Procedure 10-4 Lifting Loads and Forces

Overall load factor, Ki. Kl = Ki + Ks Design lift weight, Wi,. Wl = KlWe Tailing load, T. 

Lift angles shown are suggested only to help find the worst case for loads T and P. 

Radial loads in shell due to sling angles, 6y or Oh. Pr = Pt tan % Vessel in horizontal 

Maximum moment occurs at initial pick, when 6 = 0. See cases 1 through 4 for maximum moment, M. 

If the tailing point is below the CG as is the case when a tailing frame or sled is used, the tail support could see the entire weight of the vessel as erection approaches 90°.
