Slide chair lubrication
Slide chairs are critical components of a railway's infrastructure, and lubrication is essential. Traditional lubricants are often applied in large quantities, frequently, and are of an oily consistency, which attracts dirt and contaminants from the surrounding equipment.
These lubricants do not penetrate the switch heel, which is the critical point where the switch blade pivots and where flange back contact from the train wheel can occur due to tight gauge. Rollers have also proven to be ineffective at pushing over the heel section of the switch rail.
Interflon Lube EPR is an extreme pressure dry film transparent coating fortified with MicPol® technology. It is the right product for coating and protecting slide chairs to prevent failure in all weather and environmental conditions. Interflon Lube EPR has been tested and approved by leading railways.
Once the slide chairs have been properly prepared, there is no need to clean further. Recoating is only required once every 4 or 13 weeks, depending on the layout design. This leaves slide chairs clean and easy to inspect for damage and wear. Interflon Lube EPR has also been uniquely developed to be able to be applied in very wet conditions and bond to the surface of a wet slide plate.
For efficiency and worker safety, Interflon lubricant is applied from a special backpack while the worker is standing upright, enabling their peripheral vision at all times. A typical switch length takes one minute to lubricate using this new method, significantly reducing the amount of time spent on the track. Moreover, its dry-coating technology reduces contamination and prevents ice adhesion in winter.
