鋼制拖鏈-鋼制鏈條的組成及工作原理：
1、工作原理
     構件整體放置在特殊結構的導軌上，隨著設備的運行，電纜或水纜隨鏈條在移動設備的拖動下一起移動，實現(xiàn)移動設備的供電、供水。Components placed in the special structure of the whole rail, with the operation of equipment, cables or water cable with devices, drag the chain together under , devices to achieve power and water supply

2、主要組成部分　
      鋼制拖鏈又被稱做為（鋼制鏈條）拖鏈系統(tǒng)主要由鏈條、導軌、滑軌、導槽、支架、牽引架、浮動頭等部件組成。其主體構件鏈條是由工程塑料制成的一種特殊結構，配有隔片、橫桿、牽引端和固定端等附件，可將不同規(guī)格的電纜、水纜規(guī)則有序地排列放置在金屬拖鏈鏈條內，通過牽引端和固定端分別與設備和固定點相連。Steel towline was again called for the （steel chain） towline system mainly consists of chain, guide rail, rail, guides, supports, traction frame, floating first-class components. Its main component is a chain of plastic made of a special structure, with every film, bar, towing accessories such as side and fixed side can be different specifications of cables, cable rules of orderly arrangement of water placed in a metal trailer chain chain, through the traction side and fixed side and fixed points, respectively, connected with the equipment
注：如果拖鏈長度超過允許不用支承輪時，建議在拖鏈下面增加支承輪等，以免拖鏈下沉并保證拖鏈具有*的移動性能。Note: If you do not support drag chain wheel longer than allowed, the proposed increase in the drag chain bearing the following round so as to avoid sinking and to ensure the towline towline has the best performance
