三峡摆塔式缆索起重机的工作机构特性

Characteristic analysis of operation mechanisms of luffing cable crane in the Three Gorge project

根据三峡摆塔式缆索起重机起升机构的具体结构特点,对其机构特性进行分析阐述;并介绍了牵引机构及配重系统的结构特性,以实际运行情况考证了这些机构特性的可靠性、稳定性及实际效果。

The hoisting mechanism of the luffing cable crane used in the Three Gorge project features four falls rope winding and has a rope guiding device to ensure correct rope winding. The driving sheave of crab traversing mechanism is covered with friction blocks and has an increased wrapping angle by the rope winding through a rope sheave. The crab traversing mechanism has a fixed, position- adjustable take - up weight.
