由于企業實地的各種原因許多廠房的起重機都需要建在室外，方便提卸貨物，導致了滑觸線也需要按在室外，導致了滑觸線長時間暴露在日曬雨淋之下往往會導致滑觸線外殼的碎裂，更嚴重的情況是隨著時間的風化，提掛架也會隨著時間的推移而變得很脆弱，從而導致滑線的不穩，直接影響到行車的運行，如何避免這類事情的發生呢?

　　Due to various reasons many plant field enterprises need to build crane outdoors, convenient for carrying and unloading goods led to a sliding contact line is also required by the outdoors, caused the sliding contact line long time exposure under the sun and rain often leads to the sliding contact line shell fragmentation, more serious situation is as time weathering. Put rack will over time become very fragile, which leads to the instability of slip line, directly affect the driving operation, how to avoid this kind of things?

　　1、現場環境有條件的話，盡量在滑觸線的上方按一個棚子

　　1, the site environment, conditional, as far as possible in the touch of the line above a shed

　　2、管式滑觸線可以在滑線外殼的基礎上增加一層鋁合金的外殼

　　2, the tube type sliding contact line can be added to the shell of the aluminum alloy on the basis of the sliding wire shell

　　3、堅持每個季度都進行檢查，發現有碎裂情況立馬更換相應配件

　　3, insist on quarterly inspection, found that there is fragmentation, immediately replace the corresponding parts
