[0030] Example 2

[0031] Based on Example 1, a preferred embodiment of a lightweight base for a marine crane provided by the utility model is as follows: Figures 1 to 5 As shown: the springs 303 are evenly distributed on the outer wall of the mounting plate 301, and the protective plate 304 forms a telescopic structure with the mounting plate 301 through the springs 303.
