The TL series towline main chain plate (high quality steel chrome-plated) support plate (aluminum) squeeze pull of shaft pins (alloy steel) and other components, so that does not produce the relative motion between the cable or rubber tube with towline not produce distorted, and the chain plate, chrome plated novel effect of shape, reasonable structure, nimble, high strength, steel is no better deformation, easy installation, the use of reliable, easy disassembly, in particular, this product uses high-strength wear-resistant materials alloy axis pin to improve the abrasion resistance of the product more flexible bending resistance is smaller, reducing the noise, which can guarantee a long time does not distort, does not sag. This product is beautiful, beautiful appearance to a greater extent to enhance the overall artistic aesthetic effect of the machine tool equipment, and enhance the competitiveness of China's machine tools, machinery and equipment in the international market. 1, the towline can be adapted to the Maximum certain speed 40 m / min. 2, the towline when the maximum moving speed, the noise sound pressure level is not greater than 68 db. 3, the the towline security service life not less than one million times (reciprocating). Towline need to carry a larger tube, the cable load, should be used in high strength support plates - one-piece pipe fittings cable size is greater than the support plate cavity aperture or require frequent disassembly, repair, can be used to support board - separate type. More varieties of umbilicals installation specifications, the choice of the support plate - cabinet rack.
