Parking attachments work great, that said on our K&T K-2's we built swing arm jib cranes above both as we have more then one attachment for them and then we store them on a heavy rolling table. Easley roll up along side the machine and lift the attachment up and slide it on. Great for sharing attachments between machines as well. All our K&T attachments have lift points at the center of gravity, we simply built small D rings and threaded them into the factory lifting points.
The other great benefit of this is the jib is used to load/unload heavy material on the mills table.
