Steel towline, general applications in machine tools, cables, tubing, trachea, plumbing, duct, from the traction and protection role. The use of steel towline originated in Germany, later domestic references and innovative structure. Steel towline has been widely used in the machine to protect the cables, etc. so that the machine as a whole look more beautiful. Towline, rectangular metal hose, protective cover, bellows, plastic coated metal hose belonging to the cable protection products. Steel towline towline based on the use of the environment and different application requirements, divided into the bridge steel, fully enclosed steel towline, semi-enclosed steel towline three. TL Department of steel towline main chain pull (high quality steel chrome plated) to support the pull (crowded pull aluminum) shaft pins (alloy steel) and other components, so that does not produce the relative motion between the cable or rubber tube with towline does not produce distortion, chain pull the chrome handle shape effect novel reasonable structure, high strength, dexterity, the steel is better deformation, easy installation, the use of reliable, easy to assemble, especially high-strength wear-resistant material, copper alloy axis pin. to improve the abrasion resistance of the product, the bending is more flexible, less resistance, lower noise, which can guarantee long-term use does not distort, does not sag. Towline can adapt to the maximum moving speed of 40 m / min. Two. Towline when the maximum moving speed, the sound pressure level is not greater than 68 db. 3. The towline safety of life is not less than 1 
 000 000 (reciprocating). Steel towline specifications 45,65,95,125,180,225,250 of type, the towline width can be customized to user requirements, the bending radius from 50-800. There are three support plate form. (1) When the towline carrying a larger pipe, cable load should be used in high-strength support plates - one-piece (2) pipe fittings cable size is greater than the cavity aperture of the support plate or require frequent disassembly maintenance and so on. Support plate - can be used to separate (3) installation of umbilicals specifications varieties more, the choice of the support plate - frame steel towline use must pay attention to the following: .1. The TLG and TL 
 For steel towline to use travel a maximum of 
 40 m in all modes of transmission. Can be lengthened and shortened. In addition, by changing the pin to change the bending radius. Bending radius according to the maximum diameter of the cable and should reach the diameter of the cable 10 
 Times, the trip may be to select the smaller the radius of steel and aluminum towline towline support plate width from 150mm to 
 800mm, the interval between the hole and the hole is 10mm. The height of the chain plate to support the height of the board, is determined by the maximum diameter of cable. 3. Machine to do the maximum operation, such as the width of the steel towline more than 
 300mm, the length of the towline more than 4m for stability reasons, you should consider options to increase on the 1st Specification of towline.
