Product Introduction
The railway fastener system is a set of fastening devices designed specifically for railway tracks. It consists of spring clip fasteners, rail pads, anchor bolts, flat washers, etc. It can be divided into spring clip insertion type and bolt fastening type according to the installation method. The spring clip insertion type fastener system is easy to install and efficient, and is suitable for large-scale railway construction; the bolt fastening type has higher fastening reliability and is often used in key parts of railways, such as bridges, tunnel entrances and exits, and other areas with strict requirements on track stability to ensure the safe passage of trains.
Nabla Clip Rail Fastening System plays an indispensable role in the construction and maintenance of railway tracks. The Nabla clips in the system are manufactured through standard production processes and can accurately fit the rails to achieve efficient and stable fastening. The insulation function of the insulator effectively isolates the current and prevents electrical failures. The various components are tightly connected by high-strength bolts, nuts and washers. In conjunction with the ballast bed of ballasted track or the elastic cushion of ballastless track, they can effectively disperse the train load, reduce track deformation, and extend the service life of the track, providing a solid guarantee for the efficiency and safety of railway transportation.
