Naprave za kontinuirni transport - Varnost tračnih transporterjev za zimske športe ali turistične namene

Ta evropski standard velja za tekoče trakove za uporabo v prostem času ali pri zimskih športih. Te zahteve veljajo za tekoče trakove za prevoz potnikov, ki imajo nataknjene pripomočke za drsenje po snegu, ali pešcev, ki imajo obute smučarske čevlje ali težke čevlje in morda nosijo svoje pripomočke za drsenje po snegu za zimskošportne dejavnosti. Pri drugih uporabah morajo uporabniki na transportnih trakovih nositi primerno (zaprto in trdno) obutev. Ta evropski standard je pripravljen na osnovi avtomatskega delovanja teh inštalacij, kjer na mestu dejanske namestitve ni stalno prisotnega osebja. Zajema zahteve v zvezi s preprečevanjem nesreč in varnostjo delavcev. Ta evropski standard obravnava vse velike nevarnosti, nevarne situacije in dogodke, ki se nanašajo na transportne trakove za dejavnosti v prostem času in zimskih športih, kadar se uporabljajo kot predvideno in pod pogoji napačne uporabe, ki jih razumno predvidi proizvajalec (glej točko 4).
