Why this is a quote-driven tier
Above 30,000 lb per caster the catalog effectively ends and engineered builds take over. Wheel material, diameter, plate dimensions, and bearing configuration all get specified to the exact load, floor, and travel path. Lead times run weeks, and most facility insurance requires a documented load-engineering review before deployment. Treat this as an engineered procurement, not an off-the-shelf purchase.
What movement and floor look like at 30,000+ lb
Movement is always powered — a tow vehicle or heavy tugger sized to a 120,000+ lb platform. The floor is never a given: embedded steel rail or 8-inch reinforced concrete is the baseline, with steel distribution plates as the minimum for any temporary path. The wheel diameter is driven by the floor-loading psi math, not by preference.
Common questions
Is anything in this tier a stock item?Rarely. Expect made-to-order builds with multi-week lead times. Send the application detail early.
How do I move a 120,000 lb platform?A heavy tow vehicle or tugger sized to the load and the worst grade on the route. This is specified alongside the casters, not after.
Do I need engineering sign-off?Strongly recommended, and required by most facility insurance above 25,000 lb per caster. Build the documentation chain before deployment.
