Hebei coal mine turnout _ Xin Yang Machinery (certified) _ coal mine turnout provided by the Forest City Xin Yang Machinery Industrial Co., Ltd. Forest City Xin Yang Machinery Industry Co., Ltd. (www.lzxyjx.com) is specialized in the "tub, turnout," the enterprise, the company of "honesty, hard service" concept, to provide you with the highest quality products and services. Welcome to inquire! Contact: Li. Because of the angle between the center rail itself, the heart creeping influence turnout rail locking and unlocking the power of force. When the heart center rail track crawl due to thickening of the coal mine at the base rail turnouts, is bound to increase the force of locking and unlocking of turnout coal mine company, but can cause serious crawl first traction point locking rod and iron dovetail lock connection occurred mill cards, prone to poor turnout pulled fault; on the contrary when the heart rail back crawl, is bound to reduce the force of tight, prone to failure bayonet while crawling backwards serious cause heart rail traction point second drawing board vertical distance between the iron and the outer locking lever becomes smaller even Jisi wholesale coal mine turnout, turnout can not make normal flip. Renovation of existing lines with Turnouts is still used in the double switch rail track within the framework of the basic structure of the conversion. In addition to the basic framework of the tip rail track between the two sections of tight vertical load to bear turnout manufacturers outside the coal mine, still within the full length of the tip rail wheel-rail interaction withstand the horizontal forces. The basic process with standard gauge rail track in the tip section of tight under the rail head palate as 1: 4 or 1: 3 miter, with a sharp tip rail corresponding cross-sectional structure of Tibetan architecture, in order to improve security and strengthen the sharp reverse operation track section near the tip.
