CA 2418021

A tower for supporting permanent or temporary wind power generation, communication, lighting and measurement apparatus comprises a plurality of pivotally interconnected, flange associated tower sections, and a tower erection method not requiring the use of a crane. Tower sections are assembled at the ground level of the installation site by interconnecting the adjacent sections with hinges, with the base tower section temporarily hinged to the tower foundation. Winch assemblies secured to the tower foundation are activated to pull on winch cables attached to the hinged tower sections to lift and tilt the tower sections upwardly, in sequence using, in part, the ground surface vertical forces counter-acting the weight of the tower at the contact points with the ground. The addition of permanent leverage beam structures mounted on the upper tower section facilitates the pivoting of the upper tower section to a standing position.
