鋼鋁拖鏈規(guī)格有TL45、TL65、TL95、TL125、TL180、TL225、TL250型，拖鏈寬度可按用戶要求定做，彎曲半徑從50-800之間。有三種支撐板的形式。
Specification for Steel Aluminium Tuolian has TL45, TL65, TL95, TL125, TL180, TL225, TL250, drag chain width can be customized according to user requirements, the bending radius from 50-800. There are three kinds of support in the form of.
（1）當拖鏈需承載較大管、纜負荷時、應選用高強度支撐板——整塊式
  (1) when the towline should carry a large pipe, cable load, selection of high strength support board -- integral
（2）當管纜的管接頭尺寸大于支撐板內腔孔徑或須經常拆裝、維修等時?？蛇x用支撐板——分開式
  (2) when the pipe joint pipe cable size greater than the support plate cavity aperture or subject to frequent disassembly, repair etc.. Can choose the support plate -- split
（3）安裝管纜的規(guī)格品種較多時，可選用支撐板——框架式 　
  (3) installed pipe cable specifications varieties, can choose the support plate -- frame　
鋼鋁拖鏈的材質：冷軋鋼和不銹鋼。
Steel Aluminium Tuolian material: cold rolled steel and stainless steel.
拖鏈適用于所有傳動方式．可隨意加長和縮短．TLG型鋼制拖鏈可承載數量多，重量大的電纜及油管，自由懸置長度大，支撐板可依顧客需要制作，使用于工作母機，移動機械等．此外，可通過改變銷軸獲得改變彎曲半徑．
Towline applicable to all transmission ways. Can lengthen and shorten the.TLG type steel towline bearing number, cable and pipe weight, free suspension length, support plate according to customers need to produce, used for machine tools, mobile machinery. In addition, the bending radius can be changed by changing the pin shaft.
