When performing the conveyance from an arbitrary cargo start position to an arbitrary cargo target position, it is possible to control swing prevention without constraint condition and with a simple control system. There is provided a cargo crane including an arm turning mechanism (4) that turns a crane arm (2); an arm luffing mechanism (3) that adjusts the luffing angle; an arm extension and contraction mechanism (5) that adjusts the arm length; and a control device that calculates a trajectory in which a suspended cargo (7) is conveyed, and that controls the arm turning mechanism (4), the arm luffing mechanism (3), and the arm extension and contraction mechanism (5). The control device calculates the trajectory so as to be a straight line trajectory as viewed from at least the vertical direction, according to the cargo start position and the cargo target position; calculates a turning angle θ, a luffing angle ϕ, and an arm length L so as to cause the trajectory to be the straight line trajectory by using the cargo start position, the cargo target position, a maximum speed vmax, a suspended cargo swing cycle T, and a start-up time T1; and controls the arm turning mechanism (4), the arm luffing mechanism (3), and the arm extension and contraction mechanism (5) so as to achieve the calculated turning angle θ, luffing angle ϕ, and arm length L.
