A high-cycle dock door can run for 15+ years or burn out in 4. The difference is almost always maintenance — and the work is simpler than most teams realize.
Quarterly basics
- Lubricate hinges, rollers, and bearings
- Inspect cables and springs for wear
- Check track alignment and mounting bolts
- Test photo eyes and reversing edges
