摘要： Method for lifting a wind turbine component The present invention relates to a method for lifting a wind turbine component, such as a rotor blade (2), gearbox or a rotor, with a lifting yoke (10) comprising a first structural body (20) comprising a crane hook attachment point (21), a first connection point (22) and a second connection point (23), a second structural body (30) comprising a third connection point (31) and a fourth connection point (32). First and second tensional elements (24, 25) such as slings or wires, are connected to the connection points, the length of the second tensional element being variable. An inertial measurement unit (40) determines the angle of the second structural body to the horizontal and the angle of the second tensional element is determined by an angle sensor. The distance (D) from the fourth connection point to the intersection between an axis (V) extending vertically through the center of gravity of the wind turbine component and the lifting plane is determined and provided to a crane operator. The invention also concerns a corresponding yoke.

摘要： A wind turbine generator nacelle (14) comprises a nacelle frame (44) having a first forward hub end and a second aft end. Dedicated transport fittings (46) are positioned at each of the ends of the nacelle frame (44). The fittings (46) are adapted to be engaged by transport frames (86) on first and second transport trailers (80) for supporting the nacelle frame (44) for transport by the trailers (80). A service platform (20) is mounted to the transport fittings (46) on the aft end of the nacelle frame (44) such that the service platform (20) is cantilevered off of the aft end of the nacelle frame (44).

摘要： Method and apparatus for a portable hoisting system (10) having an upright gin pole (38) which is attached to the upright standing very tall pole (14) or tower (15) using a plurality of straps (16). Extending away from the gin pole (38) is an angularly adjustable arm (40) which is user selectable to be either, e.g., at a 90-degree angle or a 45-degree angle, which arm (40) is supported by a brace (42) connected between the extension arm (40) and the upright gin pole (38). The gin pole (38) is hollow on its inside which allows a load line (18) to travel through the interior (60) of the gin pole (38) from its lower end to its upper outlet end and includes a plurality of pulleys (44) which allow the load line (18) to travel through the inside (60) of the hoisting system (10). Also included is a heel block (24) wherein one end of the load line (18) is connected to a capstan hoist (30) disposed on the front or rear end of a vehicle (32) and a ball (19) with hook (20) for supporting a load (22). Also included optionally is a tag line (34) connected to the load line (18) and being held by a ground member (36) for helping to control the movement of the load (22).

摘要： System, apparatus, device, kit, method and associated technique for safely and securely lifting wall and other structures to a vertical position. An electronic winch device that when connected to an end of a wall structure lifts the structure. A keeper or catchment such that when the electronic winch has hoisted the wall structure to a substantially vertical position, catches and keeps the wall structure in place, allowing the technician to more properly secure the wall structure. The apparatuses are also designed for portability and collapsibility, with structural members telescoping inside one another to minimize size in transport but securely configurable when extended and locked into place.
