A lifting device includes a base part, a connecting part, and at least one shackle drop brake. The base part attaches to an object, such as a loading platform or a load. The connecting part serves to attach a sling, lifting, lashing or tensioning means and is pivotable about a swivel axis relative to the base part. The base part also has a bearing surface which defines an assembly plane. The shackle drop brake acts between the base part and the connecting part. The shackle drop brake has at least one holding point configured to hold a weight of the connecting part when the connecting part is in a swivel position that is angled with respect to a vertical axis extending from the assembly plane.

A lifting system for lifting a separate pallet with a heavy load is disclosed, the lifting system including two or more carrier elements and a suspension device in the form of a chain sling or a strap sling with double as many fastening ends as the number of carrier elements, wherein each of the carrier elements includes a stiff supporting beam and a distance element and is arranged so that two of the fastening ends of the suspension device can be fastened to the supporting beam in opposite ends thereof, and wherein the distance element is dimensioned and mounted onto the supporting beam in such a way that it prevents displacement of the carrier element relative to a pallet in the longitudinal direction thereof, when the carrier element is mounted transversely through the pallet. Furthermore, a carrier element for such a lifting system is disclosed.

A lifting apparatus clamps around the sides of a gang box to facilitate lifting and transporting the gang box. The lifting apparatus has a pair of lifting brackets a set of mounting points and a lateral clamp. The mounting points are support protrusions that extend from the lifting brackets to facilitate affixing the lifting apparatus to the bang box. The lateral clamp is connected in between the brackets and provides the force required to clamp the lifting apparatus around the gang box. Thus preventing the lifting brackets from becoming dislodged from the gang box.

A crane (16) for upending an elongate structure such as a monopile (28) supports elongate rigging elements that are connected to the structure at respective connection axes spaced longitudinally along the structure. At least one of those elements, of fixed length (36), extends to a first connection axis and at least one other of those elements, of variable length (34), extends to a second connection axis. A frame (24) suspended from the crane (16) supports a winch (46) that pays out the variable-length element (34) of the rigging to lengthen that element. This lowers the second connection axis relative to the first connection axis, which serves as a pivot axis about which the structure is upended.

A jack-up platform is described having a horizontal working deck that may be jacked up out of the water by moving its legs to a position wherein they take support on an underwater bottom. The jack-up platform further comprises a mooring system for mooring a floating vessel at a mooring side of the jack-up platform. The mooring system comprises an elongated support means for supporting a hull part of the floating vessel, and guiding means connected to the hull of the jack-up platform at the mooring side. The guiding means are able to rigidly hold the elongated support means in a support position, in which the elongated support means is within reach of the hull part of the floating vessel to be supported when the hull is jacked out of the water and the jack-up platform rests on its legs. A method for mooring a floating vessel using the jack-up platform is also described.

A system and method for removing or installing wind turbine blades, comprising a single spreader-type bar fitted with specialized end units with rotatable chain and/or cable for supporting the blade at two or more lift points. The inventive device allows for a single-crane lift of a wind turbine blade, with the ability to remotely control and fine tune the level and pitch of the blade during all portions of the lifting, lowering, installation and/or removal operations.
