I Spy 22 Eyes Down Please.

Technical 

Climbing support collar, cab ? 

Cat head, Counter Jib, Central ballast.

I suspect Googling crane parts won't help  

  So well done in finding all these "C"s but not my one yet, I do hope I have not got this wrong so someone had better get it right soon, 

        Edward has a connection apart from taking the shot, 

 Nope

 I suppose that should read-  yes, Edward's name is Lever

          and then nope 

  re googling crane parts:-

            not so much a part on the crane, more the physics of it.
