Choker Design
(OP)
Dear Colleagues:
I have checked for a Cinch to lift a equipment using 2 of this type. We have checked critical points and we know very well the responsibility of kind of lifting. Problem to me at this point, I try to evaluate using Moss pag 416 (transp and erection ....)but unfortunatelly we will apply another rope angle (57 instead 30 as worked example).
Looking in Roark, Moss indicates a combination valid for 5Th edition (table 17 cases 12 and 18 combined), so I have 6th edition and proposed combination is not applicable. Could you explain me which cases are applicables in 6th edition?
Thanks in advanced
Luike
