New Technology for Demolition of Main Cable of Cable Crane Cableway System
The cable crane has the advantages of large span,high construction efficiency,and can be used in nar-row sites and steep canyons.It has been used in domestic hydropower projects for more than 50 years.The existing cable crane cableway system of hydropower projects that uses traditional technology has the disadvan-tages for removing main cables,such as long demolition period and high risk of high-altitude operations.A new technology for the removal of the main cable of the cable crane ropeway system has been summarized and de-veloped,which completely solves the safety risks of aerial operations of main cable,eliminates the process of e-recting and dismantling temporary load-bearing cables and the process of installing and removing temporary bearings,effectively saves the construction period for the main cable removal and reduces the investment in re-sources such as temporary load-bearing cables and bearing distance ropes,and significantly improves the effi-ciency,economic benefits and social benefits.It has strong practical value and promotion significance.
