Scrapping Standards for Brake Wheels of Overhead Cranes
2026-02-25
Wear degree: When the working surface of the brake wheel wears to a certain extent and the thickness reduction exceeds 20%-30% of the original thickness, it should be scrapped.
Cracks: If any form of cracks, whether surface cracks or internal cracks, appear on the brake wheel, it should be scrapped immediately.
Deformation: If the brake wheel is significantly deformed due to uneven stress or other reasons, affecting normal use, it should be scrapped.
Corrosion: If severe corrosion occurs on the surface of the brake wheel, affecting its mechanical performance and safe use, it should be scrapped.
Fatigue damage: If fatigue damage, such as surface spalling or local indentation, occurs on the brake wheel after long-term use, it should be scrapped.
These standards are to ensure the safety and reliability of the overhead crane during operation and to avoid safety accidents caused by brake wheel failure. The specific scrapping standards may vary depending on the crane model and operating environment. It is recommended to refer to the relevant equipment maintenance manual and national/industry standards.
