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, have good elasticity, have strong adaptability, have low cost, and should be versatile and interchangeable, and 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.
