34、Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Slovakia, Spain, Sweden, Switzerland and the United Kingdom. 0Introduction This standard has been prepared to be a harmonised standard to provide one means of conforming with the essential safety requirements of the Machinery
35、 Directive and associated EFTA Regulations. This European standard is a type C standard as stated in EN 1070. The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the scope of this standard. When provisions of this type C standard are
36、different 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 according to the provisions of this type C standard. With the aim of clarifying the intent
37、ion of the standard and avoiding doubts when reading it, the following assumptions were made when producing it : -only competent persons operate the machine -components without specific requirements are designed in accordance with usual engineering practice and calculation code, including all failur
38、e modes. 1Scope 1.1 This standard applies to pedestrian propelled industrial scissor lift pallet trucks as defined in 3.1 with lift heights up to 1,000 mm and rated capacities up to and including 1,000 kg hereinafter referred to as “trucks“. On board battery chargers are part of the truck. 1.2 Attac
39、hments, fixed or removable, which can be installed on the truck are not dealt with in this standard. The lifting tables referred to in EN 1570 are not dealt with in this standard. 1.3 This standard deals with the technical requirements to minimise the hazards listed in clause 4 which can arise durin
40、g commissioning, operation and maintenance of trucks when carried out in accordance with the specifications as intended by the manufacturer. In addition trucks should comply, for the hazards not covered by this standard, with the applicable companion standards and as appropriate with EN 292. License

EN 1757-4:2003 (E) 6 1.4This standard does not establish the additional requirements for : -operation in severe conditions (e.g. extreme environmental conditions such as : freezer applications, high temperatures, corrosive environment, strong magn
42、etic fields), -operation subject to special rules (e.g. potentially explosive atmospheres), -electromagnetic compatibility (emission - immunity), -handling of loads the nature of which could lead to dangerous situations (e.g. molten metal, acids/alkalis, radiating materials, specially brittle loads)
43、, -hazards occurring during construction, transportation, decommissioning and disposal, -wind pressure in and out of use, -direct contact with foodstuffs, -operation on surface other than smooth, level, hard surfaces or gradients, -lifting of persons, -trucks whose lifting is powered by external mea
44、ns : electrical (mains .), pneumatic source, . 1.5Other possible limitations of the scope of other standards referred to that also apply to this standard. 1.6Hazards relevant to noise, vibration, visibility and static electricity are not dealt with in this standard. 1.7This standard applies to truck
45、s manufactured after the date of issue. 2Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text, and the publications are listed hereafter. For dated refere
