Most freight moving through the Port of Savannah rides in a standard ocean container. It comes off the vessel, gets matched to a chassis, and moves through the gate on a predictable schedule. Heavy haul freight does not work that way. A transformer, a wind turbine component, an industrial press, or a piece of construction equipment that exceeds standard weight or dimension limits requires a different set of decisions before it ever reaches Garden City Terminal.
If you are researching heavy haul trucking companies serving the Port of Savannah for the first time, or refining how you evaluate specialized capacity, this article explains what heavy haul actually means, how the specialized market is structured, what creates risk for shippers, and what to look for in a partner before your next oversize shipment discharges at GPA.
Quick answer: Heavy haul trucking moves cargo that exceeds standard road weight or dimension limits, such as an oversize load, transformer, or wind energy component. It requires specialized equipment (RGN, lowboy, step deck, or flat rack), state issued over dimensional permits, and route planning that standard drayage does not. At the Port of Savannah, heavy haul is also referred to as out of gauge or project cargo, and permit lead time typically runs 24 to 72 hours before a load can leave Garden City Terminal.
Heavy haul trucking, sometimes called heavy hauling or heavy equipment hauling, refers to the transport of cargo that exceeds standard legal limits for weight, height, width, or length.
Once a shipment crosses those thresholds, it can no longer move on a standard chassis with a standard permit. It requires specialized equipment such as a lowboy, RGN, step deck, flat rack, or open top container, along with state issued over dimensional permits before the load can leave the terminal.

Heavy haul is closely related to what the industry calls project cargo and out of gauge (OOG) cargo. Project cargo generally describes large, complex shipments, often industrial or infrastructure related, that require custom planning from origin to destination. Out of gauge cargo describes freight that physically exceeds the dimensions of a standard shipping container. In practice, a single shipment at the Port of Savannah is often described using all three terms, since a heavy haul move frequently involves out of gauge dimensions moving as part of a larger project cargo shipment.
Shippers and carriers use several terms for this category of freight, including heavy haul, heavy hauling, oversize load, and out of gauge cargo. At the Port of Savannah, these terms describe the same underlying operational requirements.
Standard drayage and heavy haul transport share a starting point, a container or piece of cargo discharging at a marine terminal, but the similarities end there.
Standard drayage is repeatable: known dimensions, an available chassis, an unrestricted route, and same day dispatch. Heavy haul transport introduces variables at every stage. Equipment has to be matched to the specific cargo. Permits have to be filed and approved before the load departs, typically 24 to 72 hours depending on the states the route crosses. The route itself has to be surveyed for clearance, and in some cases escort vehicles or law enforcement coordination are required.
None of this makes heavy haul transport harder to manage. It simply requires a trucking partner who treats it as a distinct discipline rather than an oversized version of a standard move. Shippers who move standard containers regularly but are new to project cargo or out of gauge freight often underestimate this distinction, usually around permit lead time and equipment availability.

