English to Italian Tech/Engineering Mechanics / Mech Engineering

the subject is Steam Turbines:

Trunnions are the typical lifting provisions used for handling (e.g., lifting, flipping) shells during machining, assembly and maintenance.
The location and size of the trunnions depends on the weight, size, Center of Gravity (CG) location, accessibility and complexity of the component to be lifted.
Other lifting provisions (on the shell) include trunnions with threaded holes for swivel hoist rings, ***lifting bales*** and (rarely) lifting eyes or holes for eyebolts.

Thanks a lot!
