    Abstract: A suspension arrangement (7) for attachment to a support (2, 17) being made from a magnetisable material is disclosed. The suspension arrangement (7) comprises a magnetic attachment means (8) and a glue surface (9) having a glue depression (10). The magnetic attachment means (8) comprises a magnetic material allowing the suspension arrangement (7) to be releasably attached to the support (2, 17). The glue depression (10) is configured for receiving a glue portion (11) in order to permanently attach the suspension arrangement (7) to the support (2, 17). The glue surface (9) is arranged in contact with the support (2, 17) when the suspension arrangement (7) is attached to the support (2, 17).

    Abstract: A transportation system (300) for, and a method (1104, 1106, 1108) of loading for transportation of, a segment (330) of a wind turbine tower are disclosed. The system has a transportation platform (304), the transportation platform having a centreline (320), and a segment support (306, 310) mountable on the transportation platform. The segment support is configured to permit tilting of a supported segment with respect to a pivot point (308) of the support. The segment support is further configured to receive a segment such that the centre of gravity (342) of the segment is offset transversely from: the support pivot point; and from the transport platform centreline. The segment support is also configured to, having received the segment, permit tilting of the segment with respect to the support pivot point to a rest position, and in the rest position the centre of gravity of the segment is alignable vertically with the transport platform centreline.

    Abstract: The present invention relates to an overhead travelling crane (2) for a nacelle (1) of a wind turbine, said travelling crane comprising at least a first suspension beam(3); a second suspension beam(4), said suspension beams being arranged with a space between them; a cross beam (5), said cross beam being movably connected to said first and second suspension beams so that the cross beam can be moved along the suspension beams; and at least one lifting device (6), said lifting device being movably connected to the cross beam. Said first and second suspension beams are parts of concentric circles, said -concentric circles sharing the same centre and having different radii. The cross beam may be inclined.
