Railway rail clamps, also known as rail clamps or rail fixing clamps, are devices used to maintain the horizontal position of rails, especially crane rails, but allow necessary longitudinal movement.
In the rail fastening system, the rail clamp is mechanically locked to fix the rail in place, and at the same time, the longitudinal movement of the rail is accepted by the combined vulcanized and bonded synthetic elastomer nose. Usually, the rail clamp is always fixed to the sleeper with anchor bolts.
In terms of types, the main varieties of railway rail clamps are bolted rail clamps and welded rail clamps.
Railway Rail Clamps Specifications:
Material: Q235-forged, ZG35-cast steel, QT500-7-cast iron
Standards: GB, DIN, ISO, ANSI/ASTM, B7, BS, JIS, etc.
Surface: plain color, black spray paint or according to customer requirements
Packing: woven bag/barrel and pallet/wooden box or customer
Advantages of Railway Rail Clamps:
1. Reduce rail stress through wider contact points
2. Positive pre-torque angle to eliminate bolt bending
3. Fast installation
4. Rugged and durable products with long service life
Types of Railway Rail Clamps:
1. Crane Clamp 21/050 AN/BN:
Crane clamps enable the rails to be installed with good tolerances, and they can be adjusted to ensure precise alignment of the rails. Our clamps are designed to carry heavy loads transferred by cranes to the rails. For the installation method, it can be bolted or welded, depending on the needs of the end user.
2. Crane rail calmps 22/130 AN/BN
The self-locking Gantrail rail clamp is a special design that fixes the rail with a rubber nose. By adjusting the height of the rubber nose, this clamp can be used for different rail types.
3. KPO rail clamp
It is a high-strength bolted railway clamp. KPO3, KPO6, KPO9 are combined with ribbed backing plates, rail bolts and washers, and are more widely used in rail fastening systems.
4. Other fixtures
1) MTH rail clamp
2) K-shaped rail clamp
3) North African rail clamp
