Scope
This SAE Standard applies to mobile construction-type lifting cranes utilizing pendant-supported, conventional, and luffing jib type lattice boom crane structures.
Rationale
Revisions have been made to the following sections:
-
Updated Section 1 from “rope supported” to “pendant supported.”
-
Updated Section 1 from “luffing type” to “luffing jib type.”
-
Updated Table 1 header from “luffing attachment” to “luffing jib.”
-
Updated Table 1 in throughout from “luffing boom” to “boom.”
-
Updated 6.5 from “ASTM 251-67” to “ASTM E251.”
-
Updated Table 1 tests H, K, and N to include offsets for boom top to jib butt and jib sheave to jib centerline.
-
Updated Table 2 test J to include offsets for boom top to jib butt and jib sheave to jib centerline.
-
Updated 8.9 designation for the note was removed from second paragraph because paragraph contained a normative requirement.
-
Updated 9.2.2 Table 1 reference to Table 2 for conventional cranes.
-
Updated 9.2.2.b. equation reference from Equation 7 to Equation 5.
-
Added Figure 3 to 9.2.2 in relation to Table 2 test J update.
-
Added YH and YS to Appendix A in relation to Figure 3.
-
Updated from “must” to “shall” in 5.3, 6.5, 8.9, Appendix B in two locations, and Appendix C in three locations.
-
Updated from “may” to “should” in 4.1 in four locations: 6.6, 7.5, 9.1, 9.2.2, and Appendix C.

* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
