A counterweight tool includes an attachment element, a lever arm, a counterweight element, a first locking mechanism, and a first crane connection point. The attachment element is arranged to be attachable to a component of a wind turbine. A lever arm is pivotally connected to the attachment element about a pivot point, the lever arm being pivotable between a first position, in which the lever arm is disposed at a first angle relative to the attachment element, and a second position, in which the lever arm is disposed at a second angle relative to the attachment element, the difference between the first angle and the second angle being greater than 25 degrees. A weight element is attached to the lever arm with a spacing from the pivot point, and a first locking mechanism is arranged to lock the position of the lever arm relative to the attachment element in a second position. The first crane connection point is arranged such that when the crane lifts the counterweight tool through the first crane connection point, the lever arm forms an angle of less than 30 degrees with the vertical direction, and when the attachment element is fixed in position relative to the crane, the lever arm forms an angle of less than 30 degrees with the vertical direction. Lifting or lowering the lever arm by the crane via a first crane connection point causes the lever arm to pivot about a pivot point from a first position to a second position.

    一种配重工具,其包括附接元件、杠杆臂、配重元件、第一锁定机构和第一起重机连接点。所述附接元件设置成可附接至风力涡轮机的部件。杠杆臂围绕枢转点可枢转地连接至附接元件,所述杠杆臂在第一位置和第二位置之间是可枢转的,在第一位置,杠杆臂相对于附接元件以第一角度设置,在第二位置,杠杆臂相对于附接元件以第二角度设置,第一角度和第二角度之差大于25度。配重元件附接至杠杆臂并与枢转点之间具有间距,第一锁定机构设置成将杠杆臂相对于附接元件的位置锁定在第二位置。第一起重机连接点设置成,使得当起重机通过第一起重机连接点提升配重工具时,杠杆臂与竖直方向之间成小于30度的角度,以及当附接元件相对于起重机固定就位时,通过起重机经由第一起重机连接点提升或降低杠杆臂会导致杠杆臂围绕枢转点从第一位置枢转至第二位置。
