：输电线路大跨越塔较高，且处于大江、大河或海边，气象条件相对比较恶劣。随着对大跨越塔运行要求的不断提高，对登塔设施安全性、舒适性、方便性等方面提出了更高的要求。通过对爬梯、走道和平台等各种常用登塔附属设施的功能特点及设计方法的总结，可为大跨越塔辅助结构的设计提供参考。

The towers for large-crossing transmission lines are usually high and located on the riverside or seashore, where the climate conditions are poor. As the operation requirement of the large-crossing towers is increasing, such requirements as comfort and convenience are also proposed for the tower-ascending facilities on the prerequisite for safety. The paper summarizes the functions and design method of various common tower-ascending facilities such as the shackles, ladders, elevators and tower-climbing machines, which can be used as a reference for designing auxiliary structures of large-crossing towers.
