PROBLEM TO BE SOLVED: To provide a tuning device of crane equipment with two crane devices to be used independently, to be operated by one worker when the two crane devices are used for carrying a long article, etc., capable of carrying the article efficiently and safely. SOLUTION: The tuning device is for the crane equipment comprising girders 4 and 8 made to travel by traveling motors 15 and 19, crab trolleys 5 and 9 made to travel by traversing motors 22 and 28, and wires 6 and 10 hanging from the crab trolleys 5 and 9. The tuning device freely selects the operation condition from the single operation to the tuned operation. In the single operation, the traveling motor 12 and the traversing motor 22 of a first crane device 2, and the traveling motor 19 and the traversing motor 28 of a second crane device 3 are independently driven. In the tuned operation, the traveling motors 15 and 19 of the two crane devices 2 and 3 are tuned to be driven, and the traversing motors 22 and 28 of both crane devices 2 and 3 are also tuned to be driven.
