Description

Rail Fastening

Rail Sleeper Screw
Rail sleeper screw spikes are used to fasten sole plates and ribbed base plates to wooden sleepers. In rail construction with the concrete sleepers, the rail sleeper screw is used in combination with a plastic dowel pressed in the concrete sleeper, indirect or direct fastenings of rails on concrete and wooden sleepers. Characteristically, the sleeper screw thread may only be produced in a hotforming operation.

Rail Spike
A rail spike is a large nail with an offset head that is used to secure rails and base plates to the sleepers in track. The rail spikes are roughly chisel-shaped with a flat-edged point. The spike is driven into the sleeper with the edge against the grain, which gives greater resistance to loosening. The main function of the rail spike is to keep the rail in gauge. Rail dog spikes provide a strong, simple and inexpensive solution to securing rail track.

Railway Bolt
Sticking to our quality first policy, SUYU pays great attention to quality control management. We have been granted ISO9001-2008 certificates and have received the production license of China's Railway Ministry on railway products. We have a full set of inspection instruments to ensure all our railway bolt products are of high quality and up to customers' requirements.

Elastic Rail Clip
We are extremely capable of producing elastic rail clip for any type of toe load and axle load requirements to fix the rails on wooden, steel or concrete sleepers. We offer various elastic rail clip with size steel bar diameter from 12mm to 20mm. We manufacture different types of elastic rail clips with flat toe for broad gauge line, having the toe load from 850kgf to 1100kgf, and are capable of providing any type of toe load and axle load to fix the rails.

Rail Cast Iron Shoulder
Our rail cast iron shoulders include M.C.I. shoulder manufactured from pearlitic malleable iron and S.G.C.I. shoulder manufactured from spheroid graphite iron. We offer two types of iron shoulders. One is Single Stem Iron Shoulder used in pre-stressed concrete ties and the other is Twin Stem Iron Shoulder used in Bi-Block or Twin Block concrete ties.

Rail Anchor
Rail anchor is manufactured in one-piece construction for spring steel or equal, heat-treated and designed to eliminate creepage of track. The rail anchors provide a large bearing surface against both rail base and tie, avoiding undo cutting and wear, thus prolonging the life of wooden ties. The rail anchors are used in 50Kg, 85Kg, 90/91LB, 115RE /136RE, UIC54 and UIC60 rail, and so on.

Rail Tie Plate
Tie plates are generally used to take the load of rail and distribute the load to the sleepers offering proven economies. We manufacture all types of base plates suitable for various rail sections, for use on wooden, steel or concrete sleepers and ballast-less tracks used with elastic fastenings on wooden sleepers and 'K' type fastening system.

Rail Clip
The rail clip is a boltable, adjustable, self-blocking clip with high clip strength. The adjustability is secured by means of the square taper washer. There are types for M16, M20, and M24 fastening material. The rail clip is especially used with crane tracks on a steel girder or on a concrete foundation with a steel sole plate. The height of the railway clip is variable, so there is a suitable clip for virtually every rail type.

Railway Washer
Adhering to our quality first policy, SUYU pays great attention to quality control management. We have been granted ISO9001-2008 certificates and have received the production license of China's Railway Ministry on railway products. We have a full set of inspection instruments to ensure all our railway washer and other rail fastening are of high quality and up to customers' requirements.

Rail Nylon Insulator
We produce E type rail insulator and guide plate for SKL rail fastening and Nabla fastening system. The material we use for rail insulator is PA66, with the color white, dark brown and black. Our rail nylon insulator is used to adjust rail gauge and insulate the rail from ties and clips.

Rail Pad
The rail pad, originally called sole plate, is used when rail is attached to concrete, rather than timber, ties or sleepers. Rail pads function to reduce fatigue cracking of the concrete ties, believed to be driven by impact and vibration from the passing train. It is thought that the rail pads act in two ways: they diminish shock or impact loads by providing compliance, and they reduce (by isolation and perhaps by damping) resonant vibrations.

Rail Plastic Sleeve
Rail plastic sleeve is pressed in concrete sleeper and assembled with sleeper screws, guide plates and rail clip to fix the rail. Our rail plastic sleeve is made using either HDPE or PA66 and the product color is available in white, black and dark brown.

We accept axle orders of small quantity or of demanding complex designs on customized requirements. In addition to the competitive price and good sales service, we also supply quality assurance and timely technical service. Besides, our delivery lead time is short.

Coil Spring
The yield strength and fatigue limit of the material interact with each other. Generally speaking, higher yield strength comes with higher fatigue strength. So, in order to increase the fatigue strength we should try to increase the yield strength of spring material, or to use the material with good yield strength and fatigue limit. For the same material, the coil spring with fine grain structure has higher yield strength than that with coarse grain structure.

Leaf Spring Suspension
With the effort of 50 technicians, SUYU develops diversified axles with different sizes and types that have various applications. Meanwhile, owing to our strict quality control system, the product enjoys high quality and a good reputation all over the world.

Brake Block
Our cast iron brake block enjoys many advantages including hardness, impact strength and so on. It consists of two parts, the cast iron and the steel support. Both the surface and core of the cast iron have the hardness within the range of 197< HB< 255.

When facing subsequent impacts to the brake block or brake shoe, the steel support must remain intact.
