Here are a couple more photos. This is the RH wing, looking outboard. The "tool" that I'm responsible for in this particular case is the large beam mounted to the wing. It picks up the forward and aft engine strut mounts. The rest of the stuff, like the big yellow jacks, are all commercial items commonly used in our industry. The trailer underneath belongs to the shipping company we hire to drive it all down the road.
What was "fun" (at least for guys like me) was working with our wing structures guys to come up with a way to apply loads to those strut mounts that they were never designed to receive. No one ever envisioned using them to support the wing (we have dedicated jacking points for that, and we use cradles), much less any kind of side loads to "pull" the wing off the airplane. Fun stuff...
Oh, and here are the cradles, or wooden bucks we normally use to support things when we cannot use the primary jacks. We only use these when there are no for and aft, side, or other loads to consider:
