Heavy-haul for GSU and LPT tanks
An LPT move is an oversized-load problem before it is a trucking rate problem. This page is process education. It is not a freight brokerage quote and not a claim that Switchyard Supply owns a Schnabel car.
- Route and bridge survey against the tank outline.
- Multi-state or provincial oversized permits.
- Rail / Schnabel vs highway vs SPMT last mile.
- Lifting trunnions, jack-and-slide, and pad bearing.
- Impact recorders from factory door to pad.
GAO notes that transport can run to hundreds of thousands of dollars for some moves. That is cost context, not a Switchyard Supply price. Federal rules set the oversize baseline and the states issue the permits, per FHWA guidance. After FAT, the haul plan is the next evidence close. See FAT, delivery services, and ship corridors.
