load distribution using spreaders

[HIGHFLY33]

I have a quick and simple question for you all that is causing somewhat of a dissagrement in our ops department.

The question relates to load distribution calculations whilst using spreaders

concerning floor load limitations , surely the 667 kg/m2 is the correct answer ?

pleease feel free to share your views and thoughts on this matter,

Thank you in advance
