Descriptions:

The Pandrol Rail Clamp is an innovative temporary rail joint clamp used prior to welding and to safeguard rail defects prior to repair.

The Rail Clamp has been engineered to eliminate many of the disadvantages of other traditional rail clamp designs and provides enhanced performance under all conditions of use.

The Pandrol Rail Clamp design is radically different to the legacy design and guarantees a positive pre-torque angle so as the bolt is tightened the bolt holes remain aligned, eliminating the risk of bent bolts. Pandrol tests have proved that bolts remain straight even at twice the recommended torque.

Technical Features:

Higher clamping force

Increasing the clamping force immediately improved the reduction of rail creep due to temperature change. Reduced rail creep coupled with improved vertical deflection allows networks to operate at higher line speeds over the joint.

Improved safety

The Pandrol Rail Clamp eliminates the risks associated with reduction in clamping force which include vertical rail movement and rail creep.

Advanced design

The design of the clamp geometry ensures self-support of the bending load and reactionary loads are spread and target the rail web, which ensures that the bolt no longer takes bending load.

Engineered to self-align

The self-supporting profile of the clamp aids the installation process; the clamp self-aligns on to the fishplate due to the locking of the two clamp profiles under the rail. This makes it far easier for one person to install the clamps reducing the installation time to less than 2 minutes per clamp.

Compatible with many different rail profiles

The Pandrol Rail Clamp has been designed to accommodate most rail profiles to allow product reuse in most environments.

Reduced friction through wider contact points

To reduce the friction between the clamp and the rail foot the contact points are moved further apart. This reduces the force on the rail and the stress within the edge of the rail foot.

Advantages:

1.     Potential for higher line speeds and lower time-delay penalties.

2.     Proven reduced rail joint creep and improved vertical joint deflection.

3.     Potential for higher allowable line speeds when a longer fish plate is used resulting in reduced rail movement and reduced risk of joint separation.

4.     Clamp geometry enables a greater proportion of the bolt load to be applied to the fish plates.

5.     Reduced vertical rail movement and reduced rail joint creep due to higher clamp load.

6.     Reduction to the installation time due to self-supporting design.

7.     Hardlock anti-loosening nut system available.
