ABSTRACT:
A tall tower is divided into an upper section with a tower top and a lower section with a tower bottom. The sections are hinged together. The lower section is hinged to a tower base. A telescoping crane is attached to a lift point on the lower section. The crane is extended to lift the sections to the vertical position with the lower section resting on the base and the tower top of the upper section near ground level. A heavy load is attached to the tower top end using a small ground crane while the tower top of the upper section is near ground level. The telescoping crane is attached to another lift point on the upper section to partially lift the upper section, which is supported in this position. The telescoping crane is relocated and reattached to the lift point on the upper section. The telescoping crane is fully extended to raise the upper section and load to vertical above the lower section.
