    Abstract: Self-hoisting crane (1) and method of mounting and operating such crane The self-hoisting crane is adapted to be hoisted from ground to a nacelle (2) or a tower (46) of a wind turbine (3) by operation of a cable winch (9) arranged at ground (10) and is adapted to be operated in its mounted position on the nacelle or on the tower by operation of the same cable winch. The cable extends from a hook block (6), out through a pedestal (4) of the crane, from the nacelle or from the tower and to the cable winch at the ground. The self-hoisting crane is provided with a cable crawler (11) having at least one motor driven traction sheave (122) adapted to, during operation of the self-hoisting crane, transfer a pulling force to the cable (8) through friction. The cable crawler is shiftable between an active state (13) in which the traction sheave may transfer a pulling force to the cable and a passive state in which the traction sheave may transfer no pulling force to the cable.

    Abstract: A base (100) for supporting a portable crane for handling components of a wind turbine. The base (100) is mountable on the wind turbine, and configured to be switched between a first configuration and a second configuration. In the first configuration the base (100) is configured for being supported by a main bearing of the wind turbine to allow the portable crane to lift a gearbox (303) of the wind turbine. In the second configuration the base (100) is configured for being supported by a bed plate of a nacelle of the wind turbine to allow the portable crane to lift the main bearing (304). The base is configured for supporting the portable crane while switching between the first configuration and the second configuration. A method for removing a main bearing of a wind turbine is also disclosed.

    Abstract: A cantilever hoist device (100) adapted for lifting a load (200) in a spatially limited environment (300) is disclosed. The device (100) comprises a support column (110) having a proximal end (112) and a distal end (118), wherein the proximal end (112) is adapted to secure the support column (110) in an upright position. Moreover, the device (100) comprises an elongated, stiff, and rigid cantilever arm (120) hingedly mounted at the distal end (118). Additionally, the device (100) comprises a drive unit (130) arranged to displace the load towards or away from the cantilever arm (120) using a lifting medium (140) passing one or more pulleys (151, 152, 154, 156, 158), wherein the drive unit (130) comprises a winding body (135) onto which the lifting medium (140) is rollable to displace the load (200). The drive unit (130) is mounted at the distal end of the support column (110).
