High Speed ??Turnout construction technology | Xin Yang Machinery (certified) | Shandong Expressway turnout by Lin Xin Yang Machinery Industry Co., Ltd. Taizhou. 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. Since there are single turnout (single turnout), there are double turnout (equilateral turnout), three turnout (three-way turnout), and multi-turnout (Double Slip Switches) and so on. Turnout for the Y-shaped double-speed turnout position that dovetail with the turnout of the two sides share the road bifurcation. Three turnout as Ψ shape what is high-speed turnouts, while convergence of three strands Road, by two sets of mechanical manipulation derailleur tip rail. Double Slip Switches like X-shaped, in fact, equivalent to four single turnout and a diamond cross combination. Improve the strength and reliability of the guard rail. There Groove guard rail and H type two. Groove guard rail which uses channel No. U1C33 manufactures high-speed Turnout construction technology, H-type guard rail with a low-level rail manufacturing (eg 60kg / m of frog guard rail with 50kg / m rail manufacturing). For t improve safety guard rail at high speed driving turnout, guard rail of the top rail of the top higher than the basic 12mm. Turnout fastener strength than the "75" model has improved greatly. For example the use of wedge adjustable rail brace, rigid split-arc plate buckle fasteners, threaded portion of the guide curve spike, spike, and so cancel hook.
