PROBLEM TO BE SOLVED: To provide a non-interference control device mounted to a crane itself to independently avoid interference with the other crane. SOLUTION: A distance between the own crane 1 and the other crane 2 is measured by a crane-to-crane range finder 131 mounted to the own crane 1, and when the crane-to-crane distance is a prescribed slowdown distance or less, a slowdown command is outputted to the own crane. When the self- slowdown of the own crane is confirmed, creep travel is continued until reaching a To point provided from a process computer 3. The prescribed distance is determined according to the relative travel direction of the own crane and other crane, and non-interference control is performed as override control to a control command outputted from an automatic control panel 11.
