The invention relates to a method for moving a wind turbine component, such as a wind turbine hub, from a transportation position to a wind turbine assembly position. The method comprises the steps of: attaching a handling unit to a structural part of the wind turbine component, operatively connecting the handling unit to a wire of a crane system, lifting the wind turbine component with the crane system to an assembly position of the wind turbine, the handling unit and the wind turbine component being suspended from a wire of the crane system, and rotating the wind turbine component with the handling unit during the lifting of the wind turbine component in order to orientate the wind turbine component for assembly. The invention also relates to a handling unit and a wind turbine hub and use hereof.

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.

A lift coupling system includes a lifting base attachable to an object. The lifting base includes a housing. Lift pins move between a retracted state within the housing and an extended state wherein a portion of each of the lift pins extend outwardly from the housing. An actuator moves the lift pins between the retracted and extended state. A lift collar includes a lift collar body configured to fit about the housing. The lift collar contacts and couples the lift pins to the lift collar when positioned about the housing and the lift pins are in the extended state and decouple therefrom when the lift pins are in the retracted state. At least one lift tab may be arranged on the lift collar body configured to enable lifting of the lifting base and the object thereby when the lift collar is coupled to the lifting base.

A wind turbine blade lifting device is provided, comprising a backing member adapted to contact an interior surface of a wind turbine blade; a connector rod having an upper end and a lower end, wherein the lower end is rotatably connected to the backing member; a cover plate connected to the connector rod, wherein the cover plate includes an alignment member; a primary lifting shackle rotatably connected to a base member engaged with the connector rod; and a securing nut threadably connected to the upper end of the connector rod. One or more spacers are positioned around the connector rod between the cover plate and an exterior blade surface. The device preferably includes a holding tool connectable to the upper end of the connector rod. The cover plate preferably includes one of more secondary shackles to enable engagement with other rigging equipment.

An aspect of the present invention provides a pickup system which makes, even in a case of transporting a load by using a single unmanned flying object, the unmanned flying object and the load less likely to tilt. A pickup system (1) includes: a holder (11) for holding a load (L); a measuring instrument (14) for measuring the position of the center of gravity of the holder (11) holding the load (L); and a controller (15) for moving, to a position immediately above the position of the center of gravity of the holder (11) holding the load (L), a connector (12) which is attached to the holder (11) in a movable manner and which is for connecting the holder (11) to a drone (D).

The present invention relates to a tool for mounting, rotating and loading sections of solar trackers on autonomous transportation means in order to transport them to the specific location of said solar trackers in the field, wherein the fastening and rotating tool for mounting sections of photovoltaic solar trackers makes the pre-assembly, transportation and installation of the solar tracker section possible, reducing the mounting time of each operation. The invention also relates to an associated system and method that makes use of the fastening and rotating tool for mounting sections of photovoltaic solar trackers.

A management system includes: a plurality of machine tools each including a base plate; a plurality of storage plates; an object holder enabling an object to be placed thereon; a conveying unit including a fetching unit that is configured to secure or release said object holder, and a bridge crane that is configured to move the fetching unit among the base plates and the storage plates; and a control unit controlling the bridge crane to move the fetching unit to where the object holder is located, and controlling the fetching unit to secure the object holder, and controlling the bridge crane to move the fetching unit along with the object holder to another location to release the object holder.

A trench roller lifting adapter is for inserting/removing a trench roller into/from a trench absent intervention with the trench roller within the trench by a worker and saves time required for compacting dirt in the trench. The adapter has an upper portion configured for interaction with a hook attached to a cable dangling from a crane, excavator, tractor, or other type of construction equipment used to insert/remove the trench roller into/from a trench. The upper portion has a front portion and an opposed back portion with a pin and gap extending therebetween. Each of the front and back portions include respective guide members adapted for guiding the hook toward and into engagement with the pin. The adapter also has a lower portion depending from the upper portion that is configured for secure coupling to the trench roller to be moved into or out of the trench.
