Abstract: A gripping device (76) is provided for lifting a preform for a wind turbine blade from a preform mould (71). The gripping device (76) comprises a base frame (62), a plurality of arms (78) slidably mounted on the base frame (62), each arm (78) having a proximal end and a distal end, a plurality of gripping members (86) for gripping a top surface (75) of the preform. The vertical position of one or more arms (78) of the gripping device (76) relative to the base frame (62) may change when lowering the gripping device (76) towards a preform to reflect the top surface (75) of the perform.

Abstract: The present invention relates to a moulding assembly (100) for manufacturing a shell part of a wind turbine blade, and to methods of manufacturing a shell part of a wind turbine blade using the moulding assembly. The moulding assembly (100) comprises a blade mould (96) with a moulding cavity (97), a gripping device (76) for releasably engaging a preform (98) for the shell part, and a lifting device (102). The lifting device comprises a first hoisting device (104a) and a second hoisting device (104b), each of the first and second hoisting devices comprising a respective load engaging member (110a, 110b) for connecting the first and the second hoisting devices (104a, 104b) to the gripping device.
