Product Introduction
TheNabla Clamp Railroad Tie Fasteners system achieves a stable connection between rails and sleepers through mechanical fastening. The core components include Nabla springs made of special alloy spring steel, high-insulation engineering plastic insulators and high-strength metal connectors. The system can effectively resist the longitudinal, transverse and vertical forces generated by train operation, prevent rail displacement, and has good electrical insulation performance. Its advantages lie in modular design and high compatibility. It can be adapted to various track structures such as ballasted track and ballastless track, and is listed as the preferred solution for railway projects in many countries.
Nabla Clamp railway tie fastener is an important component used to connect railway sleepers and rails.
Component composition
Nabla clamp: usually made of alloy spring steel such as 60Si2MnA, 60Si2CrA, with a thickness of 4mm or 4.5mm, it is a key component to provide fastening force.
Insulator: used for insulation and support between rails and other components, with a variety of specifications to adapt to different types of rails, such as UIC54, UIC60, 50kg/m rails, 60kg/m rails, etc.
Screw and nut: The screw material is Q235 (4.6 grade), 35# steel (5.6 grade), 45# steel (8.8 grade), etc., and the nut is 35# steel (5 grade), 45# steel (8 grade) and other grades, which can be customized according to needs.
