Claim 16:
17. An anchoring and lifting system for a wind turbine tower comprising:
a tower base;
a plurality of base anchors attached to the tower base;
an anchor outrigger attached to and extending laterally outward from the tower base;
at least one secondary anchor attached to the anchor outrigger;
a hinge connecting the tower base and a tower for moving the tower between a raised position and a lowered position; wherein the hinge includes lateral mounting portions extending past a diameter of the tower;
a first lifting outrigger attached at a proximal end to one of the lateral mounting portions of the hinge;
a second lifting outrigger attached at a proximal end to another of the lateral mounting portions of the hinge and laterally spaced from the first lifting outrigger so that the first and second lifting outriggers are disposed on opposing sides of the tower;
a lifting outrigger cross beam interconnecting the first lifting outrigger and the second lifting outrigger;
a first static cable connected between a distal end of the first lifting outrigger and a hub attached to the tower;
a second static cable connected between a distal end of the second lifting outrigger and the hub attached to the tower; and,
a lifting cable attached between the lifting outrigger cross beam and a winch, wherein the winch is carried by the tower base, and wherein when the lifting cable is retracted by the winch the tower is moved to the raised position, and wherein when the lifting cable is extended by the winch the tower is moved to the lowered position.
