Precautions for crane running in period operation

What should be noted during the break in period when using a crane? Next, let's follow the editor of the Shandong gantry crane manufacturer to take a look at the introduction of this article.

1. Control the number of operational errors. Due to insufficient understanding of the structure and performance of cranes, it is easy to cause malfunctions and even mechanical accidents due to operational errors.

2. Avoid poor lubrication. Due to the small fit clearance of newly assembled components and the difficulty in ensuring the uniformity of fit clearance due to assembly and other reasons, lubricating oil is not easy to form a uniform oil film on the friction surface to prevent wear. This reduces lubrication efficiency and causes early abnormal wear of the components. In severe cases, it can cause scratches or biting on the mating friction surface, leading to the occurrence of faults.

3. Prevent leakage. Due to looseness, vibration, and heating of the machine, the sealing surfaces of the machine and pipe joints may leak; Some casting and processing defects are difficult to detect during assembly and debugging, but due to vibration and impact during operation, this defect is exposed and manifested as oil leakage. Therefore, leaks are likely to occur during the break in period.

4. Wear rate. Due to factors such as processing, assembly, and adjustment of new components, the friction surface of the crane is rough, the contact area of the mating surface is small, and the surface pressure is uneven. During the operation of the machine, the concave and convex parts on the surface of the parts rub against each other, and the falling metal fragments continue to participate in the friction as abrasives, accelerating the wear of the mating surfaces of the parts. Therefore, during the running in process, it is easy to cause parts wear, and the wear rate is fast. At this point, if overloaded, it may cause damage to the parts and result in early failures.

5. Regularly check to avoid looseness. The newly processed parts have deviations in geometric dimensions and fitting dimensions. In the early stages of use, due to the influence of alternating loads such as impact and vibration, as well as the effects of heat and deformation, and excessive wear, it is easy for the originally fastened parts to loosen.
