As shown in fig. 1, 2 and 3, the integrated gantry crane includes: a rail including a rail unit 11; at least two trolleys 21, wherein two opposite side edges of each trolley 21 are movably connected with one track single body 11 respectively, and the number of the trolleys 21 is half of that of the track single bodies 11; and a gantry support assembly, the gantry support assembly comprising: the main beam single bodies 31 are provided with the track single bodies 11, and the number of the track single bodies 11 arranged on each main beam single body 31 is one; and two leg assemblies connected to the main beam single body 31, and supporting one main beam single body 31.

Specifically, the track single body 11 refers to a section of steel rail which is not the crane steel rail according to the recommended standard YB/T5055-1993 in the ferrous metallurgy industry of China, and is 9m or 9.5m or 10m or 10.5m or 11m or 11.5m or 12m or 12.5 m.

Specifically, the descending from bottom to top does not mean that the distance between the two leg bodies 41 decreases at every distance from bottom to top at any position in the height direction. That is, the distance between the two leg bodies 41 does not increase in the bottom-up direction, and the distance between the two leg bodies 41 facing each other is reduced in the bottom-up direction in the partial region of the two leg bodies 41.

Specifically, in this implementation, the leg assembly is perpendicular to the main beam monomer 31 as viewed from above.
