Factors Leading to Microcracks in Components
In recent years, microcracks in components due to improper handling, storage, transportation, and installation have become a new concern, arising from undue mechanical stress before and after installation.
- During handling, it is essential to prevent the packaging box from tilting, as this causes uneven stress on components, potentially leading to microcracks.
- Insufficient pallet strength can cause deformation during transportation, placing stress on the component surface and resulting in microcracks.
- Rough handling by forklift operators, severe vehicle jolts during transport, and secondary transfers can also lead to microcracks in components.
- Improper actions by workers during installation and cleaning, such as stepping on components (as shown in the example below) or maintenance personnel standing on components to clean them, can cause microcracks.
- During installation, avoid situations where a single person carries the component, where the head is used to support the component, or where the component is stepped on during installation. Installation should follow a top-to-bottom, left-to-right order.
- When carrying components, avoid using the head, shoulder, or back to support them. Instead, two people should lift one component, and simple transfer carts should be used when necessary.
- When storing components, they should not be placed or leaned against hard, uneven surfaces. Components should be installed immediately after unpacking, rather than left scattered at the project site.
These are the factors leading to microcracks in components, as introduced by Hengyuantai.
