This test method is to provide a systematic, non-destructive procedure for determining the stresses induced in crane structures under specified conditions of static loading through the use of resistance-type electric strain gauges, and to specify appropriate acceptance criteria for specified loading conditions.
ISO 11662-2:2014 applies to mobile construction-type lifting cranes utilizing
a) rope-supported, lattice boom attachment or lattice boom, and fly jib attachment,
b) rope-supported, mast attachment and mast-mounted boom, and fly jib attachment, or
c) telescoping boom attachment or telescopic boom and fly jib attachment.
Mobile crane manufacturers can use ISO 11662-2:2014 to verify their design for the mobile crane types illustrated in its Annex E.
