Steel Drag Chain (Steel Cable Drag Chain), commonly used in machine tools machinery such as cable, tubing, the trachea, water pipe, air duct, traction and protection.Now the steel drag chain (Steel Cable Drag Chain) has been widely used in machine tools, to protect the cable also make machine overall looks more beautiful.
I. TL series steel drag chains (TL series steel cable drag chains)
TL series drag chains are mainly consisting of chain plate (top quality stainless steel with chromium plated), supporing board (extruded aluminum alloy) and pinshaft (alloy), etc. There is no relative motion between the cables/ rubber hoses and the drag chains, giving no deforming or twists. The chromium plated chain board has very nice-looking appearance and has very rational construction and flexible and high strength. It is reliable and easy to operate, install, dismantal or assemble. It is worthwhile mentioning that the anti-wearing performance has been improved greatly due to wear resistant material and alloy pinshaft are used. The product is flexible to bending and has low resistance, giving low noises. It can be used for a very long period of time without any deformation or hanging down.
The product is nice-looking, which makes the machine tool unit nicer looking as a whole and makes the machine tools and machineries more competitive in the international market.
1. The drag chain can adapt to max moving speed of 40m/sec.
2. When at the max moving speed, the sound pressure of noises shall not be greater than 68 db.
3. The service life of the drag chain shall not be less than 1 million times (reciprocating).
Drag chains with 3 chain board:
One or more drag chain boards can be installed on a wider drag chain, because the max length of the supporting board is 600mm-650mm. This arrangement can also improve the stability of the narrower chains. In this way, the conduit and the cables can be separated from one another by a third chain board.
Elastic status for hydraulic pipes:
Note that the pressure of a hydraulic pipe may extend or contract downward, so the elasticity should be taken into consideration, especially under high pressure or with long length.
II. TLG series steel drag chains (TLG series steel cable drag chains)
There are TLG separate type and TLG frame type.
The TLG type drag chains are suitable for installing a large quantity and heavy duty of cables and oil pipes which allow suspending installation (supporting is not allowed) and is lengthy. The supporting plate can be made according to the user`s requirements. It is suitable for machine tools and moving machines. Their bent radius ranges from 50-600mm and the chain`s height is from 35 to 150mm. Users can make a free selection of them.
The TLG type drag chain has a max travel range of 32 meters and is suitable for all kinds of transmissions. It can freely be made longer or shorter. In addition, the bend radius can be changed by changing the pinshaft.
The width of the supporting board is from 150mm to 600mm. The distance between the holes is 5mm.
The height of the supporting board depends on the max outside diameter of the cables. When the machine tool is working in the highest speed and if the max width of the drag chain is longer than 300mm with the chain`s length longer than 4m, one size larger than normal should be selected just out of consideration of safety.
The bend radius should be selected according to the max diameter of a cable and should be 10 times of the diameter of the cable used. The bend radius can be selected as 50-600mm according to the given table. Small radius should be selected for those ones with small travel range.
Drag chain length=1/2 travel range + 4 bend radius, this is only used for the fixed connection which is located at the middle point of the travel range.
The fexation of the drag chains can be done according to the location of the machine tools. The angle steel can be put in the outer or the inner, in other words, in the inner side of the chains or in the outer side. In common cases, it is in the inner side of the chains and face towards outside.

The TLG type aluminium alloy drag chains are different from the ordinary ones. The can made by using fixed aluminiu shape materials to meet the needs of the users. The width of the supporting board can be 12mm. When operating under high operating speed and high travel speed, the drag chains can be separated from one another so as to ensure the cables being protected in a very safe condition.
TLG aluminum alloy type is the only solution to the larger size chains. The supporting boards can be made according to the requirements of the users. Thanks to the strong construction, the width of the supporting board can be 1200mm.
TLG plastic spacing straps can moved and adjusted in position freely. See figure for details. If cables in many different specifications, you may select this economic device.
