27、s standard has been prepared to be a harmonised standard to provide one means of conforming with the essential safety requirements of the Machinery 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 w
28、hich hazards, hazardous situations and events are covered are indicated in the scope of this standard. When provisions of this type C standard are 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 s
29、tandards, for machines that have been designed and built according to the provisions of this type C standard. With the aim of clarifying the intention of the standard and avoiding doubts when reading it, the following assumptions were made when producing it : -only competent persons operate the mach
30、ine -components without specific requirements are designed in accordance with usual engineering practice and calculation code, including all failure modes. 1Scope 1.1This standard applies to pallet trucks as defined in 3.1 with lift heights up to 300 mm and rated capacities up to and including 2 000
31、 kg, hereinafter referred to as “trucks“. 1.2Attachments, fixed or removable, which can be installed on the truck are not dealt with in this standard. 1.3This standard deals with the technical requirements to minimise the hazards listed in clause 4 which can arise during commissioning, operation and
32、 maintenance of trucks when carried out in accordance with the specifications as intended by the manufacturer or his authorised representative. In addition trucks shall comply, for the hazards not covered by this standard, with the applicable companion standards and as appropriate with EN 292. 1.4Th
33、is 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 magnetic fields), -operation subject to special rules (e.g. potentially explosive a
34、tmospheres), -handling of loads the nature of which could lead to dangerous situations (e.g. molten metal, acids/alcalies, radiating materials, specially brittle loads), -hazards occurring during construction, transportation, decommissioning and disposal, -direct contact trucks with foodstuffs, -ope
35、ration on gradients or on surfaces other than smooth, level, hard surfaces, -trucks with powered lifting. 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 to static electricity are not
36、dealt with in this standard. 1.7This standard applies to trucks manufactured after the date of issue.
