PROBLEM TO BE SOLVED: To provide a lifter device excellent in working easiness capable of facilitating positioning with an object to be lifted in the plane direction. SOLUTION: The lifter device is equipped with jacks 2 near the four corners of an elevating/sinking frame 1 having approximately a rectangular planar shape and a hang-down device 5 installed at the elevating/sinking frame 1 and is arranged to hang down and support a work W set below the frame 1 by the hang-down device 5, wherein the hang-down device 5 is formed movable in the fore-and-aft direction and width direction of the frame 1. According to this constitution, the positioning of the work W with the hang-down device 5 in the plane direction when the work W is hung down and supported by the hang-down device 5 can be established easily and properly without moving the work W, by moving the hang-down device 5 in the fore-and-aft direction and/or width direction of the frame 1, which enhances greatly the easiness in the hang-down operation of the lifter device.
