Heavy Equipment Shipping: How to Transport Machinery & Oversized Loads

What Qualifies as Heavy Equipment?

Heavy equipment is any machinery or industrial asset that exceeds standard freight dimensions or weight thresholds. The federal gross vehicle weight limit on interstate highways is 80,000 pounds, which includes the truck, trailer, and cargo combined. Once your load pushes past those limits, you're in heavy haul territory.

But weight is only half the equation. Dimensions matter just as much. The standard legal limits for freight on US highways are:

• Width: 8 feet, 6 inches
• Height: 13 feet, 6 inches (varies by state)
• Length: 53 feet (trailer)
• Weight: 80,000 lbs gross vehicle weight

Anything that exceeds even one of those thresholds requires special permits, specific trailer types, and in many cases, escort vehicles.

Common Types of Heavy Equipment Shipped

• Excavators (20,000 to 180,000+ lbs)
• Bulldozers (15,000 to 105,000 lbs)
• Cranes and crane components
• Wheel loaders and backhoes
• Compactors and pavers
• Agricultural equipment (combines, tractors)
• Mining equipment
• Industrial generators and transformers
• Construction site trailers and modular buildings

Never assume that a piece of equipment falls within legal limits based on appearance alone. A mid-size excavator with the boom extended can exceed height, width, and weight limits simultaneously.

Types of Trailers for Heavy Equipment

The trailer is the foundation of every heavy equipment move. Choosing the wrong one leads to loading problems, permit complications, and safety risks during transit. Here are the primary options for heavy equipment transport.

Flatbed Trailer

The standard workhorse of open freight. Flatbed trailers sit roughly 60 inches off the ground and handle loads up to approximately 48,000 pounds. They work well for equipment that fits within legal height limits and can be loaded by crane or forklift.

Best for: smaller equipment, machinery components, steel structures. For a deeper look at flatbed capabilities, see our flatbed shipping guide.

Step Deck (Drop Deck) Trailer

A step deck drops the rear section of the trailer down to around 38 inches off the ground, giving you an extra 12 to 18 inches of vertical clearance compared to a standard flatbed. The front section remains at standard height.

Best for: taller equipment that would exceed height limits on a flatbed, such as forklifts or small wheel loaders.

Lowboy / RGN (Removable Gooseneck) Trailer

This is the go-to trailer for heavy equipment shipping. The deck sits as low as 18 to 24 inches off the ground, providing maximum height clearance and a low center of gravity for stability. RGN trailers have a removable gooseneck that detaches from the front, creating a ramp for drive-on loading.

An RGN is the only practical option for self-propelled equipment like dozers and excavators. The machine drives right onto the trailer under its own power.

Best for: excavators, bulldozers, large loaders, cranes, and anything over 12 feet tall.

Double Drop Trailer

Similar to a lowboy, but the deck drops in two stages, creating an extremely low well section in the middle. Double drops handle tall, heavy items that need both low deck height and maximum legal height clearance.

Best for: industrial equipment, large generators, transformers, and tall machinery.

Multi-Axle / Specialized Trailers

For the heaviest loads, multi-axle trailers distribute weight across 9, 13, or even 19+ axles. These trailers handle loads exceeding 100,000 pounds and require specialized engineering for each move.

Best for: mining equipment, industrial turbines, bridge beams, and anything where weight alone makes the shipment extraordinary.

How Heavy Equipment Shipping Works

Every heavy equipment shipment follows a structured process. Skipping steps leads to delays, damage, or regulatory violations. Here's the step-by-step breakdown.

Step 1: Assess Dimensions and Weight

Measure the equipment precisely. Length, width, height, and weight determine everything that follows: trailer type, permits, route, escorts, and cost. Get exact specs from the manufacturer or measure the equipment yourself with the machine in transport configuration (boom down, blade retracted, attachments removed where possible).

Step 2: Choose the Right Trailer

Based on dimensions and weight, select the appropriate trailer type. A 25,000-pound skid steer fits on a standard flatbed. A 50,000-pound excavator needs an RGN. A 120,000-pound mining truck needs a multi-axle trailer with engineered load plans.

Step 3: Obtain Permits

If the loaded truck exceeds any legal dimension or weight threshold, you need permits. Every state on the route requires its own permits. Some states process permits in hours. Others take weeks. Your carrier or broker handles this, but the timeline directly impacts your shipping schedule.

Step 4: Plan the Route

Oversize loads cannot take just any road. Low bridges, narrow lanes, weight-restricted roads, and construction zones all create obstacles. For heavy haul shipments, a route survey may be required to verify bridge ratings, turning radii, and overhead clearances.

Step 5: Load the Equipment

Loading methods depend on the equipment and trailer. Self-propelled machines drive onto RGN trailers. Non-running equipment gets loaded by crane or pushed with another machine. Every piece of equipment must be secured with chains, binders, and straps rated for the load weight.