Heavy haul and OOG capacity around the Georgia Ports Authority terminals is concentrated among a relatively small set of operators who maintain the right equipment and the institutional knowledge to use it.
National and regional specialists own multi axle configurations, lowboys, RGNs, and related heavy lift equipment, often paired with rigging capability. Their advantage is depth of equipment variety and experience with extreme dimensions and weights. Alongside them are port native, asset based logistics providers whose core business is container and specialized drayage from Garden City Terminal and Ocean Terminal. Many have expanded into flat rack, open top, overweight, and selected heavy lift work because the cargo arrives on the same vessels and requires the same terminal relationships, TWIC cleared drivers, and local staging. Their advantage is proximity, responsiveness, and integration with broader port logistics.
Specialized trailers are capital intensive, slower to redeploy, and fewer in number than standard chassis. A multi axle configuration committed to one project cannot simply be swapped for the next vessel that needs it. Permit lead times add another constraint: oversize and overweight authority is issued by individual states, is load and route specific, and cannot be transferred. When a vessel schedule slips or dimensions change late, the entire critical path compresses.
These structural features produce longer effective lead times, higher sensitivity to concurrent demand across the Southeast, greater variance in response quality between operators who stage near the port and those who must source capacity from a broader network, and risk for shippers who have not pre qualified an alternative source of capacity.
Equipment ownership is necessary but not sufficient. The difference between a clean heavy haul move and a delayed one usually lies in operational readiness, the ability to sequence permits, terminal coordination, equipment staging, and driver assignment against a live vessel schedule.
Permit coordination in advance. Georgia, South Carolina, Florida, Alabama, and Tennessee each maintain distinct oversize and overweight programs. Filing windows, travel hour restrictions, escort requirements, and route restrictions differ. Operators who handle permits in house and already know the common corridors from GPA reduce both calendar time and filing risk.
Equipment match and staging. A step deck is not a double drop. An RGN configuration must match weight distribution and dimensions. Assets already in the Savannah area can be pre positioned. Assets that must travel from another region introduce both cost and schedule risk.
Terminal familiarity. Shipside or direct discharge onto specialized equipment requires coordination with the steamship line and terminal operator. Drivers need TWIC credentials and practical experience inside Garden City Terminal and Ocean Terminal procedures. Operators who run these moves regularly encounter fewer friction points on the day of discharge.
Communication under change. Vessel delays, last minute dimension updates, and free time pressure are common. The ability to re quote, re permit, and re stage without losing the move separates consistent performers from those who only handle the ideal case.
Not every heavy haul trucking company operates the same way, and the differences matter once a shipment is on the water and a discharge date is set.
| # | Question to Ask | What the Answer Tells You |
|---|---|---|
| 1 | Does the provider own its specialized equipment, or source it from a third party? | Owned equipment means a lowboy or RGN is available when the vessel discharges, not subject to a broker's availability on short notice. Ownership improves accountability and availability predictability. |
| 2 | Is permit coordination handled in house? | A company that files its own permits can begin the moment a booking is confirmed rather than waiting on an outside filing service. In house capability shortens the critical path, especially on multi state moves. |
| 3 | Does the company have direct experience with the specific cargo type at GPA? | A transformer, a wind nacelle, and a piece of construction equipment each carry different lashing, weight distribution, and routing considerations. Terminal experience reduces day of friction. |
| 4 | Where is the equipment currently staged, and how quickly can it be at the terminal for this vessel? | Distance and existing commitments matter more than fleet size on paper. |
| 5 | Is there secure yard space near the port? | Permit windows, project schedules, and crew availability can shift the timeline. Staging capacity close to the terminal lets a provider hold cargo without involving a separate facility. |
| 6 | What is the process when dimensions change or the vessel is delayed? | Clear escalation and re planning procedures protect the schedule. |
| Cargo Type | Typical Equipment |
|---|---|
| Industrial machinery and presses | Flat rack, RGN |
| Transformers and switchgear | Lowboy, multiple axle RGN |
| Wind energy components | Step deck, oversize flat rack |
| Construction and agricultural equipment | RGN, lowboy, step deck |
| Project cargo and breakbulk shipments | Custom flat rack or open top container |
The Port of Savannah has become one of the busiest gateways on the East Coast for heavy haul and project cargo, driven in part by manufacturing growth across the Southeast, including automotive and battery plants inland from GPA, and continued expansion of energy and industrial infrastructure.
That growth means more oversize freight, more out of gauge cargo, and more shippers researching heavy haul trucking companies near Garden City Terminal for the first time. A trucking partner with a long operating history at GPA understands the terminal's discharge procedures, the state permit pathways for common inland routes, and the practical realities of staging heavy equipment near the port. That experience shortens planning time on a category of freight where planning time is the primary cost driver.
Georgia, South Carolina, Florida, Alabama, and Tennessee each manage their own over dimensional permit programs, with separate agencies, filing requirements, and rules governing allowable travel hours. A heavy haul shipment moving inland from GPA to a facility in a neighboring state passes through more than one jurisdiction, and each one has to be permitted before the load departs. A provider that files these permits in house, rather than routing the work through a third party, can begin the process the moment a booking is confirmed.
Standard drayage moves a container on a standard chassis within normal weight and size limits, with no permits required and same day dispatch available. Heavy haul transport requires specialized equipment, state issued over dimensional permits, and route planning before the load can move.
Permit lead time typically runs 24 to 72 hours depending on how many states the route crosses, and that clock should start as soon as a vessel's discharge window is known. Shippers coordinating a multi state move should build permit lead time into their overall project cargo schedule rather than treating it as a final step.
Yes. A single asset based provider that runs both standard chassis and specialized heavy haul equipment out of the same facility can coordinate a shipment that includes both container freight and out of gauge cargo without handing off between vendors.
Late dimension or weight changes often require re permitting and equipment re matching. Operators with in house permit capability and equipment staged near the port can typically absorb these changes with less delay than operators who source capacity and filing support from a broader network.
The terms overlap. An oversize load generally refers to cargo that exceeds standard road dimensions, while heavy haul describes the equipment and permitting discipline used to move it. Most oversize loads at the Port of Savannah are handled as heavy haul or out of gauge shipments.

Savannah Logistics Services operates the Port of Savannah business formerly known as Savannah River Logistics, acquired by the Komar family of companies in 2025. The team has moved out of gauge and specialized freight at Garden City Terminal for 25 years, alongside standard container drayage.
Our fleet includes more than 80 owned tractors and 300 owned chassis, along with the specialized trailers required for flat rack, open top, and over dimensional moves. Permit coordination and route planning are handled in house. Facilities sit within 11 miles of the port gates, allowing equipment to be staged against vessel schedules rather than sourced reactively.
A single piece of industrial equipment and a multi shipment project cargo schedule both run through the same team, the same equipment pool, and the same permit process. For shippers, that means local, asset based capacity that operates on the daily rhythm of the Port of Savannah rather than being sourced in from outside the region.
