Abstract: The system (1) for lifting and controlling the horizontal orientation and/or position of components (90), such as wind turbine main components, during installation and/or dismounting of said components comprises: a crane boom arrangement (3) and one or more lifting lines (3a) guided by said crane boom arrangement (3) for lifting said components. The system moreover comprises a lifting device (10) comprising a crane connection arrangement (11) connected to said one or more lifting lines (3a), a frame arrangement (12) connected to said crane connection arrangement (11), a first and a second steering wire guide (13a, 13b) configured for guiding steering wires (20a, 20b), and a component connection arrangement (30) connected to said frame arrangement and configured to be connected directly or indirectly to the component to be lifted.

Abstract: System (1) for craneless blade (6) mounting and dismounting at wind turbines (2), wherein the system (1) at least comprises a blade tip beam (9) to be fixed at the blade (6) and a blade supporting structure (15) to be connected with and to guide and secure the blade tip beam (9) while the supporting structure (15) is displaced in a substantially horizontal direction, whereby total control of the blade (6) when moved from vertical position towards horizontal position and until the blade (6) is safe on a cradle or support (15) or opposite during mounting is achieved.
