Crane tracks are fundamental components for crane operation, providing a stable running path to ensure that the crane can safely and efficiently complete lifting tasks. 1. Track Safety Inspection: Inspect the tracks, bolts, and clamps for cracks, looseness, or corrosion. If cracks are found, the affected part should be replaced promptly. Other defects should be repaired in a timely manner. The main inspection tool used is a rail flaw detector.
The types of rails are typically classified by their mass per meter. In China, the commonly used rail types on railways include 75 kg/m, 60 kg/m, 50 kg/m, 43 kg/m, and 38 kg/m. These rails all feature an I-beam cross-sectional design, which provides excellent resistance to bending and includes key components such as the rail head.
Light rail: Rails with a weight per meter less than or equal to 30 kg are classified as light rails. Common specifications used in China include 8 kg/m, 12 kg/m, 15 kg/m, 18 kg/m, 22 kg/m, 24 kg/m, and 30 kg/m. These rails are primarily used for transport lines and tracks for light locomotives in locations such as mines, forestry areas, factories, and construction sites.
With the development of China’s economy, the impact on various sectors has been profound, and the central role of railways in resource transportation is beyond question. The experience of some countries shows that the construction and operation of railways can drive the growth of many industries, boost economic prosperity, and gradually become a vital engine for economic development.
Railway rails are used for laying railway tracks, and must withstand the pressure, impact loads, and friction generated during train operations. Therefore, they are required to have sufficient strength and high toughness. The quality standards are strict: in addition to ensuring the appropriate chemical composition, tests on mechanical properties, drop hammer tests, and macrostructure examination using acid etching are also required. According to railway standards, the main types of heavy rails are those weighing 50 kg/m and 60 kg/m.
Railway lines are composed of various railway components, and in order to ensure operational safety, regular inspection and maintenance of these components are necessary. There are many types of railway components, but the main ones that make up the railway track include rails, sleepers (ties), connecting parts, ballast, anti-creep devices, rail braces, and turnouts (switches). As an integrated engineering structure, the track is laid on the roadbed and serves to guide the movement of trains, directly bearing the immense pressure from locomotives, cars, and their loads. Under the dynamic forces generated by train operations, each component must have sufficient strength and stability to ensure that trains can operate safely, smoothly, and continuously at the designated speeds.
