Knowledge base

Heavy haul and oversize freight, answered

What is a heavy haul freight broker?

A heavy haul freight broker is a licensed intermediary that arranges transportation for loads too heavy or too large for standard trailers. The broker does not own the trucks; it plans the move, sources an authorized motor carrier with the right specialized equipment, and coordinates the shipment. In the U.S., brokers hold FMCSA broker authority (an MC number) and file a surety bond or trust (BMC-84 or BMC-85). The Freight Dynamics operates under MC 1751787 with a $75,000 BMC-84 surety bond.

When is an oversize permit required?

An oversize or overweight permit is required whenever a load exceeds the legal limits of a state it travels through. Legal width is generally 8 ft 6 in on the National Network and Interstate gross weight is generally 80,000 lb; legal height and length are set by each state. Each state on the route issues its own permit with its own conditions.

What does an oversize load quote need?

Exact length, width, height, and weight of the item; pickup and delivery locations; how the item loads; whether it can be partially disassembled; pickup window and delivery deadline; and any site constraints such as access roads or overhead clearances. Photos or drawings speed things up.

Flatbed vs step deck: which do I need?

Choose a flatbed when freight stays within roughly 8 ft 6 in of height once loaded and can be loaded from the side or top. Choose a step deck when freight is taller — up to around 10 ft — because its lower main deck keeps the total height legal. Taller or much heavier items move on RGN or lowboy trailers.

What equipment is commonly used to move heavy machinery?

Removable gooseneck (RGN) trailers, which let self-propelled machines drive on; lowboy or double-drop trailers, whose low well carries tall equipment; multi-axle trailers for very heavy loads; and flatbeds or step decks for lighter machinery within height limits.

How should I prepare a specialized shipment?

Measure the item as it will ship, including attachments; confirm its weight from a spec sheet or scale; decide whether removing parts would bring it within legal limits; confirm the loading and unloading method and equipment at each end; note site access constraints; and share the dates you need. Clear information leads to an accurate quote and fewer surprises on pickup day.

How is construction equipment transport coordinated?

Start with the machine's dimensions and weight, choose the trailer type, check whether the move is oversize or overweight and therefore needs permits and escorts, plan the route and site access, then schedule pickup and delivery around when the crew needs the equipment.

What should I provide when booking a load?

Confirmed pickup and delivery addresses with contact names and hours, reference or PO numbers, final dimensions and weight, commodity description, loading method, appointment requirements, and who should receive status updates and delivery documentation.

Regulatory limits summarized here are general U.S. norms. Requirements for a specific load depend on the states on its route and are confirmed when we plan the move.
