摘　　要：三峡摆塔式缆索式起重机塔架的下部支承选用径向轴承,可避免塔架纵向摆动时在塔架截面上产生弯矩;塔架底部设置了可阻止塔架扭动的防扭装置,塔架顶部采用可摆动的牵引索上支悬挂滑轮支架,可减少塔顶与塔架底部导向滑轮间的牵引索的斜拉,塔架标准塔节的结构便于制作及现场拼装。This paper covers a luffing cable crane used in the Three - Gorge Project. The radial - spherical plain bearing as the tower lower support avoid producing bend moment when the tower swings. Anti - twist device is installed in the bottom of tower. Swinging upper pulley bracket can remove slant drawing of the cables betwcen the upper pulley and the lower one. It also features standard tower segments that are easy to be manufactured and assembled on field.
