Abstract: A turning system for turning wind turbine blade shell part carriers between an open position and a closed position about a turning axis, comprising: a lower blade shell part carrier having a support surface for receiving and supporting a lower wind turbine blade part; an upper blade shell part carrier and having a support surface for receiving and supporting an upper wind turbine blade part; and at least one turning device each including: a lower hinge element, such as a beam, arranged under the support surface of the lower blade shell part carrier; and a turning hinge having a lower hinge part attached to the respective lower hinge element, an upper hinge part attached to the upper blade shell part carrier, and an actuator configured for turning the lower and upper hinge parts relative to each other about the turning axis.
