Die outomatiese oprigting van 'n kabelgesteunde V-vormige kragtoevoertoring: 'n Gevallestudie.

The construction of overhead power lines in the Extra High Voltage category is a costly business. When erecting towers that support the conductors, mobile cranes have become the dominant piece of equipment to erect these towers. Although relatively quick, these mobile cranes do come at a cost and alternative erection methods will be very attractive for contractors responsible for construction. This paper investigates alternative options to erect overhead power line towers with specific emphasis on the use of gin poles and winches for the erection of the type 520B guyed V-tower thereby eliminating mobile cranes. The work presented here also proposes the use of novel methods like air cushions and a degree of automation to lift these guyed V-towers autonomously. Scale modelling is used to confirm experimental findings of the study. [ABSTRACT FROM AUTHOR]
