Project Description

Barrier Assist Springs

Application: Emegency Barrier Assist Springs

Problem: Original extension spring design was consistently failing long before the desired life of 500,000 cycles.

The MWI Solution:

  • Developed a unique double-coil extension spring to reduce the stresses
  • Designed a custom spring anchor assembly in lieu of hooks or other end types
  • Special processes and tooling developed to allow a full shot peening and “E” coating


The customer replaced all the springs with the new spring assembly. To date, there has only been one broken assembly, which had well over 350,000 cycles behind it.
