TL series steel drag chains TL series steel drag chains are mainly conSISting of chain plate(top quality stainless steel with chromium plated),suPPOrting board (extruded aluminium alloy) and pinshaft(alloy),etc.There is no relative motions between the cables/rubber hoses and the drag chains,giving no deforming or twists.The chromium plated chain board has very nice-looking apearance 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. 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 68db. 3.The service life of the drag chain shall not be less than 1 million times(reciprocating).
