During shipbuilding and the operation of lifting equipment at large shipyards, rail systems must withstand significant crane wheel loads, dynamic loads, and forces generated by equipment startup and braking over extended periods. At the same time, corrosive factors such as salt spray, humidity, and the marine environment place higher demands on the protective performance of … Read more
The rail gouging may appear to be a “clash” between the wheel and the rail, but the root cause does not necessarily lie with the wheel itself. Wheel flange rubbing is typically not caused by a defect in the wheel itself, but rather by deviations in track straightness and gauge, misalignment of the wheel, asynchronous … Read more
In certain light-duty crane systems, equipment guidance applications, and temporary material handling scenarios, square and flat steel bar rail can serve as alternatives to crane rails. However, their suitability depends on wheel load, wheel-to-rail contact conditions, the support structure, and the frequency of equipment operation. Unlike standard QU crane rails and DIN 536 crane rails, … Read more
China’s Ministry of Industry and Information Technology has officially released the YB/T 5055-2025 standard [Source: MIIT Announcement No. 20 of 2025]. As a brand-new, updated standard for QU crane rails, this standard fully replaced the previous version (YB/T 5055-2014) on March 1, 2026. This engineering technical guide provides expert answers to key concerns regarding wheel-rail … Read more
Where and When Do Crane Rails Need Corrosion Protection? Crane rails used in ports, shipyards, steel mills, mines, and outdoor material handling systems may be exposed to corrosive environments—such as high humidity, rainfall, salt-laden air, and chemical agents—for extended periods. Therefore, an appropriate crane rail corrosion protection solution must be determined based on the operating … Read more
Every year, railway operators worldwide lose millions of dollars due to premature rail track failure caused by corrosion. Although rust and oxidation are common in our daily lives, corrosion on railway tracks is a critical safety hazard that cannot be ignored. When this chemical reaction affects the rails, it directly threatens the structural integrity of … Read more
The hoisting mechanism of the tower crane lifts materials by winding and releasing the wire rope through the drum, and the use of folded wire drum can improve the arrangement of multi-layer wire rope on the drum and prolong the service life of the wire rope. However, if the drum is not set up properly … Read more
In the busy scene of industrial production, cranes are like steel giants, steadily lifting all kinds of heavy loads, and are an indispensable key link in the production chain.The wheel set, as the “legs and feet” of the crane, is directly related to the smoothness and safety of its operation. In the preparation process, you … Read more
Crane hook is a very critical component in lifting machinery, usually classified according to the materials used, manufacturing process, use and other factors.Different types of crane hooks may have different shapes, manufacturing processes, operating methods or other characteristics. Different types of crane hooks are usually capable of meeting different usage needs, load ratings, size and … Read more
Crane drum as a result of frequent use, coupled with the environment may be more humid, which will cause the phenomenon of rust, this situation not only affects its beauty, but also affects the use of performance.The following is to analyse the reasons for crane drum rust, and understand the rust prevention measures. Reasons for crane drum … Read more
