Industry knowledge
Elastic rail clip is one of the common railway fasteners in the railway system. In general, elastic rail clip is made of forged spring steel and has many applications. No matter as a part of rail fastening system or as a rail fastener, elastic rail clip is used with other railway track parts, such as railroad spike, rail pad, tie plate and plastic dowel.
Rail clip types
For different applications and national standards, elastic rail clips can be classified into various types, including rail e- clip, SKL rail clips, Nabla rail clip, Deenik clip, crane rail clip, Russia rail clip as well as other standard rail clips.
E-type rail clip
E rail clip provide positive and durable rail alignment under the harshest working conditions, which extend the life of railway track. Generally, e rail clips are available at the range from 18mm to 23mm diameter. Rail –e clip is usually made of spring steel. As an important type of elastic rail clips, E-rail clip has a lot of sizes, such as E1, E2, E3, E1609, E1809, E1817, E2001, E2006, E2009, E2055, E2056, etc.

SKL rail clip
SKL rail clip, also called skl tension clamp. German railway is the first to develop SKL elastic rail clips. And then, they are proved to be reliable on the concrete and wooden railroad ties. SKL rail clip include many sizes, such as skl1, skl3, skl12, skl14, and etc.
