The invention discloses a movable trestle which comprises a trestle body, steel cables, an eye plate, a hanging bracket, a lifting winch, a guide rail and a displacement winch. The trestle body is hinged to the hanging bracket through the eye plate. The rail and the displacement winch are fixedly installed on a deck perpendicular to a ship board and are connected through the steel cables. The lifting winch is installed on a bottom frame of the hanging bracket, the steel cables wound around the lifting winch are directly connected with pulleys on the two sides of the middle of the trestle body through a pulley system installed on the hanging bracket, and therefore a vertical swing structure of the trestle body with the eye plate as a hinging point is formed. The hanging bracket is dragged by the displacement winch through the wound steel cables to reciprocate along the rail. The trestle body is in a flatly-placed state, can be moved to the inner side of the ship board along with the hanging bracket so as to be in a hidden state and can be in an erected state when moved reversely. The movable trestle is prepared for a ship and can be autonomously erected when the ship is moored at a wharf.
