A new method for installing one or more electric cables (60) in a wind turbine tower section (100) is provided. The method comprises providing the wind turbine tower section (100) in a substantially horizontal orientation and installing a zip line (20) inside the wind turbine tower section (100), between a first end (120) and a second end (130) of the wind turbine tower section (100). The method further comprises coupling a second end of the electric cables (60) to the zip line (20) at a location near the first end of the wind turbine tower section (100), drawing the second end of the electric cables (60) through the wind turbine tower section (100) along the zip line (20), decoupling the second end of the electric cables (60) from the zip line (20), and removing the zip line (20) from the wind turbine tower section (100). The method further comprises anchoring a first end of the electric cables (60) to the wind turbine tower section (100), at a location adjacent the first end of the wind turbine tower section (100), and anchoring the second end of the electric cables (60) to the wind turbine tower section (100), at a location adjacent the second end of the wind turbine tower section (100).

A transport apparatus for use in the transport of a heavy structure includes a shape-adjustable adapter realized to adjust between an initial shape and a mating shape; and an actuator configured to effect a change in shape of the shape-adjustable adapter into its initial shape to facilitate positioning of the adapter relative to the structure; and to effect a change in shape of the shape-adjustable adapter into its mating shape to engage the shape-adjustable adapter with a surface of the structure. A method of securing a frustoconical structure during transport is further provided.

A system is used for lifting a heavy oversized structural element. At least two opposing lifts are placement adjacent opposing sides of the element. Each lift includes a base, a tower, an elevator, and an actuator. The tower extending vertically from the base, and the elevator is disposed on the tower. A support extends from the elevator outward from the tower to engage a point on the element. A guide of the elevator is configured to ride along a rail of the tower. The actuator is connected to the elevator and is configured to move with the elevator vertically along the tower. The actuator can include a strand jack disposed on the elevator. Hydraulic operation of the stand jack moves the jack and elevator along a strand extending along the tower. The arrangements of the lifts leave space below the raised element free for access to other operations.

Provided is a vertical axis wind power generation device including a wind turbine of a vertical axis type including a support column, a main shaft disposed on an upper portion of the support column so as to be rotatable, a plurality of blades coupled to the main shaft through arms; a power generator; and a container having a standard dimension for freight transport. The wind turbine is accommodatable in a folded or disassembled state in the container together with the power generator. The container is provided with a support-column fixing part configured to fix the support column of the wind turbine to the container. The container may include an inclining mount inside the container, the inclining mount being configured to accommodate a folded body of the wind turbine.

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).
