    摘要: Hoisting systems are provided for mounting a hub (108) on top of a tower, the hub carrying a first and a second blade (103, 104) forming a bunny ears configuration, and a third blade (105). The system comprises a crane (100) for pulling up the hub to the top of the tower, and a blade support () for supporting the third blade at a supported blade portion. The system further comprises a hub-blade coupling device configured to assist in coupling a root portion of the third blade to a coupling portion of the hub. The hub-blade coupling device comprises a hub mount structure configured to be removably fixed to the hub, a blade mount structure configured to be removably fixed to the third blade, and a connector rotatably coupling the hub mount structure and the blade mount structure. Methods are provided of mounting a hub on top of a tower by using any of said systems.

    摘要: The present invention relates to a hydraulic installation where sediment concentration in the water flow circulating through the cited installation is monitored continuously. According to the invention, the hydraulic installation comprises a pressure-reducing device and a primary sensor: the pressure reducing device decreases the pressure and discharge of upstream water flow, comprising sediments, allowing that the primary sensor can operate continuously measuring sediment concentration from the upstream water flow. The hydraulic installation also comprises a calibrating device, providing the primary sensor with a reference value to be used for comparison matters and for establishing the content of sediment in the water flow.
