We've seen that crane aboard 052D in the past. It's for loading the VLS, and it's not new.
It also isn't a permanent fixture on the ship, but rather something that is emplaced atop the ship (that is to say, it's not like the Mk-41 reloading crane in early Mk-41s where they are folded and enclosed within multiple VLS canister equivalent spaces below deck).
I'll see if I can find some pictures, but they were fairly obvious from back in the day.
Edit:
Found them, courtesy of Henri K's old website, I strongly recommend have a read of it
