If it’s only a few feet I’d ask around the spot and see if anyone who works in warehouse or somewhere with a loading dock can borrow a j-bar. With an extension plate you could prob walk it one end at time to where you want it in a matter of minutes.
I don’t know who it was or where I saw it, but a few years back some dudes posted a video of some big wooden wheels they made with a negative space cut out of the barrier profile in the middle. They jacked it up, slipped the wheels on like you would wheels on a skateboard truck, and tumbled the barrier across the spot. There’s no way I’m explaining this clearly, and there’s obv simpler ways… but for its own sake, it was a beautiful thing.
