1 Scope
This part of ISO 11662 applies to mobile construction-type lifting cranes utilizing
-
a) rope supported, lattice boom attachment or lattice boom, and fly jib attachment (see Annex E, Figure E.3),
-
b) rope supported, mast attachment and mast mounted boom, and fly jib attachment (see Annex E, Figures E.1 and E.2), or
-
c) telescoping boom attachment or telescopic boom and fly jib attachment (see Figure E.4).
Mobile crane manufacturers can use this part of ISO 11662 to verify their design for the mobile crane types illustrated in Figures E.1 through E.4.
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.
