How do you raise large artifacts?

Say, an old anchor.. Some sort of inflatable airbag, right?
What search terms should I be using to find info about these airbags and learn more about them?

Thanks.

Check out a few of the anchors and propellers we salvaged over the years. Used subsalve 2000 and 6000 pound bags for most.

Call Richard (owner) at SubSalve. He's got a great overstock/specials list. Great bags at good prices.

Ricky sold good bags, and may well still sell them, if you really want to know how to lift something pm me , no bs I lift daily, ships, barges, boats I lift....so a ... Carter bags ...Pro lift ... a concrete sack with roof paint on the inside so when you rip it you don't lose 500 $$$ a good bag for lifting doing what you are doing.... go with a pillow bag NOT an open end (unless you stick with the concrete bag) then Carter, Prolift, Subsalve boils down to shipping and the quick disconnect. If you go Parachute make sure you can lift it on deck ... good luck.
