An arrangement for lifting a tower wall portion of a wind turbine is provided. The arrangement includes a bar, a first holding member and a second holding member. The bar is connectable to a coupling element of a lift. The first and second holding members have respective first and second engagement portions adapted for engaging the tower wall portion at a first position and a second position respectively, the first position being different from the second position. The first and second holding members are releasably lockable at the bar such that the first engagement portion and the second engagement portion are a first distance away from each other. The first and second holding members are also releasably lockable at the bar such that the first engagement portion and the second engagement portion are a second distance away from each other, the second distance being different from the first distance.

Arrangement for lifting a tower wall portion of a wind turbine and method for lifting a tower wall portion of a wind turbine

A lifting fitting for lifting a series of elements of different sizes in a wind turbine is proposed. The lifting fitting has a base plate having at least one central slotted hole shaped to accommodate a fastener for fastening the lifting fitting to an element to be lifted, at least two outer slotted holes each shaped to accommodate a further fastener for fastening the lifting fitting to an element to be lifted. The outer slotted holes are arranged transverse to the central slotted hole. The lifting fitting is connected to a lifting apparatus for lifting the element. A method of assembling the series of elements is proposed. The elements are successively lifted into place. The lifting fitting can be used in the assembly of a wind turbine tower having individually liftable tower sections for lifting the tower sections into place.

A mounting bracket device and method for mounting a blade of a wind turbine to a transportation device are disclosed. The mounting bracket device includes a clamping device for holding the blade, an adjustment system, and a connecting system adapted for being removably connected to the transportation device. The connecting system removably connects the clamping device and the adjustment system to the transportation device. The adjustment system is adapted to align the clamping device with respect to the transportation device around the first rotary axis and around a second rotary axis.

Tip end bracket

At least one blade of the wind-turbine is attached firm but detachable with the tower by a fixture. The tower and the attached blade are transported to a planned site. The tower and the attached blade are brought together into an upright position in a single lift-action. A hub and a nacelle of the wind-turbine are mounted on the top of the tower. A wire of a winch, which is located inside the nacelle or the hub, is connected with a root of the blade. The blade is detached from the tower by unlocking the fixture. The blade is lift up to the hub for its attachment there.
