SAE J 987
This SAE Standard applies to mobile construction-type lifting cranes utilizing rope-supported, conventional and luffing type lattice boom crane structures.The purpose of this test method is to provide a systematic nondestructive procedure for determining the stresses induced in crane structures under specified conditions of static loading through use of resistance-type electric strain gages, and to specify appropriate acceptance criteria for specified loading conditions.
