[Actually, I don't see much bend in this one.]
Larry Winchester Jibs are for height, not radius.
Keith Havard Hope the pic of boom flexed is with load on hook.
Mike Newcomb lot of cable. [I wonder how much weight the cable itself adds to the load at the end of the boom.]
Mark Walker I'm thinking he maybe close to the end of the chart in that second pic looking from the rear
But the operator needs to know the chart and avoid bending too much. It looks like they should have lifted the tower crane boom as two pieces. Note that as soon as the boom broke, the base lost its load, and it straightened right up.

Here's a great example of collaboration - Cropac Equipment Inc., C&C Crane, Total Crane Rental, and MTN Forming brought their expertise together on this Ontario waterfront project with Terex SK 315 and SK 415 tower cranes http://info.terex.com/OntarioTowers
[It looks like there is a bend in that boom to me. It also looks like the inner segments are only partially extended. I assume they are overlapping more steel at the base of the boom to try to reduce the bend.]

[Each segment is extended the same amount, but only about 2/3 of its length. I think there is a little bend in the boom.]
