dc.description.abstractHuge costs are associated with the construction of overhead power lines in the Extra High Voltage category. More economical ways to perform the different aspects of line construction are constantly sought. One area of construction, which is the focus of this study, is alternative erection methods for the towers that support the conductors. Mobile cranes have become the dominant piece of equipment to erect these towers as they occupy a relatively small footprint, and although relatively quick, these cranes do come at a substantial cost. Furthermore, their mobility in terms of terrain is limited. Hence, this paper investigates a promising concept to lift guyed V towers used in overhead power line construction, utilising only winches and a gin pole. Once the tower is correctly assembled and support equipment like gin pole, hinge mechanism and winches are in place, a control system ensures autonomous lift in two stages. This paper further looks at scale model testing that was conducted to prove the concept, the associated electronic control system required and an analytical tool which provide support as well as an air cushion as a future alternative for the gin pole. Comparison of the analytical tool data versus other calculated methods is presented and its importance is explained.en_US
