Abstract (en)
A crane includes a horizontal transport device horizontally movable with a motor, a hoisting device mounted on the horizontal transport device, the hoisting device being capable of winding a rope with a hoist motor, a hook attached on the rope to hang a payload and a control unit including a processor and a memory, the control unit being configured to control the horizontal transport device and the hoisting device. The control unit includes a rope tension determination unit configured to determine whether the rope is in a taut state without a slack; a state measurement unit configured to measure at least one state value of the crane when the rope has been wound up into a taut state by the hoisting device being driven and a transport control unit configured to move the horizontal transport device.
