Oversized transportation is a highly specialized segment of the logistics industry, involving the transportation of cargo that exceeds the standard legal size or weight limits set by transportation authorities. These loads, commonly referred to as “oversize” or “over-dimensional”, include everything from industrial machinery and wind turbine components to large construction equipment and prefabricated structures. Because of their size and complexity, moving these items requires meticulous planning, specialized equipment, and strict regulatory compliance.
What Qualifies as Oversized Freight?
Freight is generally considered oversized if it exceeds:
- Width: Over 8 feet 6 inches
- Height: Over 13 feet 6 inches (varies by region)
- Length: Over 53 feet (for a standard trailer)
- Weight: Over 80,000 pounds gross vehicle weight
Any cargo that goes beyond these thresholds typically falls into the oversized category and necessitates additional permitting and resources.
The Planning Process
Oversized freight shipping is not as simple as loading cargo onto a trailer and hitting the road. It requires weeks, or months, of preparation. Here’s a look at the essential steps:
- Route Surveys and Planning
Before transport begins, a detailed route survey is conducted. This involves mapping out a path that can accommodate the cargo’s size and weight. Factors considered include:
- Bridge height and weight limits
- Road width and surface conditions
- Sharp turns and inclines
- Traffic patterns and construction zones
In many cases, alternative routes must be found to avoid low overpasses or narrow roads, adding complexity to the planning process.
- Permitting and Regulations
Oversized freight must comply with local, provincial, and federal regulations. Shippers must obtain:
- Oversize/overweight permits from each province the load will travel through
- Escort or pilot car if the jurisdiction requires it
- Time-of-day restrictions, as some jurisdictions limit travel to daylight hours or specific times to reduce traffic impact
Failure to secure proper permits can lead to fines, delays, or even accidents, making this step critical.
- Coordination with Authorities
Transporting oversized loads often requires coordination with:
- Departments of Transportation
- Utility companies to raise power lines or move signage
- Law enforcement for traffic control during transport
Prepping for the Shipment
- Load Securement
Because oversized loads often sit higher or wider than the vehicle transporting them, ensuring they are securely fastened is paramount. Load binders, dunnage, chains, straps, and tarps are commonly used to minimize movement and protect the cargo.
- Specialized Equipment
Standard trailers can’t handle most oversized loads. Instead, carriers use:
- Lowboy trailers for heavy equipment
- Extendable flatbeds for long loads
- Multi-axle trailers to distribute extreme weight
The right equipment not only protects the cargo but also ensures the safety of the transport crew and the general public.
Timing and Advanced Planning
Oversized shipments are rarely last-minute. Lead times can range from several days to several weeks, depending on the cargo’s size and the complexity of the route. Factors like weather, road construction, and regulatory reviews can cause delays, so shippers must build flexibility into their schedules.
Advance planning also involves:
- Risk assessment and contingency planning
- Insurance verification
- Communication with all stakeholders, including clients, carriers, and regulatory bodies
