Looking at several real world cranes, I have noticed that virtually all of them have hooks that can rotate independently of the pulleys, as in the pulley piece that is connected to the lifting cable stays in place, while the hook that the load is attached to can rotate. I'm thinking that a possible reason for this is to allow the road to be rotated while it is suspended from the crane, or possibly to prevent the hoist line from twisting if the load catches the wind. Now, do you guys think that this feature is needed for Lego cranes, or is it just a a cool add on for the model? I have made a model with a hook that rotates, and it is not very helpful, as the hoist lines twist long before the hook moves. In addition, my rotating hook uses a small turntable in order to do that, which has the potential to come apart if the load were large enough. The only other way that I can think of to make a hook rotate is with some threaded axles, but those could break under load. So, what do you guys think? Required feature, or nice add on?
