Plastwil KE1/4 MOST system is designed for bridge ballastless track. The KE1/4 MOST type of rail fastening system is dedicated for 60E1 and 49E1 rail, to ensure the required track gauge and rail clamping force, and to limit the rails displacement, relatively to the steel plate of ballastless track. Using anchors from the KE1/2 or KE1/4 system instead of screws, enables the KE1/4 MOST system to be applied to a concrete slab of ballastless track.
The KE1/4 MOST fastening system has been positively tested for compliance with the PN-EN 13481-5:2017 standard, category D.
Characteristics and advantages of the KE1/4 MOST system:
- specially shaped surface of the regulation pad and base plate allows the adjustment of each single base plate in the horizontal direction within ±5 mm from the nominal position (with 1 mm step), which allows the adjustment of the track width within ±10 mm with a 1 mm pitch
- system provides excellent electrical insulation, by using a regulation collar and insulation bushing made of plastic
- regulation of vertical position through the usage of regulation pads
- use of nuts with non-standard size polyamide inserts makes difficulty to dismantle the system, by unauthorized persons
- the possibility of using the additional base plate pads in order to determine the proper static stiffness of the system
