A crane (2) comprising a base portion (4), two arms (6, 8) movably connected to the base portion, and a hoisting boom (22) movably connected to the base portion, provided with a hoisting rope (32) and a hoisting member (30), such as a hoisting hook, for hoisting a load, where the two arms and the base portion in combination comprise at least three tower flange connection elements (10) for connecting the tower flange connection elements (10) to the base portion. The tower flange connection elements are arranged to be detachably connected to mating crane connection elements on flanges of wind turbine tower segments, where each arm comprises one of the tower flange connection elements, and where in a normal operating position of the crane, the tower flange connection elements are arranged to be detachably connected to mating crane connection elements on flanges of the wind turbine tower segments, where each arm comprises one of the tower flange connection elements. The vertical distance between any two tower flange connecting elements is less than 1 m, less than 50 cm, or less than 25 cm. In this way, a crane is provided that can be connected to a flange located at an upper portion of a tower segment.

    一种吊机(2),包括底座部分(4)、可移动地连接到底座部分的两个臂(6,8)和可移动地连接到底座部分的起重吊杆(22),所述起重吊杆设置有起重绳索(32)和起重构件(30),例如起重钩,用于提升负载,其中,两个臂和底座部分组合包括至少三个塔架凸缘连接元件(10),所述塔架凸缘连接元件被布置成可拆卸地连接到风力涡轮机塔架节段的凸缘上的相配合的吊机连接元件,其中,每个臂包括塔架凸缘连接元件中的一个塔架凸缘连接元件,并且其中,在吊机的正常操作位置时,任意两个塔架凸缘连接元件之间的竖直距离小于1m、小于50cm或小于25cm。这样,提供了一种吊机,该吊机可以连接到位于塔架节段的上部部分处的凸缘。
