Description / Abstract:
This SAE Standard applies to mobile, construction-type lifting
cranes of the cantilever boom type (Figure 1). Questions and
comments regarding application or interpretation of the provisions
in this test method should be referred to the originating SAE
Committee.1
Purpose
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.
