The invention provides a quay crane mobile power supply device and a power supply method. A cart cable reel motor drives a cart cable reel to rotate, a lifting appliance cable reel motor drives a lifting appliance cable reel to rotate, and a festoon motor drives an electric festoon to move; a cart cable is wound on the cart cable reel, a sling cable is wound on the sling cable reel, and the electric festoon is connected with a festoon cable; the mobile power supply control cabinet sends instructions to the cart cable reel motor, the sling cable reel motor and the festoon motor; the cart cable reel motor and the sling cable reel motor do not work at the same time and share the main frequency converter, so that main control parts are saved; and the size and the cost are reduced.
