Embodiment
[0032] Such as Figure 1 to Figure 4 As shown, this embodiment provides a differential rail container crane, which includes: a mast structure 1 , a trolley 3 and a driving mechanism for driving the trolley to travel on the top of the mast mechanism 1 .
[0033] Wherein, the portal frame structure 1 includes a load-bearing main beam 2 and two support frames 5 for supporting the load-bearing main beam 2 . The load-bearing main girder is a triangular tube structure single main girder and its node form is a contained node. The parameters of the single main girder of the triangular tube structure are as follows: the main chord is φ400×12, the web is φ159×10, the span is 31m, the height is 3 meters, and the section moment of inertia is 0.9×1011mm 4 , the weight per unit length including the track is 0.7 tons, and it can withstand a lifting load of 50 tons. It is the lightest product of the same type in the world. The nodes carrying the main girder adopt inclusive nodes, which grea...
