EN 474的这一部分涉及到符合EN ISO 6165:2006所定义的电缆挖掘机相关的所有重大危险，危险情况和事件，如果按照预期和在制造商合理预见的误用条件下使用（见第4条）。 本欧洲标准也适用于电缆挖掘机，起落架和上部结构，如果打算与其他设备或附件结合使用，例如钻机，打桩和提取设备和移动设备（例如铁路轨道，步行腿，浮桥，船舶）或固定起落架。本欧洲标准不涉及由于这些附加设备或附件造成的特定危险。 注意对于这些附加设备或附件，应考虑相关的具体欧洲标准，例如: - 用于打桩和提取设备:EN 996:1995; - 用于钻机:EN 791:1995。 本部分的要求与EN 474-1:2006中制定的共同要求相辅相成。 本部分不重复EN 474-1:2006的要求，但增加或取代了电缆挖掘机的应用要求。 本部分规定了消除或减少有意义的风险的适当技术措施

This part of EN 474 deals with all significant hazards, hazardous situations and events relevant to cable excavators as defined in EN ISO 6165:2006, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4). This European Standard applies also to cable excavators, their undercarriage and upper-structure, if intended for use in combination with other equipment or attachment, such as drill rigs, pile driving and extracting equipment and moving equipment (e.g. rail track, walking legs, pontoon, ship) or stationary undercarriage. This European Standard is not dealing with the specific hazards due to these additional equipment or attachment. NOTE For these additional equipment or attachment, relevant specific European Standards should be considered where available, for example: - for pile driving and extracting equipment: EN 996:1995; - for drill rigs: EN 791:1995. The requirements of this part are complementarily to the common requirements formulated in EN 474-1:2006. This part does not repeat the requirements from EN 474-1:2006, but adds or replaces the requirements for application for cable excavators. This part specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazards, hazardous situations and events during commissioning, operation and maintenance of the machinery in the scope. This European Standard is not applicable to cable excavators manufactured before the date of publication of this European Standard by CEN.
