A crane assembly for erecting a tower from a plurality of tower sections includes a first telescopic mast connected to a second telescopic mast. A crane is mounted on top of the first telescopic mast. The first telescopic mast is configured to increase in length from a retracted state in a first direction and includes a first clamp assembly that selectively grips portions of the tower. The second telescopic mast is configured to increase in length from a retracted state in a second direction opposite to the first direction and includes a second clamp assembly that selectively grips portions of the tower.

Crane assemblies and methods for erecting towers and wind turbines

The present disclosure relates to methods for rotating a locked rotor of a wind turbine in case of an imbalance in a rotor plane of the rotor, comprising: rotating the rotor using an inching tool to apply torque on a drive train of the wind turbine to reduce the imbalance in the rotor plane; and removing a locking pin from a locking disc operatively connected to the rotor after reducing the imbalance in the rotor plane. The methods further comprise estimating a direction of a torque load due to the imbalance in the rotor plane using one or more sensors, and impeding the inching tool to apply torque on the drive train of the wind turbine in the estimated direction of the torque load due to the imbalance. The present disclosure further relates to inching tools and to methods for installing rotor blades on a hub of a wind turbine.

Rotating unbalanced rotor hubs and installing wind turbine rotor blades

The disclosure relates to a crane () for erecting a tower including a plurality of tower segments (), the crane () comprising: a telescopic mast (), and a jib () rotatably mounted with respect to the telescopic mast () and comprising lifting equipment (). The telescopic mast () comprises a lower mast segment () having one or more lower clamp assemblies () for selectively gripping portions of the tower and a roller assembly () for rolling along the tower, and comprising one or more further mast segments () having an upper clamp assembly () for selectively gripping portions of the tower, the further mast segments () being slidable with respect to the lower mast segment (). The disclosure also relates to methods for climbing a tower with a crane () and methods for mounting a wind turbine tower.
