Why extreme loads go on track
At 18,000 lb per wheel, free-roaming swivel casters are a liability — the cart is too heavy to correct by hand if it drifts, and a collision at that mass is a serious event. Track casters remove the variable: the rail constrains the cart, every cycle, regardless of load. Flanged wheels for the heaviest builds, heavy V-groove where angle rail is in place.
Rail and floor at this tier
Heavy track casters need engineered rail — properly anchored, properly sized steel — and the floor under the rail has to carry the point load. This is an engineered installation: the rail spec, the anchoring, and the floor design are part of the project, not an afterthought. Powered movement (tugger or tow vehicle) is assumed.
Common questions
What's the difference from standard track casters?Capacity — heavy track casters reach 18,000 lb per wheel. The guidance principle is the same; the construction and rail are heavier.
Do these require engineered rail?Yes — at 18,000 lb per wheel the rail, anchoring, and floor are an engineered installation, not bolt-on hardware.
Flanged or grooved at this load?Flanged is common at the extreme end — the lip over the rail edge is positive retention. Heavy V-groove works where precise angle rail exists.
