Rail clip/rail clamp plate
Rail clamp (rail clip) is a component that ensures that the rails are properly fixed to the ground. Rail clips undertake rail movements synchronously thanks to the synthetic elastomer vulcanized to clip permanently in the portion to be contacted with rail.

The Role of Rail Clamp in Rail Fastening System
KPO Rail Clamp
Railroad clamps, other names are rail clip or rail fixing clip, is kind of device to be fixed on tracks to prevent the train from moving or passing a given point to the ground (as at platforms or on stub tracks) to avoid accidents. Rail clamps have basic features of boltable, self-locking, adjustable with fine tolerance and high clip strength.
Railroad rail fasteners are parts of the rails used to join rails and sleepers (or other types of rail underlays), also known as intermediate link part. Its function is to fix the rail on the sleeper, maintain the gauge and prevent the rail from moving longitudinally and laterally relative to the sleeper. Railroad rail fastening system is divided into: shrapnel fastener system, Clamp(buckle) fastener system, elastic fastener system.

YONGYANG supplies customer with wide range of railroad clamps, which has been used in railroad construction and has proved its top class and durability. Our railroad clamps is fabricated using high grade steel and designed according to parameter of industry and market demands. YONGYANG is able to produce according to your drawing.
Rail Clamps Types:
- Crane Clamp 21/050 AN/BN:
Crane clamps enable the rails to be installed with good tolerances, with them adjustable to ensure the rails' precise alignment. Our clamps are designed to carry the heavy load which cranes pass to the rails. For installation methods, it can be bolted or welded, up to the end users' needs.
- Crane clamp 22/130 AN/BN
Gantrail rail clamps of self locking is a special design to secure and fix the rails with a rubber nose. Such clamps can be used in different rail types through adjusting the height of the rubber nose.
- KPO rail clamp
It is kind of boltable clip with high strength. KPO3, KPO6, KPO9 are more popular used in rail fastening systems, by combining with ribbed tie plates, rail bolts and washers.HuiBo Railway also produce and supply "K" and "MTH" type Rail Clamps as well as some Clamps for North African Railway .

Rail Clamp Application History
Clamp fastener system is a kind of rail fastener system. It belongs to rigid fastener. At present, there are several types of rail clamps, the fasteners used in China's concrete sleeper are not separated, except for the early development of the bolt buckle plate type, 63 and 70 Clamp fastener system are rigid fasteners, the others are elastic fasteners.
At the time, there was no sulfur anchoring technology. Only the wooden bolster was embedded in the concrete pillow and the bolted spike was screwed in to connect the fastener with the sleeper. The type 70 buckle is a shoulder type and is suitable for rails of 50 and 43 kg/m. The rail can be adjusted by pressing the rail with a buckle plate and changing the number of the buckle. The connection between the spiral spike and the sleeper is in the form of a sulfur anchor.
