Heavy tower crane for lifting construction of heavy steel structure corridor

The utility model discloses a heavy tower crane for lifting construction of a heavy steel structure corridor, and relates to the technical field of heavy tower cranes, the heavy tower crane comprises a base, the top of the base is fixedly connected with a tower body, the top of the tower body is rotatably connected with a transportation plate, and the top of the base is provided with a protection mechanism on one side of the tower body. In order to avoid potential safety hazards caused by the fact that the tower body slightly swings for a long time, when the tower body slightly swings, thrust is applied to the transmission plate, the transmission rod moves towards the side face along with the transmission plate, due to the fact that the transmission rod is embedded into the inclined groove of the stress block, when the transmission rod moves left and right, thrust is applied to the stress block through the inclined groove in the stress block, and therefore the transmission rod cannot move towards the side fac
