How Heavy Equipment Shipping Works: Oversize Permits, Trailers, Routing and Costs

Ownership & Services

Heavy Equipment Shipping Guide: Permits, Trailers and Costs.

Learn how permits, trailer selection, routing, loading and distance affect the cost and planning of heavy equipment shipping.

Buying the machine is only part of the transaction. You still have to move it. For large excavators, crushers, batch plants, cranes and loaders, transportation can become a project of its own.

Start with accurate machine dimensions

Gather operating weight, overall width, transport height, transport length, attachments, pickup and destination, and whether the machine can load itself. A quote is only as good as the information supplied.

Why legal dimensions matter

Federal rules establish a framework for the Interstate and designated network, while oversize and overweight permitting is handled through individual states and jurisdictions. FHWA identifies a federal maximum vehicle width of 102 inches—8 feet 6 inches—on the National Network, subject to applicable exceptions and rules.

Oversize permitting is not one national permit

A move crossing several states may require approvals from multiple jurisdictions. Route restrictions can involve bridges, overhead clearance, construction, local roads and seasonal limits.

The trailer matters

Common configurations include flatbeds, step decks, removable goosenecks, lowboys, multi-axle lowboys and specialized heavy-haul trailers. The correct setup is determined by actual dimensions and weight, not merely equipment category.

Can attachments be removed?

Sometimes removing a bucket, blade, counterweight or other component reduces width, height, length or axle weight. But removal adds labor and freight pieces, so the decision should be route-specific.

What drives transport cost?

  • Mileage
  • Machine weight
  • Width, height and length
  • Trailer type
  • Permits
  • Escort vehicles
  • Route restrictions
  • Loading/unloading assistance
  • Fuel and carrier availability

Loading preparation

Confirm the machine runs, the loading surface is suitable, attachments are secured, loose material is removed, keys are available and loading personnel are present. Tell the transporter in advance if the machine is non-running.

BigEquipCo transport quote checklist

Exact pickup, exact destination, make/model, operating weight, width, height, length, attachments, running condition and any loading limitations.

Quote shipping before committing

A cheaper machine 1,500 miles away may not be cheaper delivered than a higher-priced machine 100 miles away. Compare machine + freight + permits + loading + timing + risk.
