Abstract

A lifting lug is installed at an outer plate (1) of a ship body. The lifting lug comprises a main force-receiving plate (100). A plurality of lifting holes (200) are arranged at the main force-receiving plate (100). The main force-receiving plate (100) has a first side (110) and a second side (120) which are parallel to each other. The first side (110) is welded to the outer plate (1) of the ship body. A length of the first side (110) extends in a length direction of the ship body. The lifting lug does not have a panel, and is directly welded to the outer plate (1) of the ship body. Moreover, the lifting lug has a length direction the same as the length direction of the ship body, and thus presents very little resistance in operations of the ship body. Accordingly, the lifting lug can be installed as a permanent lifting lug. There is no need to remove the lifting lug after a rudder blade or a paddle is lifted into position, thereby saving the time required for removal of the lifting lug, reducing costs, and improving performance. Arrangement of the plurality of lifting holes (200) at the lifting lug enables the lifting lug to be applied in many situations. Compared with the prior art, the invention reduces the number of lifting lugs to be installed.
