Thus, features defined as "first", "second", may explicitly or implicitly include one or more of the described features. In the description of the present invention, "a plurality" means two or more unless specifically limited otherwise. Furthermore, the terms "mounted," "connected," and "connected" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1-2, the utility model provides a overhead crane on offshore wind turbine tower, include:

the bottom of the frame 1 is provided with a bottom plate 5; the parts to be handled are placed on the floor 5 of the frame 1.

The lifting device 10 is arranged at the top of the frame 1; the trolley 10 is a chain block. The frame 1 is lifted by the hoist 10.

Baffle 3 sets up in the side of frame 1, and baffle 3 can reciprocate, and baffle 3 is used for blocking the part of placing in the frame 1, prevents that the part from dropping, can upwards move baffle 3 when placing the part, just so need not lift up the part and put into frame 1 in the top of baffle 3, conveniently places also the physical power of saving porter.

The frame 1 is a rectangular frame, and the four side surfaces of the rectangular frame are provided with baffle plates 3.