Step 6: Transport

The driver follows the permitted route. Escort vehicles travel ahead and behind for oversize loads. Transit speeds for heavy haul are typically slower than standard freight, often limited to 45 to 55 mph depending on state regulations and load characteristics.

Step 7: Offload at Destination

The equipment is unloaded using the reverse process. The job site or receiving facility needs adequate space, solid ground, and sometimes a crane for non-operational equipment. Confirm site readiness before the truck arrives.

A bill of lading documents the entire shipment from pickup to delivery. Make sure the condition of the equipment is noted on it at both ends.

Heavy Haul vs. Standard Flatbed

Standard flatbed shipping handles loads within legal size and weight limits. Heavy haul is a different category entirely.

You cross into heavy haul territory when any of the following apply:

• Gross vehicle weight exceeds 80,000 lbs
• Load width exceeds 8'6"
• Load height exceeds 13'6"
• Load length exceeds legal limits for the trailer type

The differences between standard flatbed and heavy haul go beyond size.

Permits. Standard flatbed loads require no special permits. Heavy haul loads require permits in every state on the route, and sometimes county-level permits too.

Escort vehicles. Loads exceeding certain width or length thresholds require pilot cars. Some states mandate front and rear escorts for loads over 12 feet wide. Extremely large loads may require police escorts.

Travel restrictions. Heavy haul loads are often restricted to daylight hours, banned from travel during holidays, and prohibited on certain roads. A standard flatbed runs 24/7 with no route restrictions.

Equipment. Heavy haul carriers invest in specialized trailers, rigging equipment, and driver training that standard flatbed carriers do not carry.

The permit process alone is why most shippers use a broker for heavy equipment moves. A single cross-country shipment might require permits from six different state DOT offices, each with its own application process, fee schedule, and processing time.

Costs of Heavy Equipment Shipping

Heavy equipment shipping costs more per mile than standard freight. The specialized trailers, permits, escorts, and slower transit speeds all contribute to higher rates. Here's what drives the price.

Rate Factors

• Distance: The single biggest cost driver. Longer hauls cost more, but the per-mile rate decreases on longer lanes.
• Weight: Heavier loads require more expensive trailers and higher permit fees. Multi-axle trailers cost significantly more than standard equipment.
• Dimensions: Oversized loads that need escorts and special permits add $500 to $2,000+ per day in escort costs alone.
• Origin and destination: Urban pickups and deliveries with tight access add cost. Remote job sites with unpaved roads add cost. Both add complexity.
• Permit fees: State permits range from $15 to $200+ per state, depending on the load and the state. Multi-state moves add up fast.
• Seasonality: Construction season (spring and summer) drives up demand and rates for heavy equipment transport.

Typical Cost Ranges by Equipment Type

These ranges assume a 500-mile move and provide a general baseline:

These are estimates. Actual costs depend on the specific origin, destination, load configuration, and current market conditions.

Permits and Legal Requirements

Permits are the single most complex part of heavy equipment shipping. Every state has its own rules, and they change frequently. Here's what you need to know.

Overweight Permits

Required when the gross vehicle weight exceeds 80,000 pounds. Each state along the route issues its own overweight permit. Some states allow single-trip permits. Others offer annual permits for frequent heavy haul carriers. Fees vary widely.

Oversize Permits

Required when the load exceeds legal width, height, or length limits. Oversize permits are separate from overweight permits. A load can require both.

Route Surveys

For extremely heavy or large loads, the state may require an engineering route survey. This verifies that every bridge on the route can handle the weight, every overpass provides adequate clearance, and every turn is navigable. Route surveys add time and cost but prevent catastrophic problems during transit.

Escort Vehicles

States require escort (pilot) vehicles based on load dimensions. Common thresholds:

• Over 10 feet wide: One escort vehicle (some states)
• Over 12 feet wide: Front and rear escorts (most states)
• Over 14 feet wide: Front and rear escorts plus possible law enforcement escort
• Over 16 feet wide: State-specific requirements, often including police coordination

State Variations

This is where heavy equipment shipping gets complicated. Texas might allow a load to travel at night that Oklahoma prohibits after dark. Illinois might require two escorts for a load that Indiana allows with one. Georgia might process a permit in 30 minutes that California takes two weeks to approve.

A carrier or broker with heavy haul experience knows these variations and plans for them. An inexperienced carrier will learn them the hard way, at your expense.

Preparing Equipment for Transport

Proper preparation prevents damage, reduces liability, and speeds up the loading process. Never skip these steps.

