本SAE标准适用于悬臂臂式移动式建筑起重机。有关本试验方法中规定的应用或解释的问题和意见应提交给原始SAE委员会。本试验方法的目的是提供一个系统的、非破坏性的程序，通过使用电阻式电子应变计，在规定的静载荷条件下，测定悬臂起重机结构中产生的应力，并为规定的载荷条件规定适当的应力水平。 此外，还包括25%的过载试验，以证明结构的整体结构完整性。

This SAE Standard applies to mobile, construction-type lifting cranes of the cantilever boom type. Questions and comments regarding application or interpretation of the provisions in this test method should be referred to the originating SAE Committee.The purpose of this test method is to provide a systematic, nondestructive procedure for determining the stresses induced in cantilevered boom crane structures under specified conditions of static loading through use of resistance-type electric strain gages, and to specify appropriate stress levels for specified loading conditions. Further, a 25% overload test is included to prove the overall structural integrity of the structure.
