    • A hoisting device can be small-sized and energy can be saved. A hoisting device 10 according to the present invention has a hoist 30 and a control unit 32. The hoist 30 rotates a drum 12 having a wire 14 wound thereon by an oil pressure motor 42 rotatable in normal and reverse directions. To the oil pressure motor 42, operating oil is supplied from an oil pressure pump 44. The oil pressure pump 44 is a two-way discharge fixed capacity type, and rotated by a servomotor 46. An acceleration/displacement transducer 34 in the control unit 32 finds a moving direction and a moving speed of a wire hanging point in the vertical direction from an output signal of an acceleration sensor 24. The control unit 32 outputs a drive control signal of the servomotor 46 according to a paying-out speed or a rolling-up speed of the wire 14 offsetting the vertical motion of the wire hanging point caused by the heaving of a hull based on a speed instruction Vi of the paying-out or rolling-up speed of the wire, a detected signal of the acceleration sensor 24 and a detected signal of a wire speed sensor 26.
