China Manufacturer – Tram Rail Fastening Systems without Sleepers
Tram Rail Fastening Systems without Sleepers adopts universal type II elastic clips as fasteners, universal spikes, universal casings and gauge blocks, which can be poured directly into the trackbed. Through the spikes, the grooved under-rail base plate and the reinforced concrete trackbed form an organic whole, providing reliable support for the trough-shaped rail. The construction procedure is simple, with good flexibility, 20mm gauge adjustment and 20mm height adjustment, which can well adapt to complex line conditions and environmental requirements.
Compared with rail transportation such as national railways and subways, trams have relatively slower speeds and lighter axle loads; the line conditions are complex, the right of way is unclear, and the radius of the tram is relatively small. Its fasteners strive to be simple, have moderate buckling pressure, good elasticity, strong adaptability, low cost, and should be versatile and interchangeable, and are easy to install and maintain. And meet the requirements of insulation and vibration reduction. The AL series fasteners are developed based on the above requirements. Tram Rail Fastening Systems use general-purpose type II elastic clips as fasteners, general-purpose spikes, general-purpose casings, and gauge blocks.
- The advantages of AL series fasteners compared with other urban rail transit fasteners:
- The base plate under the rail is made of high-strength, low-rigidity nylon instead of cast iron and rubber under the iron plate. The manufacturing process is relatively environmentally friendly, with fewer parts, and nylon has good durability, unlike the iron backing plate that has corrosion.
- The insulation performance of the under-rail substrate made of nylon is far greater than that of other fasteners, which protects the under-rail foundation from stray currents.
- Adopt general II-type elastic clips as fastening parts, adopt general spikes, casings, and gauge blocks, which are convenient for installation and maintenance, and has versatility and interchangeability.
- The structure is simple and light, which reduces the labor intensity of workers during paving construction and maintenance.
- The rigidity of the base plate under the rail is much smaller than that of the iron plate, which can reduce vibration and noise.
