起重機軌道鋼軌鋪設安裝標準及注意事項

(1)起重機軌跡應經過墊塊中軌跡不得移動。 
(2)鋼軌接頭處必須有軌枕支承,不得懸空。在使用過程中軌跡不該移動。 
(3)起重機軌跡裝置后應契合下列請求: 
①塔式起重機裝置后,軌跡頂面縱、橫方向上的傾斜度,關于上反轉塔機應不大于3/1000;關于下反轉塔機應不大于5/1000。
②軌距差錯不大于公稱值的1/1000,
③鋼軌接頭間隙不大于4:11111,與另一側鋼軌接頭錯開,間隔不小于1. 5111, 
④軌跡行程兩頭的軌頂高度應不低于其余部位中最高點的軌頂高度。 
注gb/19462—1999中規定,塔機軌距答應誤差為其公稱值的±0.1%,但最大誤差為 ±6 mm,塔機裝置前,鋼軌頂面縱、橫方向上的傾斜度為2.5/1000;塔機裝置后該傾斜度為 5/1000。
