  • Telescopic tower assembly and method
    Patent number: 8919074
    Abstract: A method of constructing a tower structure by assembling a set of coaxial telescopic sections 2, 3a, 3b in position on site and then raising the assembled sections using hydraulic crawler jacks 8 and tendons 5. The telescopic sections are assembled or constructed in situ, starting with the inner section and then each subsequent section around the outside of the previously constructed sections. Each individual tower section may be cast in situ or assembled from multiple pre-fabricated segments. This method permits the construction of very tall structures while obviating the need for very large cranes. It also removes the design constraints on the height of the individual telescopic sections.
    Type: Grant
