Product Introduction
Type VI elastic clip fastener is applicable to ballasted tracks with shouldered prestressed concrete sleepers where 60kg/m or 75kg/m rails are laid. The minimum curve radius is not less than 400m, and the maximum axle load is 25~30t.
The VI type fasteners can meet the following lines and operating conditions:
The minimum curve radius is 400 m.
The maximum train axle weight is 30 t, and the maximum speed is 120 km/h.
Fastener Parts: The type IV elastic clip fastener system is a buckle system for a shoulderless track rail. The fastener system consists of a C4 rail clip (joint JA, JB elastic bar), a type IV embedded rail shoulder, an insulation gauge block, and rubber rail pad.
