Here this is the file but I do not know how to fix the loft problem if anyone can do it and send me the completed lofted crane hook I will be more then thankful to him.

There where problems with intersections. Here is Quick and dirty fix. I suggest that You draw both rails (sketch1 and 11) again with splines to be sure that Your Coincident Constraint work precise.

As Leo wrote, there is a problem with intersections. I think that you should try to redesign sketches: first you need to sketch sections of the hook and then do "Project Geometry" and connect all drawn sections with the rails of the hook.

I usually try the lock constraint when lofting, give it Shot
