大高差输电线路施工中，货物运输最经济的方式为索道运输方式。索道运输系统包括工作索、支架、货车、驱动装置、地锚等，其中驱动装置是索道运行的关键机具。在研究各施工单位现有索道施工的基础上，研制了新型驱动装置，使其适合高差达1 700 m的500 kV丹巴—大杠输电线路工程施工，为项目的顺利完成提供了技术保证。

Ropeway transportation is the most economical method for goods transport in power line project with large height difference. The whole system consists of work rope, scaffold, goods container, driving device and ground anchor, etc, and the driving device is the most crucial. Based on the research of the ropeway used in other construction units, a new driving device was developed. It is suitable for the construction in 500 kV Danba-Dagang power line project with 1 700 m height difference, which can provide the technical guarantee for the successful completion of the project.
