Type II Fastening System

Spring bar type Ⅲ fastener is a shoulder less fastener, boasting advantages such as high clamping force and good elasticity. It mainly consists of TypeⅢ elastic clips, insulated gauge blocks, bolts, flat washers, heavy duty spring washers, gauge adjusting ,steel sleepers, under steel sleeper pads, nylon sleeves, etc.

Scope of Application

Type II clip fastenings are used to connect 60 kg/m rails to concrete sleepers on standard gauge railways with straight sections and curves having a radius of no less than 300 meters, with a maximum adjustment height of 10 mm.

Type I fastenings and Type II fastenings are elastic fastenings developed with the application of concrete sleepers and the laying of continuous welded rail lines. They are currently widely used on rail lines. This fastening consists of rail clips, screw spikes, gauge plates, plate seats, rubber pads, etc. Concrete sleepers are equipped with shoulder plates, and the fastening is bolted. Similarly, spiral spikes anchored in the concrete sleeper secure the clip to clamp the rail. The clip adopts an Ω shape, with gauge plates and plate seats cooperating to adjust the gauge. To accommodate large adjustment requirements, the Type I height-adjustable clip was developed. Type I and II clip fastenings are suitable for tracks using 60 kg/m rails laid as continuous welded rail. Type I clip fastenings are also applicable for tracks using 50 kg/m rails.

Type II Clip Fastening System primarily consists of spring clips, screw spikes, nuts, flat washers, gauge plates, plate seats, and rubber pads.
