Type V Railroad Rail Fastening Systems, Rail Fasteners for High-Speed Railway
V Rail Fastening Systems for High-Speed Railway is an elastic track fastener designed to adapt to the laying of prestressed concrete ballasted tracks with shoulder sleepers and to meet the technical requirements of the passenger dedicated line fastener system.
The V Railroad Rail Fastening Systems, Rail Fasteners for High-Speed Railway meets the following operating conditions:
Passenger dedicated line with the maximum speed of 350km/h: axle load of 170kN (considering that axle load may increase by 10%).
The maximum speed of 250km/h passenger dedicated line (taking into account freight): the maximum axle load of passenger cars is 230kN (passenger locomotive); the maximum speed of trucks is 120km/h, and the maximum axle load is 250kN.
From the structural composition point of view, the V Railroad Rail Fastening Systems, Rail Fasteners for High-Speed Railway is mainly composed of screw spikes, flat washers, spring clips, gauge baffles, under-rail pads and embedded dowels. In addition, in order to adjust the rail height, also need to use the height adjustment pad. Before installing the elastic V track fasteners, the workers need to make corresponding preparations. The installation accessories must be complete, remove the mud from the sleeper bearing rail surface and the bottom of the rail, and remove the plastic cover on the embedded dowels.
