At SIS Transportation, we offer specialized freight transportation services for heavy and oversized loads across the continental United States. From coast to coast, our team is equipped to move the equipment and materials that power America’s industries — safely, efficiently, and on time.

We focus exclusively on flatbed freight transportation, handling complex hauls that require more than standard shipping solutions. Our fleet is capable of transporting a wide variety of heavy and high-value cargo, including:

• Construction equipment (excavators, bulldozers, loaders)

• Cranes and crane components

• Steel beams and structural materials

• Generators and transformers

• Industrial machinery and plant equipment

• Oversized HVAC units

• Precast concrete components

• Agricultural equipment

Whether you’re moving freight across a single state or across the country, we’re equipped to deliver. We handle all the logistics — from securing proper permits and escorts for oversized loads to selecting optimal routes that meet state regulations and reduce delays. We also provide load securement expertise and offer custom solutions tailored to the specific needs of each job.

With experienced drivers, specialized flatbed trailers, and a deep understanding of DOT compliance and heavy-haul logistics, we’ve earned the trust of contractors, manufacturers, and industrial operators nationwide. No matter how large, heavy, or complex your shipment may be, we have the equipment and experience to move it — from job site to job site, warehouse to factory, or coast to coast.

Let us handle the heavy lifting, while you focus on getting the job done.
