"All right. I'm not counting to three." Kuvira makes very sure of her bending grip. She's not strong enough to do a stunt like this without metalbending.

She spools him back down a short ways and starts to swing him to build up momentum and make this a little bit easier, flicking and pressuring the dark, heavily textured metal to enhance the swing until she hits the right point. From there she stiffens part of her cable and puts more into the swing until it's an arc - right over her head, past the opening.

Once he's let go she can get to the much simpler work of getting herself up there, using her cables like very long arms.
