To upend and lift an object, e.g. a foundation member of an offshore wind turbine, e.g. a monopole, use is made of an upending and lifting tool, wherein, with the tool suspended from one or more hoisting cables, e.g. from a crane hook of a crane, and with the frame of the tool initially in vertical orientation, a routine is performed which includes operating one or more shifting actuators, thereby moving a cable shifting member and engaging a cable engagement surface with the one or more hoisting cables at a height above a pivot axis. Further continuing this motion of the cable shifting member and thereby applying a cable shifting force on the one or more hoisting cables results, in reaction, in a pivoting of the frame into the horizontal orientation thereof.

A moving system and method of moving an item, for example a construction component. The moving system includes a first guide cable mounted between first and second mounting points, a first member arranged for movement along the first guide cable between a first position and a second position, the first member arranged for connection to an item to be craned into position, a second guide cable mounted between first and second mounting points, a second member arranged for movement along the second guide cable between a first position and a second position, the second member arranged for connection to the item to be craned into position, and a lifting support arranged for connection to a moving device and to provide support for the item during moving of the item.

The present invention relates to a lifting device for lifting and vertically, and possibly horizontally, replacing an object. The lifting device comprises a first unit (1) configured with one or more catching parts such as suction pads and a second unit (2) configured to control vertical and optionally horizontal position of the object. The second unit (2) comprises a first attachment position and a second attachment position and the first attachment position is fixed to a vertically extending part (3) of the first unit (1); the second attachment position is fixed to a sliding member (10) of the first unit (1) by a rigid joint configured to transfer all movements induced at the second attachment position by the second unit (2) to a sliding member (10) of the first unit configured to slide between two positions along a longitudinal member (11) of the first unit.

A lift system for a rotor blade of a wind turbine includes a lifting device having a structural frame body having a root end and a tip end. The root end supports a root cradle and the tip end supports a tip cradle. The root and tip cradles each have a profile that corresponds to at least one exterior surface of the rotor blade so as to receive and support at least a portion of the rotor blade. Due to a shape of the rotor blade, when the rotor blade is installed in the lifting device and lifted uptower, the rotor blade can experience an asymmetric loading. Accordingly, the lift system also includes a variable airflow assembly coupled to tip end of the lifting device. The variable airflow assembly includes at least one surface moveable between a plurality of positions having varying resistances so as to counteract the asymmetric loading.
