Abstract

The present invention proposes a technique to install tower section of a wind turbine. The technique includes a door hinge or a trailing device as support to install the tower section without utilizing a trailing crane. One side of the door hinge is installed at the tower section flange when supported on ground. Other side of the hinge is laid on floor. The door hinge includes an active J hook, which opens and closes to fit the tower section for installation. The door hinge includes adjustable base plate, rubber support and heavy-duty pillow block to grip the tower section for installation.

TAILING DEVICE FOR TOWER LIFTING

BACKGROUND

The present invention relates generally to a wind turbine and more particularly to a tailing device for wind turbine installation.

In a standard wind turbine installation process, tower section is lifted for installation by two cranes. Two cranes include a main crane and a tailing crane. The main crane lifts the tower section from topside and the tailing section lifts the tower section by bottom flanges. The tailing crane allows the main crane to align the tower section from horizontal to vertical position. When the tower section is completely vertical then the tailing crane starts lifting the tower to final position.

A conventional technique includes a wood block and material block for installation of the tower section. However, safety issues are detected for installation using the conventional technique.

Another conventional technique includes a moving platform to drive the tower section base for installation. However, the conventional technique includes wheels to move and position the tower section in correct place.


It would be desirable to have an efficient technique to install the tower section in the wind turbine.
