At 4 pm on July 10, a 106.6-meter-high cable crane main tower of Sichuan Guanyinyan Hydropower Station landed safely in a pre-empted area, marking the phased completion of the world's largest 30-ton radial cable crane demolition project. The task of disassembling the main structural parts. During the construction of Guanyinyan Hydropower Station, two 30-ton radial cable cranes were installed. The height of the cable crane tower was 106.6 meters, the span was 1365 meters, and the single main cable weighed about 103 tons. The arrangement was fixed on the right bank and mobile on the left bank.
It is understood that this world-class large-scale cable crane equipment has played an important role in the construction of the dam. After 5 years of operation, it has completed its historical mission. The cable mechanism parts and electrical parts have been idle for a long time, and there are doubts about the safety status of the cable crane. If it is not demolished as soon as possible, it will cause major safety hazards to the operation of the dam and power station. At the same time, its demolition difficulty is also world-class.
