The towline body by the chain pull (high-quality steel plate chrome) support pull (squeeze pull aluminum alloy) the shaft pins (alloy steel) components, so that the relative motion between the pipe and the towline cable or rubber, does not produce distorted, pull chain chrome-plated handle shape effect novel structure reasonable, smart, high strength, steel is really deformed, easy to install, reliable to use, easy to assemble, in particular, is the use of high-strength wear-resistant materials, alloy copper axis pin, to improve the product abrasion strength, bending more flexible, less resistance, reduced noise, and thus can ensure the long-term use is not deformed, does not sag. 1. The towline can adapt to the maximum moving speed of 40 m / min. 2. Towline maximum moving speed, the sound pressure level of not more than 68 decibels. 3. The towline security service life of not less than 100 million times (back and forth). Tel :0317 -63,412,006,347,666 URL: www.hb-cyfj.com