Drain or Secure Fluids

Hydraulic systems should be depressurized. Fuel tanks should be at or below one-quarter full to reduce weight and spill risk. Coolant levels should be checked and caps tightened. Any fluid that could leak during transport needs attention before the equipment goes on the trailer.

Secure All Attachments

Buckets, blades, booms, and arms should be lowered to their transport position. Remove any detachable attachments (augers, thumbs, rippers) and ship them separately or secure them to the trailer deck. Loose components become projectiles at highway speed.

Disconnect Batteries

For long-distance moves, disconnect the battery to prevent accidental starts, electrical drain, or short circuits during transport. Tag the disconnect point so the receiving crew knows the battery was intentionally disconnected.

Retract and Lock Moving Parts

Anything that telescopes, swivels, or articulates needs to be retracted and locked. Outriggers on cranes. Telescoping booms on aerial lifts. Articulation locks on loaders. If it moves, lock it down.

Photo Documentation

Photograph every side of the equipment before it goes on the trailer. Capture existing damage, hour meter readings, and the overall condition. This documentation is your evidence if a damage claim arises. Take photos at both pickup and delivery.

This is the step that most shippers skip and most regret skipping.

Clean the Equipment

Remove excessive dirt, mud, and debris. Some states prohibit transporting equipment that drops mud or debris on roadways. A clean machine also makes pre-transport inspection and photo documentation easier.

Loading and Unloading

Loading heavy equipment onto a trailer is one of the highest-risk moments in the entire shipping process. The right approach depends on the equipment, trailer, and site conditions.

Drive-On Loading (RGN Trailers)

The safest and most efficient method for self-propelled equipment. The RGN gooseneck detaches, creating a gradual ramp. The machine drives up under its own power and is then secured with chains and binders. This method requires a skilled operator who understands the trailer's weight distribution requirements.

Crane Loading

Non-operational equipment or machinery without tracks or wheels requires crane loading. A mobile crane lifts the equipment onto the trailer. This requires advance coordination for crane rental, rigging plans, and lift engineering for heavier pieces.

Ramp Loading

Some step deck and flatbed trailers use portable ramps for loading wheeled equipment. Ramp loading requires stable, level ground and careful attention to ramp weight ratings.

Site Preparation

The loading and unloading site needs to support the operation. Requirements include:

• Firm, level ground (no soft soil that will sink under heavy loads)
• Adequate clearance for trailer maneuvering
• Overhead clearance for tall equipment
• Access roads that can handle the truck and trailer length and weight
• Space for escort vehicles if applicable

Confirm site conditions at both ends of the move before the truck dispatches. A truck arriving to find a muddy unpaved lot and no way to turn around is an expensive problem.

Insurance for Heavy Equipment Transport

Standard carrier cargo insurance may not cover the full value of your equipment. Heavy machinery can be worth $50,000 to over $1,000,000. Never assume the carrier's policy is enough.

Carrier Cargo Insurance

Most carriers maintain cargo insurance, but policy limits vary. A carrier with $100,000 in cargo coverage cannot adequately insure a $500,000 excavator. Ask for the carrier's certificate of insurance and verify the coverage amount, deductible, and exclusions before your equipment goes on the trailer.

Equipment Valuation

Declare the full value of the equipment on the bill of lading. Underdeclaring the value to save on freight costs will backfire if a claim arises. The carrier's liability is typically limited to the declared value.

Supplemental Cargo Insurance

For high-value equipment, purchase supplemental cargo insurance through your broker or a third-party insurer. This fills the gap between the carrier's policy limits and the actual value of your equipment.

Liability During Loading

Loading and unloading present the highest risk for damage. Clarify in writing who is liable during the loading process. Some carriers accept liability from the moment their trailer arrives. Others limit liability to the transit period only.

The conversation about insurance needs to happen before the shipment, not after a $200,000 excavator slides off a trailer.

Choosing a Heavy Equipment Carrier

Never ship heavy equipment with a carrier that doesn't specialize in it. A carrier that runs great full truckload routes may have zero experience securing a D6 dozer to a lowboy or navigating oversize permits across multiple states.

Here's what to evaluate.

Specialization

Ask how many heavy equipment loads the carrier moves per month. Ask what types of equipment they handle most frequently. A specialized heavy haul carrier will have purpose-built trailers, experienced drivers, and established permit relationships with state DOT offices.

Equipment

Verify the carrier owns or leases the specific trailer type your load requires. A carrier that needs to broker out to a subcontractor for a lowboy is adding cost and reducing accountability.

Insurance

Request the certificate of insurance. Verify limits, deductibles, and that the policy covers the type of equipment you're shipping. Do not accept verbal assurances.

DOT Authority and Safety Record

Check the carrier's DOT number and safety record through the FMCSA's SAFER system. Look at crash history, inspection results, and out-of-service rates. A carrier with a poor safety record is a liability.

