what is crane skewing

Cranes are important equipment in the construction industry that are used for lifting heavy loads. One of the important aspects of crane operation is alignment. When cranes are not aligned properly, they can become unstable and unsafe to operate. Crane skewing is one of the alignment issues that can result in crane accidents. In this article, we will discuss what crane skewing is, the causes of crane skewing, and how it can be prevented.

What is crane skewing?

Crane skewing refers to the misalignment of the crane’s tracks or wheels. This can result in the upper structure of the crane leaning in one direction, while the tracks or wheels remain straight. Skewing can cause the crane to become unstable and can result in accidents. Skewing can occur in both mobile and tower cranes.

What are the causes of crane skewing?

There are several causes of crane skewing. One of the main causes is uneven ground conditions. When a crane is set up on a surface that is not level, it can cause the crane to skew. Another cause of skewing is overloading. When a crane is overloaded, it can cause the upper structure to lean in one direction, resulting in skewing. Incorrect outrigger placement is also a cause of skewing. If the outriggers are not placed in the correct position, it can result in uneven weight distribution, causing the crane to skew.

How can crane skewing be prevented?

Preventing crane skewing is essential to ensure the safety of personnel and property on the construction site. One of the ways to prevent skewing is through regular maintenance and inspection of the crane. Inspection should be carried out before and after every use to ensure that all components are functioning correctly. The crane operator should also ensure that the crane is set up on a level surface and that the outriggers are placed in the correct position. Overloading the crane should also be avoided, and the load should always be within the crane’s rated capacity.

Conclusion

In conclusion, crane skewing is a serious issue that can result in crane accidents. It is caused by uneven ground conditions, overloading, and incorrect outrigger placement. To prevent skewing, regular maintenance and inspection are necessary, and the crane should always be set up on a level surface. The crane operator should also avoid overloading the crane and ensure that the load is within the crane’s rated capacity. By following these guidelines, crane skewing can be prevented, resulting in a safer working environment.
