1. Anti-climbing device, when the train is running, it usually produces longitudinal force on the rail, resulting in longitudinal movement of the rail, and sometimes even driving the sleeper to move together. This longitudinal motion is called crawling. Crawling generally occurs in the main section of the double-track railway, the direction of the heavy car on the single-track railway, the braking range on the downhill slope and during the station. Line crawling often causes uneven rail joints, tie skew and other phenomena, causing great damage to the line, and even causing the following hazards, such as vehicle derailment on the runway, endangering driving safety. Therefore, we have to take effective measures to prevent crawling, and anti-climbing devices and anti-climbing devices are usually used to prevent the line from crawling.

2. Insulated gauge tie bar, with a cross bar to connect the two rails at the bottom of the rail to improve the lateral stability of the rail and improve the ability of the track to maintain the gauge. Some lines have track circuits separated by insulated sections.

3. The fishtail plate acts as a connection at the joint of the track. A fishplate is a connecting fastener used to connect a track. Compared with rail butt welding technology, the fishplate is less labor and easier to install. The tail plate and the tail bolt are used together. The middle of the tail plate is provided with a screw hole. The upper and lower working face contacting the lower part of the rail head and the lower working face contacting the upper part of the rail bottom are arranged along the upper and lower sides of the horizontal axis of the screw hole. The structure of the fishtail plate is simple, which can reduce the influence of the wheel on the rail joint, increase the continuity of the longitudinal deformation of the rail joint, and improve the ride comfort of the train.

In general, any kind of railway accessories on the railway will be directly related to the safety and stability of the railway. Our company provides a wide variety of railway accessories, models are complete, can meet the needs of users.
