The Rail Fastening System with Tension Clamp Skl 12

Frictional tensioning of the rail is achieved using two tension clamps, each offering a tensioning force of approximately 13 Kn through the spring arms. The centre loop of tension clamp Skl 12 serves to protect the rail against tipping. The rail fastenings can be pre-assembled on the sleeper at the sleeper factory. The superstructure with tension clamps Skl 12 is applied on steel sleepers by welding ribbed plated onto the sleeper.
