Cantilevered Boom Crane Structures-Method of Test
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.<p>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.
