Triceps Press.

The elbow works. The rest stays still.

Cable pushdowns usually end with you putting your upper body into it and leaning over the bar to press out the last few. The back pad here keeps you upright, so the press comes from the elbow alone and the set ends when the triceps are empty. 90 kg in the stack gives you room to go heavy on an exercise people usually treat as a way to finish the session. The machine takes only 1195 × 1130 mm and weighs 208 kg. Under one and a half square metres. The whole back of the arm.
