riggers for lifting big stuff,
Construction crane,
your engine has about 20 of them (all the little wheels that touch the belt)
Hydro dams, have giant water wheels which are connected to belts which are connected to turbines

Tension springs for garage doors have two pulleys on each side of the door. Click on the source link I posted below for an illustration. Some older outdoor flagpoles have a two pulley system. One pulley is located at the top of the mast and the other pulley is near the other end. I could not find an illustration for this.

How about a large crane with counter weights, telescoping and angling booms, several pulleys, and tag lines all computerized.

Flagpoles. Do they have to be man-powered? I think elevators qualify as pulley systems, but one generally doesn't power one by hand.
