Rail clamp, also known as railway clamp or rail fixing clamp, is a device used to maintain the horizontal position of the rail, especially the crane rail, but allow the necessary longitudinal movement. Usually, rail clamps are always fixed on the sleepers with rail anchor bolts. In terms of types, the main types are bolted rail clamps and welded rail clamps.
Kingrail Parts can produce various types of rail clamps to meet customer requirements, whether it is used on railway lines, subways or crane rail tracks.
In terms of rail clamp material, according to our previous production experience, forged Q235, cast steel ZG35 and QT500-7 cast iron are the top three.

Types of Rail Clamps:
1. Crane rail clamp 21/050 AN / BN
Crane rail clamps can make rail installations with good tolerances, and they can be adjusted to ensure precise alignment of the rails. At the same time, crane rail clamps must be designed to meet the heavy load of cranes. Crane rail clamps can be bolted or welded
2. Crane clamps 22/130 AN/BN
The self-locking Gantrail crane clamp is a very advanced design, which can use rubber nose to fix the crane rail. By adjusting the height of the rubber nose, these crane clamps can be used for different rail types.
3. KPO rail clamp
KPO rail clamps are high-strength bolted rail clamps. KPO3, KPO6, and KPO9 are the most widely used types of rail fastening systems.
4. North Africa rail clamp
This type of rail clamp is usually used on railway lines or cranes in North Africa.
5. K type rail clamp
6. MTH rail clamp
7. Various special customized rail clamps
