Stop Pallet Jams: The Complete Guide to Stacker Fork Alignment

📝 Summary
This video provides a comprehensive, step-by-step guide to
maintaining and centering telescopic forks on stacker cranes. It
covers fork types, key accuracy metrics, and practical adjustment
techniques for levelness, parallelism, and chain synchronization.

Proper fork alignment prevents costly pallet jams and rack damage
while boosting pick/put success rates. You'll learn systematic
measurement methods, shimming, eccentric roller adjustments, and how
to diagnose common faults with confidence.

Designed for automation engineers and maintenance managers, this
tutorial also includes limit sensor calibration, a seven-step
centering SOP, and a real-world case study. Apply these best
practices to maximize equipment reliability and uptime.

✨ Highlights
🔧 Master six key accuracy metrics: levelness, parallelism, straightness, stroke, sync deviation, and height difference.
⚙️ Chain synchronization is the core of fork alignment—unequal tension causes the arms to skew and drop pallets.
📊 Monthly checks of levelness, parallelism, and chain sync prevent 70% of common fork faults.
💡 Limit sensors are the safety floor; always verify calibration with a manual test cycle.
🚀 Follow the troubleshooting order: check rollers first, then chain sync, then levelness/parallelism, and sensors last.
