railfastening

In the course of work, such as high-speed rail, heavy rail, subway and light rail, some railway maintenance personnel will find that the  Track Bolt  sometimes is break. The ordinary people do not know why it is. Improper handling of staff affects the  Railway Fastening System . When assembling the tightening torque is too large, with uneven force. Many people believe that the bolt is as tight as possible, but if the torque is greater than the yield limit of the bolt material, the connecting rod bolt will yield its deformation and break under excessive load due to the impact load. High speed rail, rail, subway, light rail fastener fastener installation personnel, must according to the standard bolt tightening rod. Do not be in superstitious belief of more tight, bigger and better strength.

Work fatigue or impact fracture damages  Railway Fastening System . High speed rail, rail, subway, light rail fastener are damaged every day by all kinds of vibration and impact brought by the high-speed train in the work, with the passage of time, the fatigue life will reach the final fracture. In the work, the fastener under the influence of axial force, the thread is broken, the bolt is hurt. The fastener under radial force is bolted and the bolt hole is cut into an ellipse. These are some of the common fracture cases. Rail fastening material problems, or with processing defects and heat treatment problems, which will lead to high-speed rail, heavy rail, subway, light rail fastening bolts broken. To avoid such problems, it is better to cooperate with good quality  Railway Fastening System Supplier  to reduce the rate of defective products or to examine them carefully before use.

With the rapid development of China's high-speed rail, heavy rail, subway and light rail, it has provided a large number of fasteners for different regions and countries at home and abroad.  Railway Fastening System  industry, as the basic industry of industrial production, supports the prosperity and construction of China and the world economy.  High Speed Fastening , or other types of fastening system are important components used to connect the steel rail, if they have problems, it will affect the normal operation of the railway system, so the quality of fasteners is important for railway track.

1. Light Rail Joint Plate is also known as plywood. Heavy rail joint plate, is also known as lifting rail joints plywood. Insulated fishtail board is made of insulating material. Insulated fishtail plate is a new type of track material made of high strength composite material. It has good corrosion-resistant, rust-proof, UV-resistant, non-conductive, non-magnetic. Belonging to the thermosetting material, it can not be secondary processing, so does not afraid of stealing. 2. Rail joint plate can be divided into 8kg, 12kg, 15kg, 18kg, 22kg, 24kg, 30kg, 38kg, 43kg, 50kg, 60kg, 75kg according to the rail. Insulated light rail joint plate includes 8KG,9KG,12KG,15KG,18KG,22KG,24KG,30KG.It is also known as splint, insulated heavy rail fish tail plate 38KG,43KG,50KG,60KG,QU70,QU80,QU100,QU120, also is known as lifting rails. We provide the whole Railway Fastening System, if you need, please contact us.

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.

Train tracks require frequent repairs and overhaul to ensure train safely drive, smoothly, at the required speed. Compare with in overload transport conditions under the track and the general track, from abroad, it bears the axle load from the original 10 tons to 25 tons, or even to 35tons.The whole train traction lifting weight increases from the original more than 1,000 tons to tens of thousands of tons, which aggravates the damage of track parts, the accumulation of residual deformation of the track bed, seriously affects the traffic safety. Heavy haul railways require special  Railway Fastening System s, so we develop the special product such as  Heavy Haul Fastening .

Towards the railway line there are such a group of people, they are carrying twenty even thirty kilograms of tools every day, they walk ten kilometers of stone road, ignore all the rain or shine, regardless of day and night, live only with the track and the passing of the train. The ‘patient’ of the patrolman is the rail, for each of the sleeper ‘check the body’ to see if the  Sleeper Screw  is loose, ensure the railway line is faulty, they are railway patrols guarding railroad, responsible for checking the railway line, and correctly handle the fault, to ensure that each deviation of the sleeper no more than 1 mm, to ensure the smooth passage of the train. On rail transport line, it is only these ordinary patrol workers just like the ordinary sleeper, do they ensure the safe operation of each train. Thanks to those people who maintain  Railway Fastening System  every day.
