PROBLEM TO BE SOLVED: To provide a power supplying device for mobile crane device for both AC and DC allowing the use of AC power supply in case of emergency using a versatile inverter commercially available without risk of being influenced by the conductors, etc., leading from the power supply even in the trackless region. SOLUTION: This power supplying device 1 is composed of a battery 2 and inverter 3 and installed on a mobile crane 4, wherein the areas between the front legs 5a and rear legs on both sides are made in two stages, and the battery 2 is mounted, and a plurality of the inverters 3 are installed inside a control board 16 provided between the front legs 5a, and a wind-up motor 9 and a traversing motor 10 are connected with a running motor 11 through the inverter 3. By this simple structure in which the battery 2 and inverter 3 are connected with a working motor of mobile type crane device, there is no need to use conductors, etc., leading from the external power supply, so that the mobile crane device can be moved over a wide trackless region, and it is possible to smoothly transport the component parts.
