Product Description
The SKL12 rail clip is also known as the SKL12 tension clamp. The rail fastening system that uses the SKL12 rail clip can be used for wooden sleeper and concrete sleeper. The length of the common SKL12 rail clips is about 200mm and the diameter is about 13mm, but the specific size changes according to the actual application needs. Gnee can customize according to the size of customer needs.
Scope of Applicable to SKL12 Rail Clips
- Type of track: It is suitable for the standard railway line and radius R300M lines, including different types of orbits such as ordinary railways, high -speed railways, and urban rail transit.
- Type of steel rails: It is mainly used for 50, 60kg/m steel rail lines, and can be used with the corresponding rail sleeper and fastening system to ensure the reliable connection between the rail and the sleeper.
- Type of rail sleepers: It can be applied to prestressed concrete sleepers, prestressed wide concrete sleepers, and overall road beds in a straight line, etc.
