ABSTRACT:
A method, a system, and a device for erecting a tower. The method comprises assembling proximate to the ground a base section, top section, and one or more intermediate sections of the tower into an assembled tower lying in a substantially horizontal first plane, the assembled tower comprising a top end including the top section and a bottom end including the base section. The method also includes orienting the attitude of the assembled tower using a lift initiator to lie in a second plane defining an acute angle to the first plane, so that the top end of the tower is higher in elevation than the bottom end. The method also includes lifting the assembled tower from the second plane to a vertical plane with a primary lift assembly and coupling the assembled tower to the foundation. The primary lift assembly may comprise a pulley having a continuous loop of cable connected to a counter-balanced tackle-block system.