References

Ask for references from other shippers who have moved similar equipment. A reputable heavy equipment carrier will have them ready.

Working with a Broker

Many shippers use a freight broker for heavy equipment moves instead of contracting directly with a carrier. A broker with heavy haul expertise manages the entire process: carrier selection, permit coordination, route planning, and insurance verification. For shippers who move heavy equipment infrequently, a broker provides the specialized knowledge without the learning curve.

For smaller or time-sensitive heavy equipment moves, hotshot trucking may also be an option worth exploring.

Real-World Example: Moving a D6 Dozer from Texas to Colorado

A construction company in Houston needed a Caterpillar D6 bulldozer delivered to a job site outside Denver. Here's how the move played out.

The equipment: CAT D6T, approximately 44,000 lbs operating weight, 15 feet 5 inches long, 8 feet 10 inches wide with the blade, 10 feet 8 inches tall with the cab.

Trailer selection: RGN lowboy. The dozer's weight and width made this the only practical choice. The low deck height kept the total loaded height under 13 feet 6 inches, avoiding oversize height permits.

Permits required: The load was legal on height and length but overwidth by 4 inches and overweight once you added the truck, trailer, and dozer together. Overweight and overwidth permits were required in Texas, New Mexico, and Colorado. Total permit processing time: four days. Total permit cost: approximately $380.

Route: I-25 north through New Mexico into Colorado. A route survey was not required because the gross weight stayed under the state bridge formula thresholds for the trailer's axle configuration.

Escorts: One pilot car required in New Mexico and Colorado due to the overwidth condition. Texas did not require an escort for the load's width. Escort cost: approximately $1,100 for the two-state stretch.

Loading: The dozer was driven onto the RGN at the construction yard in Houston. Blade lowered, ripper raised and pinned, battery disconnected. Four chain tie-downs secured the machine to the trailer. Total loading time: 45 minutes.

Transit: 1,050 miles. Two-day transit with an overnight stop in Albuquerque. The driver coordinated with the pilot car for the New Mexico and Colorado segments.

Total cost: Approximately $4,200 including transport, permits, and escorts.

Delivery: The dozer was offloaded at the Denver job site by driving it off the RGN. The site foreman inspected the machine against the pre-shipment photos and signed the bill of lading with no exceptions noted.

The whole process took six days from first call to delivery. Four of those days were permit processing.

Frequently Asked Questions

How much does it cost to ship heavy equipment?

Costs vary widely based on equipment size, weight, distance, and permit requirements. A mid-size excavator shipped 500 miles typically costs between $2,000 and $5,000. Larger machines on longer routes with multiple state permits and escort requirements can cost $10,000 or more. Request a quote for pricing on your specific move.

What is the heaviest load you can ship on a truck?

There is no hard upper limit. Multi-axle trailers can haul loads exceeding 200,000 pounds with the right permits, route engineering, and escort coordination. The practical limit depends on state regulations, bridge weight ratings along the route, and the availability of specialized trailers.

Do I need permits to ship heavy equipment?

You need permits if your loaded truck exceeds any legal size or weight limit. That means gross vehicle weight over 80,000 lbs, width over 8'6", height over 13'6", or length beyond standard limits. Permits are issued per state, so a multi-state move requires permits from each state on the route.

How long does heavy equipment shipping take?

Transit time depends on distance and permit complexity. A 500-mile move with all permits in hand takes one to two days of transit. But permit processing can add three days to two weeks depending on the states involved. Plan ahead. Start the permitting process as early as possible.

Can non-running equipment be shipped?

Yes. Non-running equipment is shipped using crane loading or by pushing/towing it onto the trailer with another machine. This adds cost for the loading equipment but is a routine part of heavy equipment transport. Let your carrier know the equipment is non-operational at the time of quoting so they can plan accordingly.

What is an RGN trailer?

RGN stands for Removable Gooseneck. The front section of the trailer detaches and lowers to the ground, creating a ramp for drive-on loading. RGN trailers are the standard choice for shipping self-propelled heavy equipment like excavators, dozers, and loaders because of their low deck height and drive-on capability.

Who handles the permits for oversized loads?

The carrier or freight broker typically handles all permit applications. Experienced heavy haul carriers have permit departments or use third-party permit services that know each state's requirements, fees, and processing times. This is one of the strongest reasons to use a specialized carrier or broker instead of trying to manage heavy equipment shipping independently.

Should I use a broker or go direct to a carrier for heavy equipment shipping?

For most shippers, a broker with heavy haul expertise is the better choice. Brokers maintain relationships with multiple specialized carriers, handle permit coordination across states, verify insurance, and manage the logistics of the entire move. Going direct to a carrier makes sense only if you ship heavy equipment frequently and have an established relationship with a proven heavy haul carrier.
