Welding Rotator Sizing System
Size your equipment based on real-world eccentric loads, not just headline weight. This tool applies a strict 1.5× safety factor plus off-center derating to ensure operational safety and machine longevity.
1.5× Dynamic Safety Factor
Accounts for rotational inertia and minor fabrication variances during heavy submerged arc welding.
Eccentricity Derating Algorithm
Automatically calculates effective load demand when the center of gravity shifts off-axis.
Calculate Required Capacity
Disclaimer: Indicative only. Off-center loads cut rated capacity sharply. The eccentric-load chart for your exact model governs. Our engineering team will confirm final specifications against your CAD drawings.
