[0021] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0023] like Figures 1-7 As shown, the temporary rail system for the overall transport of gantry cranes with different gauges on the dock includes lifting lugs 1, winches 2, and temporary rails 3. A pair of lifting lugs 1 are set on both sides of the gantry crane 4's frame 5. The hub below the gantry 5 is equipped with a transfer wheel 6 at a vertical 90° angle. The temporary rails 3 are laid on land and on the ship respectively and fit with the transfer wheel 6. A locking mechanism is provided at the joint of the two sections of temporary rails 3. A pair of winches 2 are set on the ship 7, and the wire rope 8 on the winch 2 is connected to the lifting lugs 1.
