标准范围

本文件根据使用条件对移动式起重机和相关起重机机构进行了一般分类，主要表现为:-在起重机的规定设计寿命内进行的工作循环总数；-荷载谱系数，代表待处理荷载的相对频率；-平均荷载位移。本文件适用于表2所述的中等至极大量工作循环之间的工作范围。

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.
