not at all...Note in the page ref, example #2 where running load is exceeded.
I also explained several posts back as to when you start looking at concentrated loads, and when you look at the height of the load.
The contact load portion you ref is not applicable to the OP. Contact loading assumes there are no spreaders, it is the direct contact point of the object. The OP specifically ref spreaders.
and speaking quoting only one page...
You quote page 221, note the next page, 222. Contact load with spreaders and without. Note the surface area used with the spreaders.
