Overworked Railroad Springs
Application: Slack Adjuster Springs
Problem: Existing spring design was getting worked over in application and breaking in service.
The MWI Solution:
- Analyzed physical failure points and overall application design
- Developed a new chrome silicon spring design to allow for more clearance
- Added an “E” coating and performed an extensive shot peening process
Repairs were done using the new springs, in-service breakages were eliminated, and the customers’ later product designs have incorporated the revised spring characteristics.
