起重機的安全滑觸線：
Crane safety sliding contact line:
安全滑觸線是一種新型移動供電裝置，以其絕緣、安全、耐溫、抗振、節(jié)能等*性能逐步替代了舊式裸露角鐵及銅排滑觸線。
Safety sliding contact line is a new type of power supply device, with its insulation, safety and superior properties such as heat resistance, resistance to vibration, the energy conservation gradually replaced the old bare Angle iron and copper platoon sliding contact line.
安全滑觸線由填嵌在工程塑料型管或槽板中的光滑平整的 T2 銅排或嵌有導體的鋁型材作為載流體，組合成輸電導管，導管下有開口槽以利集電器運行，并由集電器的高銅基石墨電刷將電力導向工作電器。
 

Safety sliding contact line by filling embedded in type engineering plastic tube or plate smooth level of T2 copper platoon or are embedded in the wear resistance of aluminum conductor as a carrier fluid, combined into transmission tube, catheter with electrical open slot and set operation, and the collector of high wear-resistant copper cornerstone ink brush will work power oriented electrical appliances.
