The invention discloses a suspension arm structure, an offshore crane and a hoisting method, the suspension arm structure comprises a propeller strut mounted on a rotary table, a vertical rod and an inclined strut, one end of the inclined strut is connected with the top end of the propeller strut, the other end of the inclined strut is connected with the top end of the vertical rod, and the bottom end of the vertical rod is connected with the bottom end of the propeller strut; the near end of the main arm connecting rod is rotationally connected to the joint of the propeller strut and the inclined strut, and the far end of the main arm connecting rod is hinged to the near end of the main arm. The far end of the main arm and the far end of the main arm connecting rod are both connected with transmission mechanisms so as to drive the main arm to rotate around the hinge point of the main arm and the main arm connecting rod to rotate around the hinge point of the main arm. Compared with equipment with the same deck projection area, the lifting height can be increased by about 50 m; the suspension arm structure can be directly mounted on a ship in service without upgrading the ship in service.

    本发明公开了一种吊臂结构、海上起重机及起吊方法,吊臂结构包括安装在转台上的人字架,还包括立杆和斜撑,斜撑的一端和人字架的顶端相连接,斜撑的另一端和立杆的顶端相连接,立杆的底端和人字架的底端相连接;主臂连接杆的近端转动连接在人字架和斜撑的连接处,远端和主臂的近端铰接连接;主臂的远端和主臂连接杆的远端均连接有传动机构,以带动主臂绕其铰接点转动及主臂连接杆绕其铰点转动。本申请提升高度相对于同等甲板投影面积的设备可提升50m左右;使用该吊臂结构,无需升级现役船体,可将其直接安装在现役船上。
