钢制拖链-钢制链条的组成及工作原理：
1、工作原理
构件整体放置在特殊结构的导轨上，随着设备的运行，电缆或水缆随链条在移动设备的拖动下一起移动，实现移动设备的供电、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、主要组成部分　
钢制拖链又被称做为（钢制链条）拖链系统主要由链条、导轨、滑轨、导槽、支架、牵引架、浮动头等部件组成。其主体构件链条是由工程塑料制成的一种特殊结构，配有隔片、横杆、牵引端和固定端等附件，可将不同规格的电缆、水缆规则有序地排列放置在金属拖链链条内，通过牵引端和固定端分别与设备和固定点相连。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：如果拖链长度超过允许不用支承轮时，建议在拖链下面增加支承轮等，以免拖链下沉并保证拖链具有*的移动性能。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
