A lifting beam for suspending an object to be lifted in a vertical direction has a lower end surface extending in a longitudinal direction of the lifting beam on a vertical lower side in a state where the object is suspended. The lower end surface includes a first lower end portion, a second lower end portion positioned away from the first lower end portion to a first side in the longitudinal direction, and a third lower end portion positioned away from the first lower end portion to a second side in the longitudinal direction, on the opposite side of the first lower end portion from the second lower end portion. The second lower end portion is positioned higher than the first lower end portion, and the third lower end portion is positioned lower than the second lower end portion when the object is suspended from the lifting beam.
