The invention relates to a samson post type offshore platform crane anti-back-tipping device which comprises two L-shaped anti-back-tipping supports, wherein the two L-shaped anti-back-tipping supports are symmetrically arranged on two opposite sides of a middle body which is connected with a Samson post of a samson post type offshore platform crane through a bearing in a rotating manner, the middle body is welded between a truss of a gantry and a pulley block support, a buffering rubber block with a groove is arranged on the front end of the anti-back-tipping support, the included angle of the front end surface of the buffering rubber block and the horizontal plane is 82 degrees. The samson post type offshore platform crane anti-back-tipping device not only can prevent the samson post type offshore platform crane from tipping back during amplitude variation and solve the rigid impact problem between a suspension arm boom and a Samson post, but also can generate certain limiting role on the suspension arm boo
