CM-C Type Tram Rail Fastening

Adjustable Tram Rail Fastener is used For large rail elevation adjustments, auxiliary shims are adopted to preserve the elastic bar's clamping state, ensuring system stability and safety.

The non-metallic baseplate provides corrosion resistance and electrical insulation after backfilling, with strength comparable to steel tie plates.

59r2 / 60r2 Tram Rail Fastening’s enlarged rail-bearing surface reduces vertical pressure on the subgrade, mitigating dynamic impact on the track foundation.

MATERIAL COMPOSITION

The Tram Track Fastening System uses four main components:

A polymer composite baseplate that resists moisture and corrosion

A microporous elastic pad that provides vibration damping

Glass-fiber-reinforced gauge bushings that resist creep and wear

Metal parts manufactured to railway fastener standards

All materials are selected for outdoor exposure, temperature cycling, and long-term load bearing.

Key benefits

Adjustment Reliability

When substantial rail elevation is required, the tram track fastening system utilises dedicated levelling shims as auxiliary aids. This measure ensures that the pre set clamping force and deflection angle of the elastic bar remain undisturbed throughout the adjustment process. Consequently, the fastening assembly retains its intended mechanical behaviour, and the overall system operates with enhanced stability and safety over prolonged service periods.

Ventilation Holes for Monolithic Bonding

Strategically positioned vent holes are cast into the baseplate. During in situ track bed concreting, these openings enable fresh concrete to flow freely beneath the baseplate, eliminating voids and ensuring full interfacial contact. Upon curing, the baseplate becomes monolithically integrated with the surrounding concrete mass, significantly restricting relative displacement of the fastening system under repetitive traininduced forces.

Standardised Metallic Fasteners

The fastening system incorporates only three categories of metallic components: screw spikes, flat washers, and elastic bars. All are procured in strict compliance with Chinese railway industry standards (Tie biao products), whose specifications are mature and extensively validated in both heavy haul and passenger dedicated lines. Their standardised dimensions ensure ready availability, straightforward replacement, and high interchangeability with existing infrastructure.

Baseplate Material and Structural Advantages

The baseplate of Grooved Rail Fastener is fabricated from a high performance non metallic composite. After track bed backfilling, it offers dependable corrosion protection and maintains electrical insulation between the rail and the substructure—critical for stray current mitigation in electrified lines. Tram Track Fastener’s load bearing capacity and flexural strength are fully comparable to those of conventional steel tie plates, eliminating any structural compromise. Furthermore, the baseplate incorporates a generously proportioned railbearing surface. This enlarged contact area effectively disperses vertical wheel loads, reducing the unit pressure transmitted to the underlying subgrade and attenuating the dynamic shocks that would otherwise accelerate foundation deterioration.

Advanced Anti corrosion Treatment

All exposed metal parts are coated using either Dacromet or zinc nickel co permeation technology. These coatings form a dense, sacrificial barrier that exhibits outstanding resistance to humid thermal cycling, acidic and alkaline chemical attack, and atmospheric corrosion. This surface engineering approach substantially prolongs the maintenance interval and overall service life of the fastening system, even when deployed in tunnels, coastal regions, or industrial environments with aggressive pollutants.

Quality Assurance

Before leaving our factory, the ballast mats will be tested strictly according to standard requirements .

For customers who require more, we carry out type tests at our in-house testing centre.

Custom Mould Design & Manufacturing

– In-House, Start to Finish

Our Mould Engineering Department operates a full digital workshop equipped with more than 20 CNC machines, including machining centres, spark eroders, and wire cutters. This allows us to design and manufacture a wide range of moulds for the rail transit industry – injection moulding, rubber, SMC, and specialised types such as auto-core-pulling bush moulds.

Annual output stands at 300 sets of moulds and tooling.

If your project calls for a non-standard shape for Elastic Ballast Mat, a special material, or a unique production feature, we have the equipment and the experience to deliver.
