Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held respons

19、ible for identifying any or all such patent rights. This document supersedes EN 1755:2000+A2:2013. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For relationship

20、 with EU Directive(s), see informative Annex ZA, which is an integral part of this document. Informative Annex F provides details of significant technical changes between this document and the previous edition: EN 1755:2000+A2:2013. This document is one of a series of European Standards for the safe

21、ty of industrial trucks which are listed in 4.1 and in the Bibliography. According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denm

23、5EN 1755:2015 (E) 4 Introduction This standard is a type-C standard as stated in EN ISO 12100. The machinery concerned and the extent to which hazards, hazardous situations and hazardous events are covered, are indicated in the scope of this standard. When provisions of this type C standard are diff

24、erent from those which are stated in type A or B standards, the provisions of this type C standard take precedence over the provisions of the other standards for machines that have been designed and built in accordance with the provisions of this type C standard. This standard (EN 1755:2015) covers

25、safety requirements and their verification for industrial trucks as defined in ISO 5053-1 that are not covered exhaustively by: EN 1459; EN 1526; EN 1757-3; EN ISO 3691-1; EN ISO 3691-5; EN ISO 3691-6; NOTE The above-mentioned standards are listed in the Bibliography or in Clause 2. Assessment of ha

26、zards The industrial truck needs to be designed in such a way that it is fit for its purpose or function and can be adjusted and maintained without putting persons at risk when used under the conditions foreseen (e.g. explosive atmospheres) by the manufacturer. In order to properly design an industr

27、ial truck and to cover all specific safety requirements, the manufacturer will have to identify the hazards that apply to the industrial truck and carry out a risk assessment. The manufacturer will then need to design and construct the industrial truck taking this assessment into account. The aim of

28、 this procedure is to eliminate the risk of accidents throughout the foreseeable lifetime of the machinery, including the phases of assembling and dismantling where risks of accidents could also arise from foreseeable abnormal situations. In selecting the most appropriate methods, the manufacturer w

29、ill need to apply the following principles, in the order given here: eliminate or reduce risks as far as possible by design (inherently safe machinery design and construction); take the necessary protective measures in relation to risks that cannot be eliminated by design; inform users of any shortc

30、oming of the protective measures adopted; indicate whether any particular training is required; specify any need to provide personal protection equipment; refer to the appropriate users document for proper operating instructions. BS EN 1755:2015EN 1755:2015 (E) 5 Industrial trucks need to be designe

31、d to prevent foreseeable misuse wherever possible, if such would engender risk. In other cases, the instructions will need to draw the users attention to ways shown by experience in which the machinery ought not to be used. This standard (EN 1755:2015) does not repeat all the technical rules which a

32、re state-of-the art and which are applicable to the material used to construct the industrial truck. Reference will also need to be made to EN ISO 12100. BS EN 1755:2015EN 1755:2015 (E) 6 1 Scope This European Standard applies to self-propelled and pedestrian propelled manual and semi-manual industr

33、ial trucks as defined in ISO 5053-1 including their load handling devices and attachments (hereafter referred to as trucks) intended for use in potentially explosive atmospheres. NOTE 1 Attachments mounted on the load carrier or on fork arms which are removable by the user are not considered to be a

34、 part of the truck. This European Standard specifies supplementary technical requirements for the prevention of the ignition of an explosive atmosphere of flammable gases, vapours, mists or dusts by industrial trucks of equipment group II and equipment category 2G, 3G, 2D or 3D. NOTE 2 The relations

35、hip between an equipment category (hereafter referred to as category) and the corresponding zone (area classification) is shown in informative Annex B. This European Standard does not include: trucks of equipment group I; trucks of equipment group II, equipment category 1; trucks intended for use in

36、 potentially explosive atmospheres with hybrid mixtures; protective systems. This European Standard is not applicable to trucks intended for use in potentially explosive atmospheres of carbon disulphide (CS2), carbon monoxide (CO) and/or ethylene oxide (C2H4O) due to the special properties of these

37、gases. This standard is applicable to trucks intended for use in atmospheres with an ambient temperature range of - 20 C to +40 C, i.e. trucks built in accordance with this European Standard will be satisfactory to any service conditions within this range unless otherwise specified. NOTE 3 The ambie

38、nt temperature range -20 C to +40 C is in line with EN ISO 3691-1. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
