A jig is provided for holding the workpiece having a pair of suspending points at each end thereof in symmetrical relationship about a horizontal axial line. Ropes suspend the jig with each one connected to one of the suspending points at each end of said jig. In a first embodiment, a pair of hoisting apparatuses are provided with upper ends of the ropes connected to suspending points on one side at both ends of the jig being connected to one of the hoisting apparatuses and upper ends of the ropes connected to suspending points on the other side at both ends of the jig being connected to the other of the hoisting apparatuses. In a second embodiment, a pair of jig-rotating wheels are fixed on the same horizontal axial line at both ends of the jig. The ropes for suspending the jig are respectively wound around the jig-rotating wheels. A pair of hoisting apparatuses are provided with one end of each of the ropes being connected to one of the hoisting apparatuses and the other end of each of the ropes being connected to the other of the hoisting apparatuses.
