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.
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 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.
I-beam, a long steel section shaped like the capital letter “I,” is also commonly referred to as a steel beam. Its English name is Universal Beam. This type of steel section can be categorized into ordinary I-beams and light I-beams, both featuring an I-shaped cross-section. In addition, there is a wide-flange I-beam, also known as an H-beam. The H-beam is characterized by parallel flanges with no internal taper, making it an economical cross-sectional steel often manufactured using a universal rolling mill. For this reason, it is also referred to as a “universal I-beam.” Currently, both ordinary and light I-beams are regulated by national standards.
