne uporablja za vodoravno delujoče stiskalnice bal, ki so bile izdelane, preden je bil objavljen kot standard EN.
