Among all the drag chains we made, this TL series steel drag chain is a premium cable carrier consists of such main parts as chainplate(made of chrome-plated steel plate), support plate(aluminum alloy), hinge pin(alloy steel) and etc. It could stop the relative motion between cable/rubber tube and chains and avoid deformation.

Features of Steel Drag Chain
1. As the chainplate is plated with chrome coatings, this steel cable carrier has a novel scientific design and is highly flexible in operation, easy in installation and uninstallation;
2. Since the drag chain is made of high-strength abrasion-resistant materials and equipped with premium parts like hinge pin made of alloy cooper, it is highly resistant to abrasion, more flexible to bend, durable in use and hard to be deformed.

Selection
1. D1(diameter of inner cavity hole)=d ≈0.1d, d=outer diameter of wire/cable/ liquid or gas pipe;
2. The height of the energy chain(hg) and its model(TLXX) are determined by the maximum diameter of the of the inner cavity hole(Dmax) of the support plate;
3. The support plate type and the bending diameter are set depending on the application the drag chain;
(1) If used for heavy-duty task(such as carrying large pipes or heavy cables), a drag chain need be equipped with the high strength I type support plate(integral type);
(2) In case that the dimension of the pipe/cable joint is larger than the support plate inner hole’s diameter or the pipe is subject to frequent dismount, the II type support plate(split type) is preferable;
(3) If used for multiple types of pipes/cables, the cable chain could be equipped with III type support plate(frame type);
4. The width of support plate B1 is determined by the quantity of pipes/cables, helping figure out the width of drag chain B;
5. For applications in which support plate with steel belt is a necessity, please inform us of your requirement specially;
6. Additional Chainplates: as the length of support plate is limited, a wide drag chain could be equipped with an additional or more chain boards. A narrow chain will be more stable if equipped with one morechainplate. Meanwhile, a third chain board could separate the pipe casing and the pipe/cable.(note: parameters of TLG: D,23, e and TL: f, j, k.)
7. Elasticity of Hydraulic Tubing: please be noted that the hydraulic tubing will extend or shrink under certain pressures. Therefore, the elasticity of the pipe need be considered especially when the pressure is high and the drag chain is long.
