A swinging boom in a shop is customarily called a 'jib boom'. The one shown here is to service a large lathe. Jib booms typically have a carriage on them to allow the chain hoist to travel and of course some sort of a 'chain fall'. Shown here is a 2000 lb imported manual chain hoists. Electric hoists are popular with the users, but also much more expensive. Manual ones are inexpensive and particularly suited for locations where they are infrequently used.
This is a little Jet and it is able to frequently tangle its chain, but it works reliably and is one of the cheaper ones. With chucks and face plates weighing 100 to 500 lbs and possibly more, there is just no way to use a big lathe without a chain fall available. It is needed not only for the chucks, but often the work that is put in a giant lathe needs a chain fall just to position it in the lathe.
Shown in the second photo, we have actually installed 2 jib booms over the American Tool Works Engine Lathe (ATW lathe). The lathe is around 24 feet long counting the headstock (15 feet between centers) and it isn't practical to have one jib reach the entire lathe, so we put up 2 8 foot jibs. The head jib fully reaches over the headstock so it can dismantle the lathe if necessary or take the motor off the top of it.
The tail jib overlaps the head jib by a couple of feet to facilitate hand offs and reaches around 4 feet behind the lathe where incoming things would be if they arrive in the back of a pickup or on a pallet.
In the latter pictures you see a couple of jibs one for another lathe and the one on the right delivers iron to the power band saw for cutting.
