Key Techniques For Railway Fastening System 2

As necessity of placing continuous welded rail track, Railway Fastening System in tubing and ballast must have sufficient anti-creeping resistance. Generally, the larger anti-creeping resistance, the greater welded rail track will be. Therefore it generally utilize railroad clip with larger crimping power to secure railing.
For laying continuous welded Track Spike on the bridge, it always adopts rail fastenings with less anti-creeping resistance. In another word, using rail clip with less crimping force to fasten rail. Besides, Rail Clip should be used with low friction coefficient rail pad.
In sum, the key technique for rail fastening system requires the versatility of rail fastening system. Rail fastening system should installing rail clip with bigger crimping force and installing rail clip with less crimping force.
The rigidity of railroad pad reduction, meaning rail clip have big deformation during train departure. At precisely the exact same time, the front of railing clip have larger dynamic deformation. It's higher demand on flexible land and tiredness property of railroad clip. When low-rigidity railroad pad employed, the vital technique is restrain crimping pressure reduction and fatigue lifetime of railroad clip.

Tension Clamp Is Important

图片
With the increase of the axle load of the railway locomotive and the improvement of the running speed of the train, as well as the development of the urban rail transit and the subway, the Tension Clamp  is also becoming a key link in the continuous development of the track structure, which is concerned by all the countries. In the general line, the need is about buckle pressure, good elastic spring, to meet the needs of heavy-duty, high-speed lines, while in the viaduct track seamless circuit, in order to reduce the interaction between the rail and the bridge, we have to ensure the elasticity that is enough, if the train goes through, the loss of undercover cushion due to compression caused by the buckle pressure is small, and fasteners of  Railway Fastening System  do not loose. Although it is a small public work device, but it is an important part of the track, because of its large demand, about 7000 per kilometer, its reliability is directly related to the safety...

Pay Attention to Rail Plate Base Pad

图片
As an indispensable part of the railway, the  Rail Plate Base Pad  plays an important role on the railway. If it falls off, which will influence the whole  Railway Fastening System  deeply. In the high-speed railway subgrade, the separation of the slab Rail Plate Base Pad will reduce the track strength. This situation means the stiffness and service life of the track will be reduced directly. It causes the rail plate base pad to crack and disconnects from the lug time. The pressure of the top surface of subgrade increases with the length of abscission. Meanwhile, the trend of increasing is becoming more and more obvious.

Do You Know Heavy Haul Rail?

图片
The first International Heavy Haul Congress in 1978 was held in Perth, Australia. Since the establishment of the International Association of Heavy Haul Transport in 1985, the definition of heavy railroads has evolved with heavy loads and advancing with the time. In 2005, the International Association of Heavy Load Associations proposed a new heavy haul railway standard that required to meet at least two of the following three conditions: 1.train traction quality is not less than 8000t 2.vehicle axle in the vehicle reach or exceed 27t 3.The length of the line is not less than 150 km, the annual freight volume is not less than 40 million tons. We support several types of  Rail Fastening System  to meet the different rail's requirements.
