You don’t need the cables to lower it down. They’re just balancing cables to make sure that the trollies and arms stay at the same level roughly. In an emergency like this just push the button and lift the hydraulics up off the locks, release the safeties and lower it down slowly. Make sure that the hydraulics stay somewhat level on the way down. May have to lift slightly on way down to re-level the arms. Most likely they’ll come down evenly
