QU70, QU80, QU100, QU120, etc. are sizes of crane rail. QU70 is a specific size of QU crane rail series according to Chinese standard. The number “70” refers to the head width of the crane rail. Thus the QU70 rail head is 70mm wide. Application Crane rail is a special kind of rail track providing …
Crane rail is needed for the crane to work with as a complete system of operating the lifting work. The choose of crane rails and the installation of crane rails must meet the requirements. Then the cranes can play its role efficiently. There are numerous crane rails for sale. It is recommended to buy crane …
Railroad track guides the train to move forward and bear the load at the same time. The flatness of rails is the cornerstone of safe comfort and high-speed running. The friction between the rail and train wheel brings out defects (spalling, shelling, cracking, rail corrugation) and leaves an irregular surface. All these defects on rails …
The railroad track is continuously under force impact from trains in the long-term harsh natural environment. The mechanical wear on the railway line is gradually increasing, and the geometric dimensions of the track, ballast, subgrade and are gradually deformed. Especially the large damage to the track structure and its parts, causing serious railroad track deformation. …
Made of steel, railway track (railroad track in AE) will expand when the temperature rises and contract when it’s cold. When the railway track is exposed to extreme heat, it may buckle. When the ground temperature reaches 37℃, the rail surface temperature can reach about 50℃. Due to the principle of thermal expansion and contraction …
Railway steel or some called rail steel is used for making railroad tracks. Railroad tracks are bearing heavy loads and subject to wear and fatigue. So the grade of railway steel must meet the demands of train speed and load. Proper chemical composition of railway steel enables the rails to have enough hardness and wear …
The railway track is a British express of the tracks on a railway. It is also called railroad track in the United States. Usually, people talk about the railway track as a whole structure including rails, sleepers, fasteners, ballast (or slab track ) and subgrade. The structure can be divided into two parts, the superstructure …
Railroad tracks, also called railroad rails or railway tracks, are essential for railway systems for its function of leading trains move forward and carrying loads then transfer it to the lower structure. With the development of railways in the direction of high-speed and heavy-load, modern requirements for rail quality are getting higher and higher. As …
As we all know, railroad tracks are produced with certain lengths, such as 12.5m, 25m, and the lengthen ones from 50m to 100m. No matter how long the railroad rail is, they need to be joined end to end to make a continuous railroad. This can be realized by rail joints (joint bars) or welding …
Railway track gauge is the distance between the inner faces of the head of two rails. You might be wondering what different types of gauges are currently found around the world? About 60% of the world’s railroad tracks use the standard 1435mm (4 ft 8 1⁄2 in) gauge today. The other 40% use either a narrow gauge or a …
