Product Introduction
GB crane rails, according to national standards, are a type of rail product with specific geometric shapes and performance indicators, specially designed to provide stable track support for crane trolleys and trolleys. Among the many models, GB QU120 crane rails have a rail head width of 120mm and are made of high-quality manganese steel, which enables them to maintain excellent stability and wear resistance when subjected to huge wheel pressure and frequent impacts.
YB/T 5055-2014 is the current industry standard for crane rails, among which QU120 rails are commonly used specifications for crane rails.
QU120 rails have a special cross-sectional shape, with a rail head tread width of 120mm, and specific standards for the maximum width of the rail head, rail height and rail bottom width. When designing the rolling pass, GNEE RAILWAY RAILWAY fully considers the flow law of metal during the rolling process, and determines the shape, size and matching relationship of each pass through multiple simulations and actual debugging. Ensure the accuracy of the crane rail size so that the rail can better fit the track, increase the stability of crane operation and reduce work risks.

Product Application
Important details of crane rail you may know
QU120 crane rail maintenance is essential during use. Here are some of the main maintenance points:
Track surface inspection: Before work or between work every day, the track surface should be visually inspected to check for signs of wear, abrasions, cracks, deformation or corrosion. Pay special attention to the head and side of the track, which are key areas of contact with the crane wheels and are more prone to problems. If minor wear or abrasions are found, keep records to track their development.
Connection component inspection: Check the connection parts of the track, including track pressure plates, bolts, nuts, etc., for looseness, missing or damage. Whether the fishplates between the tracks are tightly connected, with no gaps or misalignment. If there is any looseness, it should be tightened in time; if there is any damage, the corresponding parts should be replaced immediately to ensure the stability and reliability of the track connection.
Track foundation inspection: Check whether the track foundation has sunk, cracks or damage. This can be judged by observing the ground or foundation structure around the track, and measuring the levelness of the track using tools such as a level. If foundation problems are found, their impact on track operation should be evaluated in time and corresponding repair measures should be taken.
