With the rapid development of 1 000 kV UHV projects, steel tube towers are widely used in projects. The steel tube towers in “Anhui Electricity Eastward Transmitting” project have the characteristics of big, long, heavy, etc., so the assembly and erection construction is rather difficult. In order to ensure the safety of project construction, it is necessary to find safe, efficient and economic construction methods and hoisting equipments. The QST-100 double horizontal arm ground holding poles were used in projects which could successfully solve the problem of difficult assembly and erection of steel tube tower. Finally, through the introduction of holding poles' performance and hoisting process, as well as the comparison with conventional construction methods, the superiority of holding poles were verified, which were worth of popularization and application in follow-up projects.
