Disadvantages of railway bolt manufacturers: Rail joints are one of the three weak links in the track structure. They are the main reason for long-term troubles to improve the speed and quality of the lines. They are the focus of daily maintenance in the public works department. The maintenance and repair work of the joints accounts for the track. 60% of the maintenance workload.
 The disease of the rail joints has aggravated the usual track inspection rate and the obvious shaking of the additional ride. The most fundamental reason for the occurrence of rail joint diseases is the discontinuity in the track structure and the unevenness of the rail surface in the rail joint, which leads to the generation of greater additional power between the wheel and the rail.
The excessively large additional power effect promotes the development of discontinuity and irregularity and the increase of additional power, which also promotes the development of joint diseases. In addition, improper maintenance methods will promote the occurrence and development of joint diseases.
Due to repeated ramming of the joint, the standard is not high, the formed joint ends are unevenly soft and hard, the rail seam is too large, the joint bolt torque is insufficient, the joint height, and the left and right teeth are wrong. Under the impact of the train wheelset, the joint rail is caused. Loss of block, sleeper crack failure, splint damage increased. As a result, the maintenance cycle of the joint is shortened, the labor intensity of the line personnel is increased, and the unsafe factor is left to the railway transportation.
Railway bolts manufacturers must always implement the "safety first, prevention first" policy, and strictly implement the "sunroof repair" system. Give full play to the work efficiency of manpower and machinery in the sunroof points as our daily operating standards, and truly achieve "driving No construction, no construction works." Strictly "prevention first, combination of prevention and treatment, equal attention to training" is the principle of line maintenance work implemented in the operation, so that the train can run safely, smoothly and uninterrupted at the specified speed, and maximize the service life of the equipment.https://www.ydfastener.com/products/railway-bolts/
