Figure 1 As shown, when the four-link gantry crane 300 is transported by sea, a whole piece of cement counterweight will be poured behind the turntable 320. When the gantry crane 300 is subjected to the ship acceleration caused by waves during the sea transportation, the mass concentrated at the tail of the turntable 320 will cause a large bending moment on the root of the cylinder 310, and the force is concentrated. Therefore, the lashing of the whole gantry crane 300 is mainly for the cylinder 310.

[0043] When the gantry crane 300 is transported by sea, multiple groups of cable assemblies 100 need to be arranged and cooperate with each other. In the embodiment of the utility model, only one group of cable assemblies 100 is described.

[0044] The following describes in detail the marine cable assembly 100 of the gantry crane 300 according to the embodiment of the utility model with reference to the accompanying drawings.
