Lat Pulldown.

The lats move in an arc. The bar does not.

A straight bar forces the elbows into a path that is a compromise between two shoulders, and you usually feel it in the shoulder long before you feel it in the back. The pulling path here follows the arc the lats actually work in, from a full stretch overhead to the elbows along the sides. The thigh pad presses you down into the seat so you cannot rise with the pull, and plate loading (Ø50 mm) lets you add weight in small steps. The frame is 1880 mm high, measure the ceiling, takes 1560 × 1530 mm of floor and weighs 145 kg. The back decides the path. Not the bar.
