A gantry is a big, strong frame, usually of steel, that stands over something so heavy kit can hang from it or sit on it. You see gantries over motorways holding the large road signs, over railway lines holding the lights that tell a train to stop or go, and in docks or factories where a crane runs along the top. A rocket may stand inside a launch gantry before it flies.
