标准摘要
[中文适用范围]： 本文件根据使用条件对移动式起重机及相关起重机机构进行了一般分类，主要表现为： ——起重机在规定设计寿命期间所进行的工作循环总数； ——负载谱因子，代表待处理负载的相对频率； ——平均载荷位移。 本文件适用于中等到大量工作循环之间的工作范围，如表 2 中所述。 [外文原描述]： This document establishes a general classification of mobile cranes and related crane mechanisms based on the service conditions, mainly expressed by the following: — the total number of working cycles to be carried out during the specified design life of the crane; — the load spectrum factor which represents the relative frequencies of loads to be handled; — the average load displacements. This document is applicable for the work spectrum between moderate to very heavy number of work cycles as described in Table 2.
