Method and crane for handling a part of a wind power installationMethod and crane for handling a part of a wind power installation

The invention relates to a crane having a base provided with a boom, wherein distant from the base the boom is provided with a manipulator for handling a part of a wind power installation, particularly but not exclusively a rotor blade. The invention also relates to a method for handling a part of a wind power installation, in particular for moving said part to or from an upper end of an upstanding mast of the wind power installation, comprising the step of providing a crane with a base and a boom provided on said base, and providing the boom of the crane with a manipulator for handling said part of the wind power installation, particularly but not exclusively a rotor blade. The manipulator can also be used to handle other parts of the wind power installation, such as the generator, the gearbox etc.The invention relates to a crane having a base provided with a boom, providing distant from the base the boom is provided with a manipulator for handling a part of a wind power installation, particularly but not exclusively a rotor blade.

The manipulator can also be used to handle other parts of the wind power installation, such as the generator, the gearbox etc.

Such a crane and method for handling a part of a wind power installation is disclosed by US 8,757,402. This citation mentions the application of a crane with a manipulator connectable to the boom of the crane in a torque-rigid manner so that the position and/or alignment of the rotor blade received in the receiving unit of the manipulator can be fixed relative to the boom. For the assembly of the rotor blade to the hub of the wind power installation, the vanes are first brought into an assembly position via the movement of the crane. Thereafter fine alignment can take place by means of the manipulator. Although this citation mentions that the position and/or alignment of the rotor blade can be fixed relative to the boom of the crane, this does not address the problem that the position and/or alignment of the rotor blade is still relatively undefined with respect to the upstanding mast of the windmill installation, particularly when the boom of the crane extends to great heights. It remains therefore a challenge with the solution according to US 8,757,402 to securely and precisely position and align the rotor blade with reference to the hub of the windmill installation, notwithstanding the eventual fine tuning that can be provided with the manipulator since the position of the manipulator itself is relatively undefined with reference to the upstanding mast of the windmill installation. This problem further worsens when strong winds blow near the nacelle of the wind power installation, which is normally the case since the wind power installations are evidently located in windy areas.Such a crane and method for handling a part of a wind power installation is disclosed by US 8,757,402.

It is therefore an object of the invention to more securely and precisely handle all sort of parts of a windmill installation .It is therefore an object of the invention to more securely and precisely handle all sort of parts of a windmill installation.

According to the invention a crane and method for handling a part of a wind power installation are proposed in accordance with one or more of the appended claims.According to the invention a crane and method for handling a part of a wind power installation are proposed in accordance with one or more of the appended claims.

In a first aspect of the invention distant from the base the boom is further provided with a guide element which is arranged to cooperate during use with an upstanding mast of the wind power installation so as to restrict relative horizontal movement of the boom distant from the base with reference to the upstanding mast of the wind power installation. Applying this guide element on the boom at the far end from the base, and providing that this guide element at least partly fits around a circumferential surface area of the upstanding mast of the wind power installation effectively prevents relative horizontal movement of the boom distant from the base with reference to the upstanding mast of the wind power installation. In fact by this arrangement on top of the boom a point of fixation is provided that can operate as a secure base for the manipulator with a defined position relative to the upstanding mast of the wind power installation. This not only improves security and accuracy, but also makes possible that the crane can handle larger weights. In other words the capacity of the crane is also improved.In a first aspect of the invention distant from the base the tree is further provided with a guide element which is arranged to cooperate during use with an upstanding mast of the wind power installation so as to restrict relative horizontal movement of the tree distant from the base with reference to the upstanding mast of the wind power installation. Applying this guide element on the tree at the far end from the base, and providing that this guide element at least partly fits around a circumferential surface area of the upstanding mast of the wind power installation effectively preventing relative movement of the tree from the tree base with reference to the upstanding mast of the wind power installation.

This not only improves security and accuracy, but also makes possible that the crane can handle larger weights. In other words the capacity of the crane is also improved.

Preferably the manipulator is one of a robot dedicated for handling a rotor blade, and a second crane mounted on top of the boom and distant from the base for handling ancillary equipment to be mounted in or retrieved from a nacelle of the wind power installation.Preferably the manipulator is one of a robot dedicated for handling a rotor blade, and a second crane mounted on top of the boom and distant from the base for handling ancillary equipment to be mounted in or retrieved from a nacelle of the wind power installation.

Providing a second crane mounted on top of the boom distant from the base for handling ancillary equipment to be mounted in or retrieved from a nacelle of the wind power installation has the advantage that the complications of the crane system according to US 9,415,978 are avoided. In US 9,415,978 the crane is arranged in the nacelle of the wind power installation wherein it is anchored to the stable structural parts of the wind turbine nacelle. Although this provides a stable base with reference to the upstanding mast of the windmill installation, it is disadvantageous that US 9,415,978 requires for this purpose that the parts of the crane are individually transferred to and assembled in the nacelle, and that after its use the crane is disassembled and transferred back to ground zero. In the invention the second crane on top of the boom can be integrally lifted to or from the required height without requirement of being assembled or disassembled at the working height of the crane.Providing a second crane mounted on top of the boom distant from the base for handling ancillary equipment to be mounted in or retrieved from a nacelle of the wind power installation has the advantage that the complications of the crane system according to US 9,415,978 are avoided.
