A safety device comprising two straps, the first strap being of a shorter length and a smaller fracture strength, and the second strap being of a longer length and a larger fracture strength, with one end of the first strap and one end of the second strap being adapted to be attached together to a hoisting rope, and the other end of the first strap and the other end of the second strap being adapted to be attached together to a tie back attachment point.

A lifting device comprises three or more links hingedly joined end-to-end such that the lifting device is able to hingedly move in a first direction from a linear arrangement to a bent arrangement but is not able to hingedly move from the linear arrangement to a bent arrangement in a second direction opposite the first direction.

A device for facilitating handling of a wind turbine blade is provided. The device includes an inflatable member adapted to be arranged at the wind turbine blade such that the inflatable member covers at least a part of the wind turbine blade, wherein, when the inflatable member is arranged at the wind turbine blade and inflated, an aerodynamic drag coefficient of the wind turbine blade with the arranged inflatable member is less than an aerodynamic drag coefficient of the wind turbine blade. Further, there is described a system for handling a wind turbine blade, and a method of facilitating handling of a wind turbine blade.

A system for lifting a wind turbine rotor blade, including a wind turbine rotor blade, a lifting device having a sling, the sling supporting the wind turbine rotor blade at a longitudinal position where the wind turbine rotor blade has an aerodynamic profile, a leading edge and a profile chord arranged horizontally, and a leading edge protector having a front portion placed at the leading edge and a lower leg extending from the front portion and placed below the wind turbine rotor blade, wherein the front portion and the lower leg are formed as a sandwich construction having an inner top layer, an outer top layer and a core material, wherein a thickness of the core material increases from a free end of the lower leg towards the front portion in order to reduce a deformation of the wind turbine rotor blade at the leading edge.

There is described an aircraft configured to be able to hover, comprising a fuselage; and a support element adapted to support a load, made of elastically deformable material and constrained to said fuselage; the support element being movable in an operating position in which it is arranged at least partially outside said fuselage and supports said load; the aircraft comprises a sock surrounding the support element arranged in said operating position; the sock is configured to contain the elastic return of the support element, in case the support element arranged in said operating position is sheared off.

The present invention relates to a shackle. The shackle comprises a shackle body for use with a shackle pin. The shackle body comprises a flexible elongate member comprising at least one length of rope circuitously formed so that the flexible elongate member passes through itself and defines three sequentially adjacent noose portions Three sequentially adjacent noose portions comprise an intermediate noose portion and two end noose portions at opposing ends of the shackle body.
