Synthetic Rail Sleeper

Kebos new-type non-adhesive one-time molding large thickness new material synthetic rail sleeper is made of continuous glass fiber reinforced polyurethane resin foam, with the advantages of low carbon and environmental protection, lightweight and high strength, good marital resistance, easy processing and easy installing etc.

HMFP Composite Material

HMFP (High-strength Mat-reinforced Foamed Polyurethane) is a high-strength alkali-free glass fiber mat-reinforced foamed polyurethane material. It has the advantages of light weight, high strength, good weather resistance, easy processing, flame retardant, and the specifications can be customized etc..

Track Bed Damping Pad

The product structure of rubber track bed damping pad is a long cushion with a nail post structure on one side, and its flat plate part is composed of fabric reinforced rubber.

Polyurethane track bed damping pad

Polyurethane track bed damping pad adopt adjustable foaming polyurethane system and elastic bubble hole vibration damping technology to achieve a vibration damping effect of more than 12dB in track system.

Composite Material Evacuation Platform

Evacuation platforms are constructed along the side of subway line, so that in case of fire, traffic breakdown and other emergencies, passengers can reach the refuge area or tunnel exit through the evacuation platform and wait for rescue.

Upper Self-locking (Third Generation) Double-layer Non-linear Vibration Damping Fasteners

Upper self-locking (Third generation) double-layer non-linear vibration damping fasteners adopt elastic snap type upper locking structure. The overall technology is mature and reliable, and its vibration damping effect is up to 8dB or more, it is a typical representative of medium vibration-damping fasteners.

Double-Layer Nonlinear Vibration Reduction Fastener With Shoulders

The Double-Layer Nonlinear Vibration Reduction Fastener With Shoulders is medium and high vibration damping fasteners designed with self-locking structure of the shoulder part. The fasteners have large transverse stiffness, good safety stability performance and low installation height. They are the mainstream solutions for the medium vibration damping fasteners in China.

FST Type High Torsion Resistance High Vibration Damping

FST type high torsion resistance vibration-damping fastener adopts rail suspension structure and wedge self-locking structure, which solves the problem of traditional suspension fasteners, and the vibration-damping effect reaches more than 10dB.

Turnout Vibration Damping Fastener

Double-layer removable turnout vibration damping fastener belongs to medium vibration damping fasteners. Compared with ordinary turnout fasteners, the vibration damping improved more than 8dB.

Rail Damper

KZN rail damper is a kind of rail damping and noise reduction system, fixed on both sides of rail waist, which can effectively attenuate rail vibration and reduce noise radiation caused by wheel-rail impact, and can be applied to underground lines, elevated lines, bridges, whole beds, gravel beds and other lines.
