What Is a Superload?
A superload is a type of over-dimensional freight that exceeds the legal limits of standard oversize loads in weight, width, height, or length. These shipments cannot be reduced into smaller parts and often require extensive planning, multiple permits, route surveys, and escort vehicles.
Common examples of superloads include:
Cranes and construction machinery
Industrial generators or transformers
Large tanks and vessels
Wind turbine components
Bridge beams, steel structures, and pre-fabricated buildings
Superloads present significant safety and logistical challenges, which is why expert permit management is essential.
What Qualifies as a Superload?
The definition of a superload varies by state. For example:
In Massachusetts, a load over 130,000 lbs qualifies
In Pennsylvania, a load becomes a superload when it exceeds 201,000 lbs
Other states have different thresholds for weight, length, or axle configuration
Additional factors such as bridge capacity, road width, and travel times may affect your ability to move a superload legally without restrictions.
At Pro Permit Services, we manage all these requirements—state by state—to ensure your superload stays compliant from pickup to delivery.
