The invention provides a rubber-tired container gantry crane and a steering device thereof. The steering device is characterized in that the device comprises a cart equalizer bar, a left supporting cart frame, a right supporting cart frame, pivoting supports and a push rod which can move in two directions; left wheels are arranged below the left supporting cart frame; right wheels are arranged below the right supporting cart frame; the left supporting cart frame is provided with an area allowing a pin roll connection; the left supporting cart frame and the right supporting cart frame are connected to the cart equalizer bar through the pivoting supports; one end of the push rod is connected to a pin roll of the left supporting cart frame and the other end of the push rod is connected to a pin roll of the right supporting cart frame; and the two ends of the push rod move in the same direction to drive the left supporting cart frame and the right supporting cart frame to rotate in the same direction. The steering device realizes a direction change without a lifting-up structure, does not need a connecting rod and its associated parts, has the advantages of less parts, light quality and compact structure.
